My setup:

Focal 165K front components w/ Xtant 4.4 amp
2 10" Memphis Subs w/ MA 600watt amp
Alpine 7995 deck
Visiontek rear (don't really care about these)

Basically i don't know what to set the crossover and eq settings on the deck to be... Any ideas? I think I got the amps adjusted already but give me all the suggestions!

Oh yeah, what are good songs to test the system with?

 

On the deck there are high pass and low pass, the focals should have crossovers on them for highs, set the deck to 80ish. Play some prodigy or some band and if the bass line is only in the subs, and the speakers are not distorting it will give you a good idea of what you need.

If the focals distort on the low beats move the crossover up to where they don't. Thats the best I can do for not listening to it and doing it for you.

 

If it is a component set, then it has a crossover (that little box) so it is already being cutoff by factory specs. So I would put the amp for a "through" or basically no cut off (high-or-low). As far as the deck, I wouldn't mess with that so dont' enable one. This only applies for a component set of speakers.
Adjust gain to match front and rear.

 

If you have crossovers, you should use them, you don't want the components playing the frequencies that the subs are playing to, cross it at around 80 Hz
