[mickskillz 10+ year member]

I have a jl 300/4 in my vehicle.... it's currently running off my stock headunit with a 4 channel line output converter... i have the front two channels running in stereo pushing a set of diamond audio hex series s600's and the rear two channels bridged pushing a rockford fosgate p3 10 inch sub(dual 2ohm coil wired in series) i have the front channel rca's coming from the loc connected directly to the front channel on the amp and the rear set connected the same way to the rear channel... the amp's is in 4 channel mode and the input switch is set to high input..... i have no bass coming through my sub at all... it doesn't make the sub bump barely at all... is there some special way to run this amp with the front 2 channels in stereo and the rear 2 in bridged mode... please help... tried adjusting the gains and no luck... do you think this amp is enough power to push that one sub.. or should i look into a 500/1 please respond... thank you

Try switching the input voltage to Low on the rear/sub channel which will actually give you more output all things equal. Just wire the amp using the bridged output for the rear channel, just like it shows on the amp, it has the - and + for bridged. Make sure you have the filter for the subs set on the low pass and the freq range on the rear to X's 1 and not the X's 10. Do this and let me know
