[QUOTE="hari-bhari, post: 7649360, member: 559890"] did your first two amps fry as well? if so, then i would say something is wrong with your subs. how are they wired - in series or in parallel? next, where is your grounding point for the amp? did you find a piece of solid bare metal, sand it down, and ground there? for power, did you wire a fuse in between the battery and amplifier? if you have a DMM you can check that the amp is getting 12-14V from the battery. also make sure your power/ground wires arent reversed on the amp. for settings on the amp, start with the gain all the way down, bass boost all the way down, and low pass filter around 60hz (or somewhere in the middle if it isn't marked). then make sure your speaker outputs arent shorted. this can again be done with a DMM by ensuring there is no continuity between the +/- terminals. try these things and then post back with any findings.
