Make sure your safety mode is off. Go to mode 9 and ENT and make sure it is off. If it still dont work you proabably have bad RCA wre or speaker wire. Hope this helps!

Powers up no sound out


Hello jreinhard623,

Check the speakers and wiring by substituting a known good speaker and check the amp inputs and RCA cables. Also make sure that the input gain and other controls are set properly. If there's still no sound, the amp itself is probably defective.

I need a manual for my amp any ideas on how i can get moore base out of my alpine?


More power. get a 0 gauge power wire that will help. also try a gel cell battery as opposed to a liquid one. other than that if you really want more punch try buying a bigger amp. Or maybe the issue is not your amp at all it could be the subs you are running and the type of box. Not all boxes are intended for all applications.

Lights on, nobody home


Appears to be an issue with current. Is the speaker the correct impedance for the amplifier ? Have you confirmed there are no short circuits in the wiring ? I'm not familiar with this particular product,

The alpine catalogue gives recommended amp/speaker combos. If you don't have an aplpine sub, then look at the specs and find a similar one. You may be trying to load the amp too heavily and it will protect itself.
