alright my friend has a system problem. hes got 2 12 inch solobarics l7's and a hifonics amp titan class d mono block tx1505d. and there hooked up 1 ohm load.

whats going on is when he turns his pioneer head unit up to around 30- the subs just start thumping - not to the beat of the music or anything- and when he pauses the cd it still continues to do it.

does anyone have any clue as to what the problem might be?



JBO'S Mr. 64.....

Check and make sure he has a good ground, and check the RCA's.

yah probably rca's connection or the actual input piece in the amp. mite have gotten to much pressure put on them and busted the soldering

a friend of mine's stereo did that as well when his gains were turned up too high, hes got a little 14ga ground wire about 3 feet away from the amps, and a 4 gauge wire spliced to 14 ga to run the two amps. Never thought it would be the ground, but I did tell him to go buy an amp wiring kit because his wires are probably too small.

i had the same problem once and my rca's turned out to be bad, theres a way you can test them but i dont remember how, im sure somebody on here knows





suckin ain't fuqin, and eatin ain't cheatin'

what is happening is the subs are going into a thermal mode and motorboating. like everyone said check your ground, make sure the paint is scrapped off, and check your rca's. if all that is cool go to a local shop and have them bench test your amp because your amp might be bad.

Check the gains, subs could be clipping, amp could be clipping.
