ALPINE mrp-m1000 Gain Setting Problem

Ok I tried puting the sub level at 15, and with the volume 80 % up and the gain at max i can still only get 600watss out of it 42V at 3 Ohms. Now if I turn the LPF up from the lowest 50HZ to say 80HZ the Voltage jumps up to the 60's.

I change out the RCA's and still not getting any more voltage

turn off the LPF & set em in full range

The LPF on the amp can only be turned down to 50hz, but all the filters on the deck are off.

Set what to low range? The amp is a mono amp. Thanks.

not down...up. let the amp have as much of a frequency range as possible

Ok thanks. Setting the gain with the LPF turned up..You only have to turn the gain up maybe 1/16 of a turn to get the required voltage.

is it still getting too hot? not sure about that. and when you set the lpf at 50 and use a 60hz tone you are blocking a part of that 60hz tone limiting the amps output if that helps clear that up
