I've got a jbp bp300.1 connected to a mtx 8000 10" dvc wired to 2 ohm. Also installed is an alpine 3548 which drive my mids with 80 W rms per channel (2 speakers in parrallel, 40 W per speaker). The problem is that my sub is really really quiet. With the alpine's sensitivity turned down to min and the jbl's turned to max, with full bass boost, the bass is only barely loud enough to match the volume of the mids. I used to power the sub with a phoenix gold 2 channel amp that gave it 175 rms, and it's sensitivity had to be turned up fairly high as well, but not all the way and it didn't need any bass boost.
Any ideas why the jbl is so quiet?
Thanks
what kind of deck are you using, does it have a dedicated sub output, and also what kind of rca wires are you using?
-------------
Connect only one voice coil on the sub and have a listen, then try the other one and have a listen. You may have a bad voice coil or a out of phase problem.

Top Secret, I can tell you but then my wife will kill me.
if you have the amp's daisy chained...the output on the alpine running the other amp, the gain on the alpine may control the output as well, be more in detail about how they are wired

i have both an alpine + jbl 600.1 turn the sub output up... on mine u have to push in the volume knob and turn it to like +15 and see wut it does if im not mistaken it is the output level of the subwoofer line at least on mine it is
I have a jvc sx980 deck... one pair forward, one pair rear outputs. I have a lowish quality rca cable from one pair of the outputs into the trunk, where each channel is split with a y-cable and one line goes to the alpine, one to the jbl.
I'll check the voice coils.
