keep popping fuses
Hey guys, I gotta question. I am doing my install and I've gotten to the final steps.
Everything is installed and wired. This is a noob question, I know, but why do I keep popping fuses. I have done everything correctly. And everytime I go to hook up the battery I pop a fuse.
Here is my setup:
Power
4 gauge from battery to cap, fused at about 12" from battery.
4 gauge from cap to power distribution block
8 gauge power from dist. block to both amps.
Ground
4 gauge ground from cap to chassis
8 gauge ground from chassis to both amps.
I am at my wits end. I've followed direction after direction.
It may be simple,
but all I know is I need help.
Thanks,
Tim

We need to know what fuse is popping. I assume that it is the one by the battery, but there is also fuses on the amps, fuses for the headunit, and some dist. blocks and caps. have fuses also.
only thing that I can think of off the top of my head, is to check and make sure that the positive wires are not pinched somewhere and grounding out. also, double and triple check to make sure that your wires are hooked up correctly on the cap.

1). It is the fuse at the battery that keeps popping.
2). I scraped the paint off of the grounding point to make it bare metal.
The grounds are good and tight.
Would it make a difference that I used separate ground for each amp?? I chose to do it that way for a shorter wire run.
One thing I did notice when I went to connect the ground to the battery it didn't pop the fuse until the head unit started beeping. (My head unit beeps, as does the door alarm when the battery terminal is reconnected).
I am using a 60 amp round fuse. Or would that matter?
My amps are a Punch 401s for the mids, (100x2 @ 4 ohms),
and a Punch 500a2 for the sub. (500 watts x1 @ 4 ohms).
I'll go back and check the conncetions at the cap to make sure they are correct. My cap has an alarm for reverse polarity, but I'll check it again anyway.
This is really bugging me I have installed several stereo'* and more than one amp and I never had this much aggravation.
Thanks gang, for all the help,
Tim

do you have a electrical multitester? that would make this much easier, and cheaper, so you don't have to keep blowing fuses to see if it is right.
if you have one or can get one, set it to continuity and test the main power wire against the ground. it will probably indicate a connection which is why you are blowing the fuses.
take the power wire off of the cap. and then check for continuity, if it still says there is a connection, or if the fuse blows again, the main wire is pinched through the insulation somewhere causing it to ground out and blow the fuse.
if all is good, then continue on down the line disconnecting each part of the system and testing again. this should help you narrow down where the problem is.
also, try disconnecting all of your grounds, then test it also. this will check to see if there is a problem with your wiring, or the equipment.
any other questions just ask

Hey guys, thanks for the tips. I got it up and running last week. It was a rather noob mistake on my part. But it was quite easy to fix. It turned out I had an amp wired wrong.
Thanks,
Tim
