Refurbishing / Replacing the Subwoofer (Post #633) 11/26/2023

Subwoofer work

Ever wonder what is inside of that gigantic custom-fit subwoofer box in the back of your Range Rover Classic…well wonder no more. I had to pull all the parts of the sound system out of the Big White Bus to investigate my rust issues.

It takes a few bolts to get it out but everything is easy-ish to get to and you don’t need any special tools. Take the amplifier off the subwoofer box. Then tackle all the bolts. Once the subwoofer is out you can get to the antique CD changer. Actually in 1993 a six disc CD changer was straight up gangster. My CD changer worked for a few years. It then got a little buggy. You could get it to work if you slid it out and slammed it back in. Most of the time it started to be available at the head unit after that.

It all has to come out. I have a new head unit. I have new speakers. I don’t know if the amplifier still works. I will have to sit down at some point and try to figure out all the plugs and see if the amplifier will be part of the equation. Having a working subwoofer would be a nice addition.

Once the subwoofer is out it takes 10 screws and a little gentle encouraging and the box will come apart. It’s a relatively simple setup. There is a dual cone speaker inside and that’s it. Mine as you will see in the video is toast. the cone has disintegrated. It is at least 30 years old probably closer to 33 considering assembly line technology of the day.

So the speaker will need to be replaced. In the video I speculate about the size but it turns out to be:

  • Cutout Diameter 6.5 inches
  • Top Depth mounting 3 inches
  • Bottom Depth Mounting 3.25

There are a LOT of speakers to choose from online. I went to Crutchfield.com. They don’t sponsor me, I wish they did, but they don’t. They have great customer service and the spec’s for everything are easy to find on their site.

I found a speaker that looks like it will fit.

That’s not a lot of money and 4 people think it’s pretty awesome. Mounting that is still a question, but I’m not worried. I will figure it out if that is the direction I go.

There is some debate going on in my head about replacing the old one with a NEW subwoofer. I found a Kenwood on Crutchfield that was not all that expensive.

Kenwood Excelon
ribbed polypropylene cone, sounds naughty….

It’s pretty small too. Just a little under 18x12x6 inches. I’m certain I’d have to cover the speaker cause it would almost certainly get damaged if I didn’t. I am confident it would fit in the space. But the real question outside of would it be better is…. am I really saving enough space to matter? I’m not sure I would gain anything. The space would have to be VERY creatively designed to take advantage of a few inches more here or there.

This gives us the cheaper option of just buying the speaker and figuring out how to wire it to the old AMP and the new head unit. Another plus of this operation was the elimination of the CD player gives me 12 volt switched power line back in that corner. That might come in handy, who knows.

I like tunes as much as the next guy. I even have a playlist named, “Can’t Be Too Loud”. It’s got some songs that you turn up until your ears bleed.

  • Van Halen’s Eruption
  • AC/DC Back In Black
  • Living Colour’s Cult of Personality
  • Beastie Boys Sabotage
  • Black Sabbath’s Iron Man
  • Wagner’s Die Walk├╝re (Ride of the Valkyrie)
  • Carl Orff’s O Fortuna from Carmina Burana

There are more, but you get the picture…you probably have a list of your own. Whenever I hear these songs I turn them up to maximum volume.

Mostly today…I listen to audio books. Sooooo many audio books. It’s not uncommon for me to just drive, no music, just the window down and the sound of the engine and the tires on the road. That recharges my batteries almost as just sitting in the woods next to a fire.

There is a lot left to do to get the sound system installed. I’ve got to sort out the plugs and get everything wired up. The dash is still not installed. There is an order to putting the BWB back together…and the windshield needs to be first. I’m almost certain there is water leaking in and the last thing I want is to get his all put back together and still having water coming in.

That’s it for this week. As soon as I make a decision I’ll post it up and when I starting putting the sound system together.

Fender Repair Part 6, Reassembling the Fender and Mud Flap (Post #623) September 9, 2023

What?

Finishing up.

In this video I’m wrapping up the quarter panel rust tasks. I got a rattle can of “bed liner” sprayed on. It took the entire can! I will probably apply another application just to be sure.

