Im running into a couple of problems after my recent car stereo install.

Pioneer 5900iB HU
Infinity 6020cs components w/ crossovers
Phoenix Gold 9.0.5 amp
Alpine 1042w sub

The wiring was done based on whats posted here. Power on the drivers side, rca's on the passenger side. I ran Front, Rear and Sub RCAs, although there are no speakers attached to the rear channel.

Here are the issues Im running into:

Electrical noise. When the engine is running, there is feedback through the speakers. If I shut down the engine, the noise stops.

Sub channel is blowing fuses. The first day I had the sub in, I noticed it had shut off. Ends up the fuse for that channel had blown on the amp. With the car turned off (so the stereo system is off) I tried plugging in a new fuse and got some major sparking. Im admittedly green in the stereo department, so this may have been an obviously stupid thing to do. I pulled the positive battery terminal and replaced the fuse. It blew again after reattaching the positive terminal.

Ive already checked the power wire. Its attached well at the battery terminal and the inline fuse seems ok. The power and ground also seem to be attached firmly on the amp.

Any suggestions of things that may cause either or both of these issues would be appreciated.

 

Do you have 2 fuses inbetween your amps? One from...power line from battery to fuse-box, then power line towards rear of car into a fuse box/ and or distribution block with more fuses?
This should maybe keep your amp fuses from blowing, but i could be wrong.
Make sure everything is hooked up before putting the fuse into the fuse-box just before the battery. It should be one of the last things you do.

If you have noise...maybe try seperating the RCAs from the speaker wires. Like have the speaker wire running down door sill, and RCAs running down center console area. Also, for the RCAs not hooked up, put some electrical tape on the ends to keep them from getting a signal.

Actually...if you haven't done that yet(elec tape)....do that first, and see if it works. Thats all i can think of, but im sure other people can help you better than I.

 

No. The power wire comes off of the battery terminal, runs into a fuse, and then runs along the passenger side of the car and eventually connects to the amp.

So, just one fuse, and it does not go to the fuse box.

 

Update .. the amp is fried. I cleaned up the amps ground point, plugged in a new fuse and got a loud pop + smoke out of the amp. I replaced it with a Pioneer configured for 3 channels, and there is still some feedback in the door speakers when the car is running. So, the sub is back online but I still have the electrical noise issue.

 

what do you have it ground to? it could be a bad ground.

 

you dont want to run the power wire down the passenger side. more wiring over there which creates noise. Power wire down driver side, speaker wires and RCAs down passenger side.
And there should be a fuse block and distribution block with fuses between the amp and battery.


from batt to fuse block


Wire on right will go to driver side and run along door sill to fused distribution block in rear

 

Sorry, not sure why I said passenger side. In my original post I said the power is on the drivers side and that is correct.

There is no distribution block in the back because the power only runs to the amp. Why does it need 2 fuses? Im not following on that part.

The ground is connected to what appears to be a rear suspension brace.

 

If anyone else has a suggestion, that would be great.

 

Where did you get your RCAs? If they are ghetto, then that might be part of the reason...

Also make sure that they are designed for use in cars, as those are going to be insulated more and able to withstand the heat better than ones designed for home use...

 

If you think your ground is good, use some insano speaker wires and some real good RCA;s
