I have a kenwood 9103d running 2x rockford fosgate p3 but doesn't seem to be thumping the subs hard enough ? amp too weak ?

what rms are the subs and amps??

I think subs are 400 rms each
and
amp 900 rms x 1
500 rms x 2

hmm should be fine to run the two subs....just check that all the wiring is good and that the bass levels on your head unit haven't been turned down...

might be worth going to alberts and getting it tuned should cost about $20 or so..

are you sure? normally the value for a 2 channel in bridge configuration is more than the two doubled...
