Alpine 9813 help

I have an Alpine 9813 in my car and was wondering what the best settings (EQ and crossover) would be. I like bass and loudness....I primarily listen to rap/hip-hop music. My system is as follows:

 Front and back: JL Audio tr525 CXi

                  rec amp power 10-75 watts, 50w RMS, Freq response- 63Hz-22Hz +- 3db

Subs: 2 JL0 10'' subs

Amp(subs) Kenwood KAC 7295 2channel 600w max

Amp(speakers) Eclipse 36401 4 channel amp at 75w X 4

Also any suggestions on what settings I should place the gain on both amps and the crossover at for the amp for the speakers??

  Thanks alot
