JL Audio Amp Help

[recklessspyder]

Hello all,

I bought a setup from a fellow user and need a few pointers complete my setup with a JL 1200a amp and stealthbox sub.

I followed BSW PDF/Video on their install and have the 1200a instructions as well along with the previous users cables (and extras).

I wired the whole thing to completion and found that when I have the RCA's plugged into the amp (L and R) the sub output is diminished....when I only have one plugged in (either one) it sounds so much better.

BSW's PDF says that I might have a + - switched up but I rechecked and think I'm good.

The only issue that I can thin of would be the cables. I have spliced RCA cables which I don't think he used....instead he made his own RCA with speaker wire. Again, I don't think the positive/negatives are messed up as I checked his custom connections as well.

Oh...I've spliced for connections at the connection at the amp (non-dsp)

Let me know what you guys think

Thanks
