Looking for pics/links to some custom audio installs in a 928. specifically any that use horns (or waveguides) like these:



Also would like your impressions of the overall soundstage presented by the factory speaker locations. The rear cargo comp. speakers are useless IMHO, but the rear quarterpanel location might provide a good midbass location. Anybody got a pic of what's behind the rear quarterpanel speaker location? Is there room to seal it up?

I've got a Nak CD-35z waiting to go in the dash of the 928 I buy and can't wait to get started. Subwoofer enclosure design should prove to be interesting

Just one point - the rear cargo quarter panel speakers are there primarily for the rear seat passengers and not occupants of the front two seats.

From that picture you show, the owners feet should be very happy. Too bad your ears aren't on your ankles.

I can't imagine a better location for speakers in an auto then the stock location. The bottom of the door has a lot of room for a custom bass enclosure that may even accomodate a sub up to 8 inches.

If I ever get to the frivolities of a sound system (tons of mechanical stuff to do first) that's how I'm going to do it.

Most people don't know what soundstage is. You may be scaring some members of the group. I've had people tell me their car had great soundstage and they had the trophies to prove it. When I got in the car, the voice was coming from the back seat. Never sat at a concert facing backwards before...

I've had cars that sounded better with kicks and some the sounded better with speakers in the dash/doors. Depends a lot on the layout of the interior. I can always try the stock locations first, then play around with it at a later date. The main reason for putting speakers in the kicks is to get more distance between your ears and the speakers, but it's debateable .

Most vehicles are not suited to waveguides, but the 928 looks like it was made for them. With horns under the dash and mids in the stock location, It should sound very nice. If you've ever heard a car with horns in it, they dispurse the sound very nicely. They don't sound like they are under the dash, but rather IN the dash if they are done right.

In the 928, you sit low and back from the dash. This means that the stock locations are just below ear level (at least on me, 5'10").

Didn't mean to scare anybody. My current setup in my Cherokee has 6 speakers up front and one sub in the back. No rear fill at all and it sound superb. Tweeters in the dash, mids and midbass in the doors. No room for kicks.

I wouldn't go so far as to put a sub in the door, although that would be interesting. The space is so small inside the car that a single 8 or 10" sub in back will sound like 2 12" subs in a sedan.

I just installed an Eclipse Dolby 5.1 system in a friends 87' S4. It came out sounding beautifully and looking good. He has a box custom made to fit behind the rear seats and include 2 10" Extant subs and hold the Fosgate 800 and Pioneer amps as well at the DTS decoder and disc changer. (He's young and it eliminates any storage area) The AM/FM tuner fit in the old amp location beside the passenger seat and the DVD on the passenger side package tray. It has the 5.8" display that folds up into the dash. He has 6.5" 2-way's behind the doors and 4" 2-ways in the doors and far rear panels with a center channel speaker behind the center A/C grille. He needed full range sound on all points for the Dolby, that's why the speaker selection. (Still looking for a TV tuner and GPS) Unbelieveable sound and imaging!

My 86.5 has a Blau Tokyo deck with a 10 disk changer, Cerwin Vega mids and tweets in the doors and Orion 6.5" mid bass behind the seats. I made a custom box (9 sided!) that fits perfectly in the spare wheelwell with a 10" Audiobahn sub. I am currently building another box to fit a 12" Audiobahn Alum sub. Plans include a false floor to cover the amps and sub and look totally stock behind the seats. At the moment, I am using an Alpine 4 ch. amp for the mid bass and doors and a Sony amp for the sub, but that will change to a Fosgate amp with the 12". I may try out the Memphis Belle amp in the near future. (4 ch. @ 135 watts, class AB, and 1 ch. at 1000 watts, class D.) My car has almost too much sound, but I want too much! The "soundstage" and imaging are very good in my car, but could be better after listening to my friends DTS system.

There is no limit to what can be done, as mine can be returned to totally stock as can the 87'. Speaker selection is critical due to space restrictions. I may also try the Audiobahn component system soon. They have a 3-way setup with 6.5", 4", and tweets with crossovers. (Part # ABC6003Q) They may be a bolt in replacement for the stock speakers, but requiring additional wiring for proper crossover operation. You will need to mount the tweets angled toward the passengers. The 4" speakers in the back do aid in the imaging, but only to a limited degree.

Long enough post? My car is in the constant upgrade mode for audio. I'm never quite happy, and may end up with a 7" touch screen, GPS and DTS system of my own someday soon.

It can be done! If someone would like pictures, e-mail me with a specific request and I'll try to help you out.