The fender install went “smoothly” until I realized later that I forgot to plug the light cluster in. So I got to do that job twice. You only get to see the excruciatingly painful initial time. I saw a funny meme. The scene is a spring install with the narrator saying something to the effect that doing a job required on both sides of the vehicle.

  • First time 2 days and 89 hours.
  • Second time 29 minutes.

Ain’t that the truth though! So it’s been a hot minute (as my kids say) since I reinstalled a fender. So it went not quite so well the first time. I did cuss some. But that’s the nature of working on cars after all, is it not?

I talk about having to remove the glass on the passenger (starboard) side to complete the welding that needs to be done on the D pillar. I also talk about how outrageously expensive new window seals will be.

I did watch a couple of videos on how to do it. One of them is listed here:

The the hell is “duck water”??

So you can see getting the window AND seal out in one piece is going to save me a LOT of money.

Lastly I tried to start the Big White Bus. After charging the batter over night, she would not start. I got one cough, but otherwise a whole lot of nothing. The relay is working, but I am not hearing the pump run. I’ll need some help with diagnosing spark and electrics at the pump. So I put this off until next weekend when I can either get my buddy Larry over, or press my son into service.

I also tried out a new camera. My son had a GoPro Hero 5 just sitting around so I

confiscated it indefinitely borrowed

asked him if I could use it. Yeah, he’s not likely to get it back. I bought a new SIM for it. The SIM I was using doesn’t work in my Hero 11 and gives me a message about that. The Hero 5 did not give me a similar message so I thought it was good to go. It was not. So you missed out on 5 minutes of riveting footage of me walking back and forth in front of the camera and using a dustbin to sweep up and spraying bedliner. I’m sure it was the difference in this week’s video being a smashing success. Que sera, sera.

Fender Repair Part 2, Welding Patches (Post #618) August 5, 2023

Welding the corner

Today started out “cool”. At least it was cool for an August on the southern plains. The temp was lower than I thought and clouds covered the northern sky and looked to be moving south. This usually says we are going to get a break in the hot temps. We’ve been 24 days without rain. But with all things weather in Oklahoma, a full cloud cover did not offer any relief from the heat.

Regardless I need to make some progress on the Big White Bus if I’m ever going to drive her again. So after a little bit of trimming of the hedgerow between my neighbor and our house I got to work. Sticking with the theme of welding for this summer, repairing the rust in the fender seemed like a great idea.

I had four places in the fender that needed repair before I started today. I am now down to two. I repaired a small rust spot and repaired the corner of the fender.

I fixed one spot with a simple rectangle and welded it up in short order.

The corner was a complicated piece to fix. The patch for the corner was somewhat shaped like a trough? I don’t have the tools to make that happen. I tried hammering a piece of 16 gauge into a trough but really didn’t have any luck.

I got a bit of inspiration and decided that if I put the patch in and shaped it like one of the complex sides I could perhaps hammer it to fit the other complex shape. So with a bunch of vise-grips I got the patch in place and went to work with the hammer. I worked from the back of the piece to the front and continued until it was in the right shape. To say I was surprised it worked that well was an understatement.

I tacked it into place and began attempting to weld it in place. While not a perfect job, I think it will work and will keep the water out of the truck. I welded both the inside and outside of the patch. This was mostly in a vain attempt to make it a water proof solution. I know I’m fooling myself that it is.

So the final step in the fender repair well will be to give the entire underside a healthy coat of bedliner. I will do this on all four corners once I am done with the repairs.

I am still trying to source the bed panel. There are some in England, but I haven’t found one on this side of the pond yet. I have a Facebook contact that might do a bulk purchase and have some shipped over. I am hoping this works out. I am pretty sure I could order the panel and the support pieces but the shipping is ridiculous. Like, more expensive than the parts.

There were some issues with the video. The sound decided not to record on two sections. No camera changes were made…just no sound. I did a voice over for those sections. Also the shop was too hot for the GoPro to work and after two segments it shut down. I stuck it on the portable air conditioner to get it back to operating temp twice.

There are the last two sections for this fender, the “big hole” and “the strap” as I am referring to them now. Once those are done this fender is COMPLETED! Progress will have been made!

