If you go with 4 gauge power wire then the ground wire must be at least the same size as the power wire.

 

Absolutely. I'm an electrician, this is absolutely right. Mixing the gauge is unsafe and could cause a fire.

 

mine is having the same problem, but the amp is not over heating. It turns on for maybe a millisecond, then just turns back off. hellpp!!

 

What's the fuse rating on the amp?

Honestly, if you're running a single amp, you *should* be fine on an 8awg wire, unless you're pulling some serious current.

Make sure you've got a good clean ground going to the chasis, all the teminals and connections are clean, etc.

greekfreak - might be something with the remote turn-on wiring from the HU to the amp. That sounds like its sending a pluse instead of a constant 12vdc.

 

sounds like a short or a bad ground. check your fuses too

 

it could be a bad ground also man but yea usually its cause your amp has a protect on it and its stoping you from blowing your subs
