Ok I'm decent at car audio stuff but some of this is new so I'm just checking if I'm doing it right. Ok so I'm instaling a legacy 10 band pre amp equalizer, a jensen 400 watt amp, 2 10in pyramid original subs with 200rms peak, and an american legacy 600watt amp. I also have an aftermarket headunit and 4 rocksford fosgate prime 6.5 speakers ( both installed) so I have my line out from my head unit to my equalizer. And I have the jensen hooked into the equalizer and my speakers hooked into the jensen. I have done this by putting a + wire to the front left and right speaker and a - wire to both of them and same for the back two (its a 2 channel amp) is that correct? And I have the american legacy amp also hooked into my equalizer and that's poweing my subs. Is this correct? Any tips or things I should add? Is this a decent setup?
