milesmiles Posted April 17, 2009 Report Share Posted April 17, 2009 What do you mean pulsing in and out? Do you mean not moving a lot, or moving fully but just very slowly? Quote Link to comment Share on other sites More sharing options...
troy Posted April 17, 2009 Author Report Share Posted April 17, 2009 they go to full excursion out then back in. it does it pretty slow.

thehoe92 Posted April 17, 2009 Report Share Posted April 17, 2009 the only thing I can think of is polarity. the technique is used for speakers when you don't know which is + and which is - Quote Wouldnt be thehoe92 without teh purple Link to comment Share on other sites More sharing options...
troy Posted April 17, 2009 Author Report Share Posted April 17, 2009 i know positive form negitive. the wiring is right. its in the signal going to the amp. rcas are not the problem ive switched like 2 pairs Quote retarded build on the way..... 2000 bagged s10 2 hdc3 15s aq2200 aq4x90 stinger/knu wire optima batteries 220 amp alt fosgate hu/mids and highs Link to comment Share on other sites More sharing options...

I'm thinking of everything ATM man. Quote Wouldnt be thehoe92 without teh purple Link to comment Share on other sites More sharing options...
audiofanaticz Posted April 17, 2009 Report Share Posted April 17, 2009 i know positive form negitive. the wiring is right. its in the signal going to the amp. rcas are not the problem ive switched like 2 pairs Did you try a different rca output off the headunit like a front or rear? Just to test that its not the sub output channel. Also is your subwoofer volume turned up on the headunit? did the rca jacks in the amp come unsoldered or break the joints on the board? Does the amp work fine in another enviorment(different vehicle, or bench testings)? Quote Link to comment Share on other sites More sharing options...

Does the amp work fine in another enviorment(different vehicle, or bench testings)? it only has one output i dont have a sub volume thouhg. no the jack never came unsoldered and yes the amp works in another car. thats why i think its a signal problem.
