problems with sub

[Marc]

now then, i got a jbl 10" sub runnin of a JBL (360 max power) amp, but my mates runnin a splx 350 amp with a CT 10" sub n his system seems to be louder n his sub moves a lot more.
does any 1 now y this is cause im lost?

[epo]

maybe he has the gain turned right up :?: :idea:

bridge yours and turn the gain and bass up, it will move. it it dosn't take it out and have a look for any small tears in the voice coils. if there are any tear's then its had it. time for new 1.
