Can anyone tell me if there is an amp in a 94 intrepid with the Infinity Sound system and if there is where is it located?

Also how many watts can the rear 6x9's handle, I have a 50X2 channel amp and I was wondering if it would be too powerful or not powerful enough.

I dont know about the factory 6x9's but most 6x9's have like a 100 to a 140 watt max on them, the 50x2 will probably anhance but u can go more but be careful with 6x9's and pushin amps on them cuz if u hook it up wrong BOOM there gone!

Ok, first off some facts...or rather some very good theories put together by some car audio specialists. Believe me, I've asked. Ok, first off, the amp located in the trunk (left side, behind the carpeting...think spare tire) is putting out only about 15W RMS, maybe 20W. Stock head unit may put out about 2W, if anything. Next order of business: the stock speakers are all paper cones. Putting any more than 50W RMS into those would be ill advised, not to mention a waste of time. Those stock speakers can't take advantage of it. I'd say those stocks can handle only about 50W RMS, but I wouldn't push it...especially on an 8 year old speaker.

I think it is located kind aby the taillight, left side. Pull back the carpet and you should see it. From what I am told it doesn't have the "typical" amp appearance.

its a big metal box with wire harnes coming out of it. Its behind the carpet in the trunk on the side opposite the antenna.

the stock amp is located on the drivers side in the trunk behind the carpet it looks like a silver amp with 3 mounting screws holding it in place. as for the stock speakers you wouldnt notice much difference with a new amp just a little louder but what kills a speaker is lack of power and people turning the music up to get more volume. with more volume comes more distortion and that is what will kill a speaker. i would sugest replacing the 6x9s with after market thier sound quality will be so much cleaner and better sounding. but remember always try speakers at a quality store and buy what sounds good to you not just what the sales man says is good. a few good brands i use in my car are kenwood, alpine,kicker and rockfordfosgate. you can actually achieve a fairly decent sound with the stock infinity amp and some replacement speakers. another concern you need to have when running stock speakers is what thier OHM rating is and wether or not you amp is stable at that rating or is it gonna sttart clipping or over heating ect...... some of the common ratings for an amp to be stable at are 2,4 and 8 some are stable down around 1/2 ohm to 1 ohm but this is found in the more pricey amps. lower ohm loads ussally equal higher volume but with less sound quality. by talking to some shops you can find what fits you and the best way to hook it up. there is alot that can be done in these cars not only to have a decent spl level but also a nice sound quality. I myself have 11 speakers in my concorde with good sound quality and imaging all run off of 2 amps. hope my blabbering helped at least some lol well happy deafness at any level............

Thanks for the info, I was thinking about replacing the speakers all together, but the rear 6x9's are pretty good, they only get distorted when the bass is turned up. I figured that they're just underpowered.

any thoughts?

Also, isn't it a lot of work to get to the 6x9's? I heard people saying you have to take out the whole back seat. I'd rather get it done somewhere than mess up my seats. As for my amp, I was hoping I could just switch the wires from the stock one to mine, but then I remember that the stock system probably doesn't come with RCA inputs to go into my amp.

any thoughts on that? (other than re-wiring my whole system)

Who knows, I might just replace the door ones too at a custom shop once I get the $$$

Replacing 6x9s

According to Crutchfield's "MasterSheet", replacing the rear speakers does require a torx driver and a bit of patience because you will be removing the rear seatback. My only concern is the extra pair of leads attached to the speaker baskets on my 6x9s. I don't know what the hell they're for, much less what to do with them on a new pair of speakers.

As for that distortion you hear when you turn up the bass, it's probably the door speakers that you hear. I know what your talking about...it's a very flat bass "thump" and it's caused by speakers trying to reproduce sounds they weren't designed to handle. For that problem, you'll need a crossover, or some bassblockers from Crutchfield. The bassblockers are a cheap method, but you won't be able to change the frenquency cutoff, as they come preset. Amplifiying the signal will make this problem worse. The guys that I've spoken to at Tweeter, Circuit City, and Custom Auto Sounds tell me that I should get some decent sound from the factory amp and my Pioneer head unit just by upgrading the speakers. I'll have to try it and let you know what results I get. Hope this isn't too much information all at once...LOL!

BTW - The amp is marked "Infinity Spatial Imaging"

you can atually remove the rear deck by removing the two side beauty panel and prying it up and out. it is easier to take the back seat out!!!!!! much cleaner then prying the deck out. the bolts are in the center of the seat follow the seat belts down.it is real easy to remove and put back. if you are using a stock amp a electronic crossover would not be desirable. better off if you are gonna keep the stock amp in line is to get some passive crossovers" bass blockers" you can get these at best buy or circiut city or just abpout any good audio shop. all they really are is a cap that allows them only allow certian freq. to goto the speakers. if you can find out what the rating for the caps are you can actually at radio shack. some where i have a list of caps and frequency cut off points i will try to find it and post the info. another place to try if you want to buy them online is to go to www.partsexpress.com any part you could want and THEY ARE A HELL OF ALOT CHEAPER THEN CRUTCHFIELD. as for the two wires on the 6x9 that im not sure of but i do know when i was still using my stock amp i used i believe the two outside wires. the stock infinity amp is amazingly good quality for a stock amp. the biggest difference is you will have alot more ability to adjust the sound of you music and alot of good quality after market amps have a crossover built in. also alot of your better head units will allow you to run rcas or preamp outs and speaker level outputs at the same time. if you decide to put in an aftermarket head unit do your self a favor and buy an install kit and wiring harness adapter when you get the wiring adapter it will give you the color codes to match up. as for the coloring code of the stock amp i can try and find that also i had a copy of it from a friend of mine who is a professional installer. as for tracing them dont bother man they change colors before they hit the stock amp.

I know about the distortion in the door speakers, they're just horrible.

The rear speakers just start distorting when I turn up the bass, I can take it up to a certain point and it has amazing bass for 6x9's deep too, but it doesn't get louder without distorting.

About the extra wires, I believe there's a tweeter built into our 6x9's, that's why there's 4 wires instead of 2. I tried hooking up other 6x9's (without putting them in the car, just changing wires) and I either got pure bass, or pure treble. I dunno, maybe I did it wrong.

there's a thing called a wiring diagram they make. this seems to me like it'd be a good time to try one out. :sly:

 

[Black94ES]

Where can I get one?

As Blacky said, please tell us where to find one. I've tried Dodge, Infinity OEM Dept, some pro audio shops in the area, but none of them seem to have one for sale or otherwise. Thump, you seem to have some connections...think you can find one for us?

 

[thump186]

i believe metra is the company that the installers can call and get the diagram. if you can find one thats not lazy. if not i believe circiut city and best buy has this info on computer. if not i will see what i can get may take some time but i'll try

 

[1mz-fe]

the chrysler Service Manual has one.

 

[stevedemon]

the chrysler Service Manual has one.

I had a feeling it did, but I understand those things are pretty expensive, and the Dodge dealerships don't sell them. You have to call the company that puts them together...the name escapes me right now, but I know they gave me the phone number when I called Dodge parts. I guess it's the same one they use in the service dept. Not really interested...those things are all greek to me. I'll keep my Haynes manual, TYVM. :biggrin: Nice thought though...
