okay, the title is slightly off
but here it goes:
I have a JVC KD-G645 unit with 2x pioneer TS 6975 speakers, an alpine woofer (complete unit with built-in amp), currently running in car.
I have a 4-channel crunch amp which I'm about to fit in my car for the speakers, the remaining two channels will not be used. I know the wiring and fitting part, but don't know the tuning part - I was working on the car and it started to rain, so while I am waiting, I'm writing here for some help on amp tuning.
the alpine 10-inch subwoofer unit amp has three adjustments:
1 - crossover freq: 50 - 150
2 - level: min - max
3 - phase: 0 - 180
the crunch amp has alot of adjustments possible and whenever I see them my mind blows:
input level, HP adjust, LP adjust, bass adjust, treble adjust, a selector switch HP-LP-FLAT, another selector switch for BASS/TREBLE on/OFF
need help with both amps
how would I go on about adjusting / tuning them
thanks
