Basically my bass is cutting out when i boost my Bass Boost, loudness and SLA features etc on my headunit to get more bass *i dont always have it too base'y* my sub is simply bridged to ch 3&4 which are low channels. i played with the dials on the amp, and when i altered the voltage dial it got considerably better and didnt cut out atall. but i lose some quality and bass etc by changing that dial.
Anyone able to help? :)
oh btw. 8 gauge from bat, and earth *ive never trusted my earth but never had probs before. besides that the cable is short and direct to the nut that my rear lights are earthed to. and the paint is all scrubbed off*
cheers!

OK,
If the bass is cutting out then one of two things happening here, the turn on is not enough for such a big amp. Run your turn on to the ignition wires, also if your not giving it enough voltage you may need a bigger alternator too.
I'd redo the ground find a sold piece of thick metal drill a hole the take a nut, bolt, and grounding star to secure it. Also that big of an amp. I'd try bigger wire, go with 4 guage wire.
The system is clipping, you need to find the source of the "clip" to fix it. Does it stop when the bass hits? If so you may need to use another car battery right next to the amp, generally a good dry cell one will work for it. And this will eliminate the need for a capacitor. As the battery will have ready power when needed by the AMP. Also the battery will have to be hooked into the charging system, so as not to kill it.
Post back!
