[QUOTE="bbka, post: 2963688, member: 570536"] I have one JL Audio 10w6v2 dual 4ohm voice coil sub (brand new) running off a Rockford Fosgate P3001 mono amp (brand new). I finally finished my sub box, so I hooked the sub amp up and had the gain down, filter off, and everything set to zero on my deck. I was going to tune the gain with my multimeter, but it needed a new battery and it was late, so I just set the gain to a little below half to see how this sub hit. Low pass filter was at 80hz and all the settings on my pioneer deck were still at zero. I started the car and popped in a cd, but I could barely hear the sub at all, I literally had to open my hatch and stick my head down there to make sure it was even working. The amp is getting power and it's not in protect or thermal mode or anything like that. The amp is a mono amp, but it has 2 sets of speaker terminals that are wired in paralell internally (A and B), so for a 2ohm sub you just hook it up to speaker terminal (A) according to the manual, which I did. The sub like I said is wired in 2ohm just like the manaul says, so I am good there. My wiring all seems to be fine and everything works, there is just hardly any bump even when volume is at 80%. I called my car audio buddy and he suggested installing my bass boost to see if that helps or does anything, but I don't even know what I did with it, so that's not an option (everybody here says bass boost isn't needed, so that's why I left it out). I played around with the settings on my deck and turned the bass settings up, it did get a little louder, but I shouldn't have to run my bass settings at +6 to hear it. I still think even with the settings at zero and the volume at 80% it should be hitting somewhat decent. My buddy is bringing his car by today and we are going to swap subs, to see what happens, that should tell us if it's my sub or something with my car real quick. I just thought I would post up and see what you guys thought and if you had any ideas/suggestions of what might be wrong.[IMG]//content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif[/IMG] [/QUOTE]
