Hi I have a problem and have been unable to find any suggestions on what my be the cause.

My Car:

2005 Dodge Ram STD

My Audio:

I have 2 Infinity Amps

REF611A 600 Watt Class D Subwoofer Amplifier

REF7541A 520 Watt 4-channel amplifier

REF611A is pushing 2-10" Kappa Perfect in parrallel

REF7541A is pushing 2-6"x9" Diamond Audio & 2-5-1/4" Kappa

I am running 4 Gauge power with 80 amp fuse from battery to a distribution block that splits to 2 8 guage with an 80 amp fuse that go to each amp.

My Problem:

The distribution block heats up on the 4 channel side both the wire and the plastic around the block connection melted. The fuse was so hot that the glue holding the nickel caps on the glass melted. I replaced the block and removed the bad length of wire. The fuse gets really hot at max volume after 2 minutes. The sub side stays really cool. Any Ideas???

You have some sort of short on the 4-channel amplifier side. You may need to have it serviced. Does it work otherwise?

Also, are you clipping it like crazy? Why are you running at max volume for 2 minutes?

The amp works fine otherwise. It will cut out a few times. I listen at max volume :) Do you think their is an internal issue with the amp??

1st thing I notice is 80 amp at dist block, this seems high for 8 gauge, the fuse should blow well before melt down...It appears your 4 channel needs more current than can be supplied with an 8 gauge wire. Is your output/watts listed rms or peak. If rms you will need to invest in larger gauge wire, maybe 2/0 or o gauge, then distribute down to 4 gauge...

Bigger wire on the amp for power and ground is a must. Make sure that there was not also a small shard of wire that may have been making contact with the mounting screw on the distro block.

Melted wire and/or distribution block = result of an installer who should not be working on your vehicle, and you are lucky you didn't burn down with your car.

Listening at max volume = system is too small and blown speakers are on the way (along with being deaf.)

Sounds to me like you need to spend some money and get assistance from a local pro.
