Hey guys i got a question that might be simple i just am worried that it might be a broken amp or sub but anyways this is what i got. I current have a KENWOOD KAC-8104D amp & (2) KENWOOD KFC-W3012 subwoofers, i installed these in my civic using 8 gauge rockford fosgate power and ground wires. I currently am waiting for my box witch will be here on wensday. but since i was installing my new alpine headunit i decided to do the sub wiring while i was at it. the problem is that when i turn a cd, radio, or ipod the subs barely move at all. the amp gain is tuned to 31.6 volts which from what i heard is what they are supposed to be at. my question is that could this be because they arent in a box or is there something wrong...btw i have the subwoofer volume at the headunit on max and +3 bass 0 treble. Thank you very much and i appreciate it.
