could an amps internal HPF be bad??

I am getting terrible output from my system, and I know its not my subs and Im pretty sure it has nothing to do with my box.

I just got a refurb opti2000d and im getting NO low bass at all and huge peaks when songs play. Im thinking its something with the amp???

Try running it without the filter to find out. Mess with it. Wire it to a higher impedance, turn knobs etc. It may be the amp but make **** sure before you send it back that it is a faulty amp.

im runnign the setup in my sig..

there is no on/off for the sub sonic, its set at the lowest it goes, 15hz.

The LPF is at about 100hz. I got the subs wired to .67 ohms.

How would the ohm load affect the requency response??

double check tthe + and - of your subs. I had a very similar issue to your description and when I switched one sub's + and - around it start sounding normal... they cancel eachother out or somethin...

An Opti2000D has a regular HPF? (not talking about the SSF which technically is a HPF ....)

And if so....why is it engaged while running subs?

anything on an amp can be bad... check that you wired everything right, and if you are sure the amp can be the only problem, send it back.
