i have 3 ppi amps i just installed in my sisters car but i didnt have any instructions for them. is anyone familiar with these? if so what are the freqs for the different combinations of the 2 qbass buttons? these are older amps but i figure they are the same since they still use this bass boost feature. thanks for the help. jason

I used to have this amp in my Solara 5 years ago. The 2 buttons select one of 4 four frequencies. I don't remember what the higher frequencies were but the two lower frequency choices were 32Hz exactly and something like 44Hz. For my install, I set it for the lowest frequency which was the 32Hz but the 44Hz might be some use. (As for the two higher frequency combinations, I don't think they are that useful except maybe for midbass drivers not subs).
