OK......I am fixing to rewire my system for the 3rd freakin time. Im getting angry man. Every time I change the freaking thing around, something goes wrong.

This time I dunno what the hell the problem is. I have bad grounds I know that much, I have some slight alternator noise, not horrible, but its there. The biggest problems are these:

I have "bleed thorough" (dunno how else to put it) to my sub from my components. Meaning...Ill go into the head unit, turn the sub off and it will still play. I turn the components down and the sub volume decreases. My sub amplifier gets hot as HELL at normal levels and it never even broke a sweat before. The whole thing is just jacked dude. My wiring diagram looks like such:

There are a few gimmes on this diagram, the crossovers and remote wires are not shown, but they are there.



I just dont see how the hell the sub is getting a signal from the front components. Unless the preamp is screwed. That would not be high on my cool list. Im about to chuck it all and take it somewhere, but I dont know of anywhere to take it to that I would trust with my baby. Id rather do it myself and screw it up than have a bunch of grubby, unprofessional kids with their paws all over it. I wish there was a vender on the boards close to me..grrrrr..

 

somebody anybody.

 

Your amp appears to be only stable down to 4ohm bridged. I can't find any documentation that says it's stable to 2ohm bridged. This could be over-pushing the amp and that's why it might be running hot. This is your amp, correct? http://www.realmofexcursion.com/ampg...x_Gold_XS2500/

As for the ground loop noise you seem to have, try a few different ground locations and keep them as close to the amp as possible. Where are your amps mounted? Are you using beefier sheet metal and grinding away the paint and using star washers? Also try rerouting your rca's, they may be near a wire somewhere along the path.

As for the 'bleed over', check the user manual of the headunit to see if the sub out has a "sum" or "combine" mode. If it does have something like this, it takes a sum of the front/rear outs to formulate the sub information. This could cause the issue you describe. If it does have this feature, turn it off.

 

Nope, no sum mode. I dunno what the Eff is going on. I guess I'm just going to have to strip the whole thing back down and rerun the whole thing. I may just go ahead and get new preamp leads from the store and start from scratch. Its weird tho, everything was working fine before I rewired it, and I didnt change a damn thing.

 

Alternator noise is usually caused by your rca wires running next to your power or ground. Your ground should be attached to the body of the car somewhere down to the metal (if there is paint or coating). And make sure that you wired your amp and sub the right way according to which ohm your sub can handle. And it kinda sounds like your rcas are backwards. If your turing down your components and your subs volume decreases then maybe you connected them vise versa.

 

Rather than use the sub out use the rear output on the deck. That way you can fade all the way forward and no sub will play.

I do this on my eclipse deck.

As for ground loops. Make sure your ground is good. The noise is not in your RCAs...this used to be the case when head units put out really low voltages to their RCAs. Also, double check the ground on the head unit as well.
