This is the final set-up for my 12 month/$2150 stereo upgrade project.
AMP: a/d/s p840, 8 channel amp in the trunk. Channels 1-2 bridged for 120W for right front and channels 5-6 bridged for 120W left front. Channels 3-4 stereo at 40W each for 4” Boston Acoustics behind seats. Channels 7-8 bridged for 120W to drive kicker subwoofer. Amp Cost: $925 installed
40W per channel is okay.
Front speakers: Boston Acoustic 6.5 Pro series. 6 inch drivers in the kick panels, tweeters in the doors. These get about 75 HZ and above. Cost $500 installed. A MUST!
Rear Speakers: Boston Acoustic 4 inch Rally Series mounted behind the seats with tweeters mounted behind the grill of the stock subwoofer (between the seats). These get about 200 HZ and above. Cost $350 installed. Required quarter inch spacers to allow proper depth for driver. Not a Must but NICE.
Stock subwoofer: In a Florida Land Fill.
New Subwoofer: KICKER SOLOBARIC 8 inch driver mounted in a .33 cubic foot custom enclosure located in the foot well of the passenger seat. This gets 100 HZ and below. Cost: $255 installed. Needs minimum of 120W for enough warm bass. A MUST!
Pluses: a/d/s amp works hand in glove with stock head unit. No couplers or line levelers required. a/d/s amp is fully adjustable in gain and frequency for every channel. The Boston Acoustics sound tremendous. The subwoofer is VERY strong. No holes were cut in the steel of the car. Minimal loss of trunk space. System looks totally stock
Minuses: A very compact subwoofer enclosure in the passenger footwell takes up some leg room. Very expensive project.
Conclusion: It sounds incredible.
Alright, I know this has been asked multiple times, but a search through the archive didn't exactly yield the results I was looking for.
As most of you probably know the Upgraded HK Stereo in the Z3 is far from great. But with the 2000 Model year I've been having a tough time finding others that have replaced the sub in between the seats(it's a big 6" instead of two 5 1/4's, and the other speakers for that matter.
I was wondering if any of you out there have performed any modifications to your 2.3 Z's Stereo's. What have your success' and failures' been?
Currently I have replaced the head unit with an Alpine CDA-7864, and replaced the amp with a soundstream Lil' Wonder 5, also I had the whole audio system rewired with high quality 8-gauge. I've been really happy with the results(as far as clarity), but the low-end is just non-existent.
Now it's time to replace the speakers, and I need advice as to which one's have been the most succesful for you.
From what I've read in the archive, I saw one guy who placed an 8" Kicker in between the seats, in a custom enclosure, has anyone else done this? how succesful was it?
The trend for the two 5 1/4's in the footwell seems to be to buy 6.5 components, and use the tweeter that comes with it, to replace the factory tweeters. What success's have any of you had with this?
What about those 3" one's behind the seat? has anyone found any way to replace those with something better?
I'm trying to minimize the impact on the cars frame(no cutting). I would welcome any suggestions you may have!