Shoppe Clean-Up and Mower Repair (Post #617) July 31, 2023

Broken Mower Part

No Land Rover content this week. I started the weekend trying to get the chores done first. Mowing the grass which grows at a ridiculous rate due the the wet July we’ve had. I’m cutting grass every week now.

I got on the mower and got my book on tape going [Extreme Measures by Vince Flynn the eleventh book in the series]. I kept hearing some odd noises, vibrating parts, and the engine was running like crap. Just last week I was evaluating how many more summers I might get from this mower while I was patching the holes in the tires with plugs.

I have been impressed at how trouble free this mower (Husqvarna 1842) had been with this being the sixth summer. I’ve only had one other serious repair. It was also a mandrel. I have also replaced one battery and before the summer is up, I really should replace all the tires.

After an inspection I saw the shaft on the mandrel wiggling like crazy. The upper bearing failed on the mandrel. So it wasn’t going to be grass cutting for the weekend, it would be mower repair. I looked the part up and found it had a John Deere part cross referenced. I went down to P&K Tractor on Highway 9. The parts guy was SUPER helpful. He looked up the part on several sites and found a part number at O’Reilly’s. Turns out in his words this was the most common bearing in the world. I was surprised how many different parts numbers were associated with it. I ran down to O’Reilly’s grabbed two.

The bolts (steel) were really stuck in the mandrel housing (cast aluminum). You don’t have to be a chemist to know this is a recipe for disaster. And that’s exactly what happened.

I wound up having to attempt to drill and easy-out what was left of the bolts. Broke two drill bits and eventually the mandrel. Four hours lost. I’ve ordered a replacement, it comes in this week. So I spent the rest of the day cleaning and organizing the shoppe.

I’m going to visit an old Marine friend of mine this week. Jeff was one of my closest friends in the Marine Corps. We went to boot camp together and artillery school. I haven’t seen or heard from him since perhaps 1988. Gonna be great catching up. RovErica’s kids are coming to stay with us this week too. With all this happening I don’t think there will be any video next week. But we’ll see.

Jeff and Bear
Heavy sigh.

Fender Prep the Mud Flap Post (Post #614) July 9, 2023

Mudflap Removal

In this installment of me removing rust I work on the mud flaps. They were in the way of me grinding the rust spots in the wheel well. So I removed them, and good thing I did. The driver’s side (port side) mud flap steel was nearly rusted through under the flap.

The pitting was impressive and the amount of rust stuck on the flap was amusing too. So instead of welding my rust holes in the wheel well I had to take a day to fix the mud flaps. I went ahead and did both sides. The passenger side (starboard side) did not exhibit the same amount of rust as the other.

I got them cleaned off and applied the Duplicolor Rust Preventative to them. This is the stuff that is supposed to take surface rust and transform it into “not rust”. Through the magic of chemistry this “paint” converts the rust to I’m guessing zinc? hell I don’t know I got a “D” in Chemstry 1 and Chemistry 2 at the University of Oklahoma. In my defense, I drank more than I studied, and I had a nearly full-time job, and served a weekend a month as a Field Artilleryman in the USMCR.

Whatever, it’s magic and I’m not likely to do that job again on this Range Rover. Once I’m ready to reinstall them they will also receive a coating of rattle-can bedliner/rhino lining/stone seal or whatever they call this stuff in other countries.

The week had a lot more work done and filmed but I’ve run out of time as it is now Sunday. I’ll post another video this week of the rust cutting and removal under the fender well.

As we say here in Oklahoma, my hands and knees and back hurt “something fierce” [Merriam-Webster]. I haven’t done this much wrenching/grinding/hammering in at least a year. I ain’t gettin’ any younger so I gotta play through the pain.

Grinding makes me happy.

Fender Prep and Planning to Weld (Post #612) July 3, 2023

Me looking back at the camera.

In this installment I talk about how I will attack the rust in the driver’s side rear wheel well. I bought some shielding gas for my mig welder and will be welding patches and fixes this week. My GoPro camera decided not to record audio on the underside review so you’ll have to settle for a lovely voice over (which is terrible). You’re welcome.

Hope you enjoy the content. You can contribute to help with the cost of keeping this site on the internet through my Patreon account.
