how to 'tune' an amp?

[96toyot100]

i took my amp out of my truck to try to sell it, but nobody wants it and i made the mistake of not putting it back in my truck...my little cousins got ahold of it and started playing with the switches and adjustments...now it doesnt even power my subs. there are 2 subs, 1100 watt each on different channels.....how would i tune my amp to get them to work?

look over all the obvious settings and make sure they are where they should be. check that the gain isnt turned all the way down. and make sure the crossover is on "Lowpass" if the amp has one. check your fuses and then hook it back up. you should get something outa it after this, if you still have nothing, then it sounds like they did more than just play with the knobs.

or, maybe theres some apple juice or raisins inside

You cant tune an amp, but you can set you gains and turn on/off your crossover.
