well after much hard work i think i have finally gotten the stereo upgraded in the 996. after trying some mb quartz and bowing them i went to diamond audio and got a 3 way setup from ebay.....

they had a "true" 4.5" speaker, rather than a 4" speaker like everyone else sells. The mounting ring was slightly larger than the previous 4.5" so i had to trim it off slightly in order to make it fit.

the tweeter was also larger than the 1" pre-existing tweeter, (more like 1.75") so after some trimming, i have gotten that to fit....

and of course the mid base speakers were 6.5" not 5.25 like the stock ones (actually measured out to 6.8") so a LOT of trimming on the stock box i got that to fit....

i also have made 2 fiberglass enclosures for 2 10" sub woofers and it is all being powered by a 450/4 jl audio sub and a 500/1 jl audio sub....

after all this work i would defiantly say there is a HUGE improvement in sound, probably the best stereo in a car i have ever owned......

wouldn't recommend this setup to anyone who is scared of modifying the speaker baffles or stock woofer boxes but if you are a better stereo is very obtainable

will follow up with pictures tomorrow.....

 

here are some pics, if you are wondering where the amps are they are behind the spare tire! as you can see the diamond audio is the same size as the stock one, just had to trim the mounting rin to get it to properly fit

 

dude, those are some serious speakers. i bet it sounds great.

 

where is your amp? or is your headunit driving that?

 

i have a jl audio 450/4 and a 500/1 behind the spare tire, you can see the corner of the amp sticking out behind the spare...

 

Great post, thanks for sharing... I am also looking at upgrading my speakers and recently posted on Rennlist for suggestions.

 

here is a picture of the subwoofer before i covered it in carpet....just to get you an idea of how to get a sub in a convertable...it is a 10"

 

Do you have the stock head unit...i was thinking of amping my stock system...they are decient speakers i think some more power will bringthem to life...

Was the amp install as simple as splicing wires and reading the wiring diagram??

I have an MTX 7500 10" in one of my other cars...with 3 amps...im thinking of taking that system apart...and puting parts of it in the P-Car

 

Nice work!

 

i replaced the head and ran all new wires to all the speakers, i didnt want to cut any of the stock wire harness.

the mtx is probably too deep for where i placed them unless you want to replace the back seat.

i used a 10" pioneer speaker that was only 4" deep.

the stock speakers cant handle very much power unless you cut the frequency off fairly high...then you HAVE to have the sub...

 

ya im thinking of replacing the stock amp with an upgraded one...direct plug in...then the Traffic pro which I am installing has a sub output...so i will have a seperate sub...Im going to try my MTX under the front lid...its currently in an S class Benz in the trunk and still rettles my brain.

 

i haven't ever tried mounting a sub under the hood but i know others here have and said a you get is rattles and no bass.....

unless you build a bass port that ports into the cabin

 

Do you have any pictures of mounting the 6.5" speakers on the factory door enclosure that you trimmed?

 

Very nicely done- Bet that was a lot of work.
Are you going to cover up the wires and xovers in the trunk area?

 

sorry i don't have any pictures of the doors, i need to take them back out to plug up the vents so i will get some in a couple of weeks......


the wires to and from the crossover have been cleaned up, i need to get a strip of carpet to conceal the single bundle that goes to the amps
