yeah i know big trouble in my trunk.

4 gauge 100 amp wire kit, positive from battery, ground is no more then 10 inchs, grounded to bare metal right behind the seat that bar inbetween the trunk and the seats, o and i brought it.

i just got it installed in feburay would they fix this problem for free
i would hope so for my sakes i really dont want to buy a new amp.

is the ground location sanded down to bare metal? It sounds like the ground point has alot of resistance, which leads to the electrical voltage being changed to heat. If you have access to a DMM, whats the voltage at the amp's power terminals?

O.k. thanks for bringing it! and the first thing is you should take right back to the shop who installed it installs are usually under warranty for one year some longer, But do it fast and be like what the hell man my car is ruined becuase your guy's install!...If they say"to bad" then threaten to sue!

Is the amp ohmage and the sub ohmage matched correctly?

 
Rep Power: 0

it takes a ridiculous amount of current to do things like that to a 10 inch run of 4 gauge.

what amp are you using?

Another thought.. I don't think this would cause that much current but is your gain at the correct position for the voltage of your preouts?

im just goin to take it back to the shop cause i dont know what is wrong and i cant really explain cuase i dont know that much

thats your safest bet, im curious what caused it

me too i messed with the gain a little bit and that seemed to make the ground not heat up anymore but it wasnt really doing any differnece when i was turning it up and down so i dont know if the amp is just had it r what im confused. but o well ill be taken it in here soon when i get free time

The amp still works? What is it?

 
Rep Power: 0

i took it in today and they said taht it was one of two things
1. the ground is not grounding properly so it has to much resistants so they grounded it more
2. they amp was sucking up to much power so it was low voltage goin to the amp and causing it to do that

but who knows it seems to be ok for now

I would say the ground was loose, becuase like luddy said it takes alot power to just melt 4guage!

amp still works yes
and its a crossfire vr602

hmm...if ground was loose, wont there be a lot of sparks, and the constant sparking would cause a lot of heat?

maybe that's why it melted?

Thats why, When I installed for a shop we would send them back to crossfire but in order to get a credit it would have to be blown, we tried to plug them in to 115v wall socket and they would still work, until we plugged the 115v into the speaker output side of the amp. They are pretty well built amps.

NEVER threaten to sue, EVER, if you do 9/10 time they will say, "At this time I will have to end out conversation" you SCREW yourself over by threatening that, especially if u don't 100% intend to. Always ask to talk to a manager, go higher till u get what you want.
