re-check your wires if nothing is loose.

each amp is bridged to 4 ohms so theres no problem there with the ohm load

ok so i found out the problem.....i melted my main fuse it didn't blow for some reason???? i am running an 80A blade fuse so my new question is do i need to run a bigger fuse or something different??? i am running 2 800watt amps

What size of wire are you running? What size fuses does each amplifier have? ------------- There are 3 kinds of people in the world, those who can count and those who can't

Don't let the smoke out of your equipment, you can't put it back in.

heres my setup hope it doesn't confuse you guys battery----4 gauge----80A fuse---4 gauge--------cap-----split into two 8 gauge-----amps

You would be safe to fuse the 4 gauge wire at 150, however, you need to fuse it at the total current draw on the wire (both amplifiers). For example, if each amp is fused at 40 amps, you would need an 80 amp inline fuse; if both are fused at 50, you would need a 100. What is each amp fused at. If the correct fuse blows, it means you have a short somewhere. ------------- There are 3 kinds of people in the world, those who can count and those who can't

each amp is fused at 30 i just went out and bought an ANL 150 fuse do you think that it would fix the problem

Explain what you mean by "melted the fuse"- is the metal conductor broken or did the plastic melt? If the plastic melted, then it's too close to a heat source- relocate it elsewhere. If the conductor is broken, and you're unable to locate a short anywhere, I'd try the new fuse. I've seen the glass type come unfused at the ends under normal use, but not a blade type. Let us know how it turns out. ------------- My ex once told me I have a perfect face for radio.

You need a 60 amp main fuse. If the actual metal is melting, it means you have a short. But, like geepherder mentioned, if the actual plastic melted, it is too close to heat. It is possible the wire is grounding out or maybe an amplifier is fried. Let us know how it goes. Jacob ------------- There are 3 kinds of people in the world, those who can count and those who can't
