On my LPE I am going full aftermarket. I am going to try and figure a way additional speakers as the current configuration is horrible. When I am driving long distances I have a habit of putting my left calve over the front speaker.

I'm kinda favoring just building a really good aftermarket system at this point, my main issue with that (besides being expensive) is trying to find a good spot for an amp or amps. Looking at putting an 8in sub in the drivers side rear storage bin so no room for an amp there. I could put something in the passenger side rear storage but I don't want to clutter it up too much, like to keep at least some storage space there. Wouldn't mind putting an amp at the very bottom of the bin but its only 8x8 and about 3 1/2in tall. Not finding much that fits in that space. Also concerned with heat, amps tend to get hot so I don't want to pack one in somewhere only to have it get cooked. Guess thats the nice thing about the independent Bose amps, they don't kill your interior space.

Build an L shaped box where the amps are inside the horizontal fixture. I have been thinking about this for years. M&K utilizes a push/pull box where the rear wave of a second sub is open. The wave when it exits the sub will move air across the amp. I can draw you a draft of the box if needed.
I have Bose 901 and a M&K X12 that are over 12 years old in my house. I have tried to upgrade my home sound system twice now and cannot match the sound quality.

Locobob,

I built an extensive system back in 91 for my 91 ZR-1. Although technology has marched on, one major difficulty I encountered back then still is valid. Main challenge was front speakers. In order for any speaker to produce good low to mid frequency is to be in an speaker enclosure and our cars lack any place for decent size enclosure. Fabricating a MDF plate and throwing a speaker on it really won't do anything. Factory front speaker enclosure was custom designed by Bose and tuned port was optimized for the 3" Bose speaker. As such, considering that it's 3" speaker our front speaker/ported enclosure produces pretty good sound. I used the largest after market speaker I could fit in the front OEM enclosure but never could produce level of quality OEM set up has. Rear is not too difficult.
Second time around with my 94, I replaced the head unit, spliced into OEM speaker/amps and added an amp and 10" low profile sub-woofer to augment low frequency. Dealing with limited speaker/enclosure space in the front of our C4s, I am convinced the route I took is about the most optimal solution - just my 2 cents worth...
For the alternator whine, try my capacitor trick. It less then 10 bucks and 15 minutes to install - and it won't blow up an alternator. Don't replace the whole system because of the alternator whine. This noise is not coming through the electrical wire but rather in radio frequency from the alternator. That's why relocating ground and re-routing wires won't solve the problem. I chased alternator whine for a year and rewired the system 5-6 times back in 1980. I know how frustrating it gets.

Link is to a webpage explaining how capacitor eliminates alternator whine, in this case, in aircraft communications head phone - similar to whine coming from speakers.

I just ordered a noise filter, going to try that first. I'll read up on the capacitor idea but it makes me nervous as I don't know anything about it and Dr. Don mentioned something about car fires.

Making some progress:

Managed to fix the headlight switch illumination issue... ended up using amber LED's with the factory bulb condoms for the backlights. The traction control button is a little extra bright with the LED I used but no biggie - currently this button is unused as my car is a 91 but I figure it may come in handy to have an extra button some day.

Center console devices are working great.

The stereo still has some alternator whine, I think the filter helped a little. I'm just going to live with it for the time being, lost enough of the driving season already.

Yup, that's going to be it for a little while, gonna drive it!

Next up will be the center console and door arm rest re-upholstery - probably in a few weeks. Seats will get done in a couple of months most likely.

Looks great!

Did you ever find a source for the clips behind the radio bezel? I need one of those too ...

Robert,

this link has a lot of images of my install.. many at the end are the tablet install I now have..

Might swap back to the App Radio.. Still working it out on the Bench
