Do you have a nulti meter?? If so set it to DC voltage and unplug the rca's from the amp and also disconnect the speaker wires to the amp..
Power the amp up with only Power ground and remote hooked up to it. Place your black meter prob on the negative speaker terminal on the amp and the red probe on the positive speaker terminal of the amp.. What is the reading you get when you do this??

What's your net impedance? And you say "the gain is down" but what does that mean? How did you set it? ------------- Support the12volt.com

I set the gain by turning my volume up by 70% turned gain up till distortion then turned it down on my deck in my car there is a thing call hpf lowest is 50 and the highest is at 125. What should it be set at

OK, well at least you set it using a method that actually employed a signal. :) This guide might help you. HPF means "high pass filter" and it is for mains, NOT subs. If it is part of your subwoofer circuit, TURN IT OFF. This is likely your problem. The subwoofers should be crossed over using something called LPF or low-pass filter. Set it to about 100Hz. ------------- Support the12volt.com

Personal preference, but it MUST be set on LPF or lo or low-pass, or something like that...
The exact frequency will be up to your personal tastes.

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

Your subwoofer should be connected to the subwoofer output on your head unit, then see page 57 of your owner's manual for instructions on how to turn it on and how to set the low pass filter. ------------- Support the12volt.com
