try matching your lpf filter on both the hu and the amp at 80hz

did that to no avail

Max the amps LPF. Put the HU LPF on 80. Since that sony headunit is the very low low end of theirs i doubt it's doing 2v in the rcas. You answered it for your self when you tested it in your car.

I'm just getting a line driver then. IDK why that sony would have a 2v preout. Thats so minimal

2v is technically plenty. It just comes down to which model will actaully do 2v. Hell play a test tone and use your DMM and see how much voltage is actually going through it.

ill do that as soon as I get a chance tonight

Ill do that...and what do you mean compare the two HU's

You said your HU operates the amp/sub combo just fine and your brothers HU doesn't.

So check your HU output voltage and compare it to your brothers and look for differences that would explain the low output.
