That's good your amp isn't faulty. Now go back to that installer and explain your problem to them :)

aha, so it was a short.. it was just at the LOC and not at the amp.
my prior post was closer to the problem.. it was just a matter of finding where the problem was.
I was thinking it was at the input stage, and it was at the line out converter

glad ya found it

Well actualy I figured out the problem. When my step down was put in it was put in incorrectly. Where the wires should of been + - they were hooked up - +. Ie causing them to be inverted when both rca jacks were inserted. My amp is not damaged.

dont install a damaged amp.....if your amp is ok you shouldnt ahve this problem

wait... so putting both RCA's into your amp for the l/r speakers causes them to short?!

How can i avoid stuff like this when isntalling my amp?

the amplifier is damaged.
you have a bad ground line for the line in signal inside the amplifier causing a short between the two channels.. one or the other works alone, but connecting both at once causes a short between both channels, and thus your problem.
this also explains that thumping or pulsing noise in the other thread.
time for a better amplifier

I have a two chanel class d amp. I have it hooked up to 2 subs, on two chanels. They are not bridged. The amp has two RCA input jacks. When I put one in both chanels play. But when I put both in they dont. My RCA conections are good because they play when either the L or R connection is in, but just not both. Can any one help me out. By the way the RCA connections are from a step down.
