Rick Ning Unregistered guest | I bought one because I heard nothing but good things, I have it hooked up to an MA Audio HK 1997 1200 watt mono block (not the best I know) and every time I turn the bass boose above half the sub screws up and constantly vibrates. At half way it bumps, but not very hard at all. I have 4 GA wiring and was wondering what I can do to fix the problem or improve my system? |

Gains usually shouldn't be more than half way up. Don't engage bass boost, it screws with the gain setting of the amp. Also, what kind of box do you have the sub in? If it's aprefabricated, cheap box (Like Q-Logic, RT enterprises, etc.) then it will have air leaks, and the lack of bracing will definately degrade the SQ of the sub. There is no cheap prefab Best Buy/Circuit City box that can withstand the pressure of what a 12W7 can put out, you need a strongly made box. |

Rick N Unregistered guest | I have it in the JL made prowedge, its a nice box but I should probably get a new amplifier? |

pot smoker Unregistered guest | get the 1000/1 from jl. it will power the 12w7 perfectly fine. although, you will definetly need to upgrade your alternator because the 1000/1 is supposed to be fused at 100 amps. |