I have a 1990GT and i took my spare and turned it over then i used the hole to mount a large sub woofer in the pit of the tire worked out great and looks good too

User 4221

Hi Jim,

Do you have photos available of the spare tire install?

Additionally, what size sub did you use?

Thanks,
Scott

I have a 10" sub installed in mine. I also run 2 Kenwood amps (a 500 watt and a 300 watt). The rest of my speakers are MP Quartz and in place in the original speaker mounts. I do not have the sub set for the kiddies BOOM BOOM, I enjoy hearing the high's , mid's, and the low's. I enjoy my music at times, but admit my system is very clear even at the loudest out puts.

Big Dave can atest to the clearity of my system.

I will post pics of the sub tomorrow, or I can send you one.

Ketchmi, if you have any pics of your friends install, especially the sub enclosure, please email them to me or post them here. Also, the 9-sided sub enclosure as well since that's probably the route I will go.

How hard is it to remove the back seats? And what's under there? Was thinking that removing the back seats would allow for a dual sub enclosure (split down the middle) and amp rack without eating up rear cargo space. Could easily be removed and the rear seats put back in. Hmmm, got me thinking there Ketchmi.

currently I am running a 3way compnent set I pieced together from 2 Soundstream Exact component sets. 1" tweets, 4" mids and 6/5" midbass. I'm driving each speker individually with the crossover action being done by an AudioControl 4XS. I've also got an AudioControl PHX in there to widen out the soundstage, the Jeep feels so confined. Amps and headunit are Sherwood 12-Volt series (35 x 5 and 100 x 1)(2 of these) and the sub is an Alpine Type S 10" DVC with each voice coil being driven independantly. It's in a .9 cuft sealed enclosure. My system sounds awesome and gets fairly loud, but it's not a boomer system, rather an SQ system.

I removed the center channel and surround sound processor, but everything else is there.

With the foam on the bottom of the spare tire cover all you have to do is add 1/4 or 1/2 inch plywood over the top of the cover, and seal it. this gives you a real tight sounding sub. My sub is a 12" autotek

KBlair

Autotek makes some nice equipment. I've got a 3-way Autotek crossover that I've never used. their subs are tight, and reasonably priced.

Weissach

Have a look at this...

Hi Jim,

That is exactly the route I had planned on taking.

I am assuming that you have retained the spare and are using the sub in a "baffle" arrangement. In other words, you can still use the spare tire if you need.

So, if I understand it correctly, if you lift the board, you will see the subwoofer magnet frame underneath and not an enclosure?

Thanks in advance!

Yes the spare is still useable, I let the wheel well work for the enclosure, make sure you seal the sub to the plywood and you will have a fairly air tight seal, that is if your original cover has the same foam that mine does

dshulik

I like the craftsmanship shown in all the above pics....very nice!

If you're not planning on spending major $$$$ on customization you may consider how I had mine done.

I went a fairly simple route with my sound system and had an Alpine 10inch sub in an Alpine cabinet set behind the rear seat which can easilly be disconnected if cargo space is needed. I can also fold the seat down and simply move the cabinet forward over the seat for added space. Believe it or not, I was able to fit my mountain bike in there a couple of times (plus about ten towels to keep things clean. A few cuts were made in the lower door panels for 5 inch speakers and tweets in the upper door panel where the factory speakers had been. In the rear below the seat belt reserviors I have an assembly made by ADS which hold another mid and tweeter.

I run a passive head unit from Alpine CDA-7995 that has all the goodies like MP3, XM sattelite, controls for different crossover frequencies, detachable face, remote control etc.

A 400 watt amp drives the sub(a cheapie..by Boss)but does the job just fine. A Precision Power PCX440 amp running a very clean 165 watts or so drives the mids and tweets with perfect clarity. The amps are located much like the photo above to get good ventilation but they're flat enough not to get in the way if you have luggage or hockey equipment. I really don't know where the heck else they could've gone.

I'm extremely happy with the sound and I lose virtually nothing in terms of cargo space except for the box holding the sub woofer. The Alpine head unit has all kinds of settings to control delay for each channel independently, so you can get pretty much any sonic effect you want without having to be too concerned about speaker location (my opinion only of course..I don't work for Bose or anything like that).

With the rear cargo cover and tinted windows, nobody can tell anything special has been done...good for keeping theives at bay.

I'd certainly consider doing the integrated sub like above but I think I'll save that one for my GTS whenever I can afford one.

Great jobs on the the integrated sub and the in dash monitor...they look great! <img src="graemlins/bigok.gif" border="0" alt="[thumbsup]" />
