Newbie help needed - amp/sub

[Chippa02]

Got it. Then the original 250wx4 Ohms still stands. Will you be using the front bridged channel or the rear?

Ch "A" on amp I believe is the fronts...B ch rears...I have bridged sub to B channels and plugged RCA from LOC into B channel....ive also tried A channel on RCA on amp....maybe i could try bridging sub on front channels??

Plug both Front RCAs. Would you post a picture of the amp endcap that has the x-overs? I want to see if it has RCA summing.

That's what you have to do.

You can use the front channels for the front or rear speakers.

You may have to turn up the bass in the radio eq to get better output.

Found the problem.....speaker tapped into was out of phase...swapped +/- around on right side and tuned it all....working great....being out of phase on LH -RH was cancelling each other out
