E30 Audio Overhaul - My Project Details

[thmpr464]

Excellent read! What was the fix for the skipping and whining noise?

I'm looking into a neat audio setup for when I finish my touring. This has me thinking maybe I should steer away from car audio (I'm on a budget) even if I haven't a clue about what's going on in here :mrgreen: I might start a thread here later as there's good knowledge on here.

Haha, thanks. I don't think it is a case of that so much as being lucky to have access to lots of tools, though (and free time). NOT owning a TV frees up a ridiculous amount of time, even when working full-time!

So, you're officially the smartest dude on r3v.

Hmm, sorry about the super late response.

I had some scraps of 20ga steel sheetmetal laying around. I snipped off some pieces, bent them & JB-Weld'ed them onto the HVAC panel at the right depth to get the CD43 flush & straight. You need to make darn sure that all oils & stuff are off of the HVAC panel plastic, and maybe rough it up with some 100 grit sandpaper to get a reasonable bond (do the same for the metal too). I also locked a nut onto the threaded post on the back of the head unit (to provide a "catch" for a zip tie) and then reached through the glove box to zip tie the post to the metal bracket back there. So far so good!

Can you please explain a little more about how you mounted this. Did you cut the side of the speaker and make a bracket or something?

True Luke. Shit what amps, besides Mcintosh, haven't been outsourced?

Just reread whole thread... why Mb Quart over say a PPI?

Both are hecho en china, why not? It isn't like the PPI is better...

Sub'd

Oh I agree. Im doing a box for a friend, and I got my eyes on that Dayton Titanic 10".

It looks astonishing for the price, specs good too

Ill have to read up on this. I always thought open air was just crap sounding. Not tight and punch at all

It depends greatly on the driver being used. Most car subs are designed for use in compact enclosures & suck hard otherwise. I didn't use any "car" drivers, anywhere in the car for that reason. A little know-how buys a lot of options.

I'd consider it more of a front-loaded baffle arrangement. The front of the sub is enclosed behind the arm rest, which is basically a super leaky damped box. The trunk is large enough, and vented into the cabin well enough that it basically all acts as one airspace.

Open-baffle arrangements have been used with great success in many home audio setups. This isn't quite one of those since one side is blocked (unless I put the arm rest down...but I can't hear a difference when I do). Either way, it is a perfectly "normal" driver configuration.

Woofer is in free-air arrangement? WTF
