I installed an amp in my '99 Taurus to power my speakers (no subs). All the speakers produce sound, but nothing comes out of the front door speakers when I manually fade the settings to the front via my cd player (worked prior to amp installation). I played with all settings on both the cd player & amp. I know I should just be happy that it's working, but that's not good enough for me. I'm afraid that all 4 speakers are acting as if they were all to be producing from the rear channel. Meaning, I may be missing sounds that are supposed to be coming from the front channel. Is the fade feature even supposed to cooperate with an amp? Please help me out.

Specs:
Older Kenwood deck (45wX4, 1 Set of RCA Output, will be upgrading in a few weeks!)
Infinity Reference Series 7541A 4-Channel Amp (140wX4)
(2) Pioneer 6 1/2" (220w max, located in front door)
(2) Kenwood KFC-6982ie, 6X9 (500 watt max, rear deck)
4ga. Monster Power Cable, 80A fuse
16ga. Speaker Wire

What I did:
1) Ran power cable, connected to fuse, connected to battery
2) Connected ground cable to chassis
3) Connected Remote turn on
4) Connected RCA cables to 1 set of RCA Outputs on cd player
5) Connected all to amp
6) Searched for Stereo Wiring Diagram & snipped Left front, right front, left rear, right rear wires located in trunk
7) Spliced corresponding wire(s) with speaker wire(s) & connected to correct channel on amp
8) Turned car on & all speakers are playing music. Played with settings and found out that when set to front channel only (on cd player), nothing plays.
9) Triple Checked all connections & splices & settings

Possible Problems?:
1) RCA Connection combination
2) Need new head unit with at least 2 preset sets of RCA outputs

This is IF before the splitters. They represent Left and right Preouts from the Stereo.

Also the stereo has 1 set of pre-outs. You are splitting it. you say that your change the fader on the DECK. and it actally fades? You sure you don;t mean Balance and have it hooked up with http://farm4.static.flickr.com/3529/370265...6f8a9d4.jpg?v=0"]This way://http://farm4.static.flickr.com/3529..."]This way://http://farm4.static.flickr.com/3529..."]This way

Do this until you get a cdplayer with 2 sets of pre=outs.

Thanks for everything, you cleared it up for me. Definitely going to rewire the power cable today. Why is it such a big no-no? Just wondering.

I had the RCA(s) hooked up the correct (that you said) way & tried fading it to the front on the deck. If I faded it to the rear, all 4 speakers play. Fade to the front, nothing plays. Still this way with every combination of RCA hookup. I'm still going to leave the RCA(s) the way you told me to leave it. Balance works perfectly left & right. Is this something I did wrong or what? Am I making a deal out of something I shouldn't be?

Thanks for your help, it's much appreciated.

You mentioned this is an older Kenwood.

Many decks assumed you would be bridging the internal amp and using it's power for the front speakers while running an external amp for the rear (used to be those were larger speakers with better capability to reproduce bass, a big power hog). The fader then balances the signal between the internal amp (front) and external amp (rear). As you are using only the external amp, the fader is no longer useful for you. As long as you are upgrading soon, this shouldn't be a problem for long. If you weren't upgrading the deck, then an external pre-amp fader control would restore the front/rear control. Either way, don't use the on-board fader.

FYI, there are many possible configurations using the single pair of pre-outs. This is just one possibility.

Figured out why..

I'm splitting the RCA(s) that are coming from only 1 set of RCA outputs. Therefore, my deck doesn't know what's the front & what's the rear. In the end, I need a new deck that has at least 2 preset RCA outputs. No big deal, I've been eying the Kenwood KDC-X693 deck for a looooong time.

Thanks guys :)

Correct, you need 2 sets of pre outputs set for rear and a set for front. Also you need to get a better rca cable , one with 2 left and 2 right connections. Don't split the rca cables because it degrades your signal. I'm not sure what volt head unit you have but the best you can get is a 8v deck. They're extremely hard to find and sometimes kinda pricey but well worth it. If I was you I'd look into getting a deck with atleast 3 pre outputs. Rear, Front , Non-Fadder(sub) that way you don't have to upgrade decks when you want to add a sub.
