ok so got a bit of an issue here.. got a 91 240sx coupe with active speakers in it. prior to me the guy had some pos deck that i wanted to get rid of. so i went out and bought a alpine 9886 deck for about 350 bucks... so wire it all up.. correctly... only to discover it makes NO sound whatsoever! powers up just fine, gives signal out to the amp for the subs just fine, hell everything works except no power to the speakers. the deck puts out about 18 rms watts to each speaker. what im wondering is could the factory amps in my car be whats causing the issue. the deck was sent out and worked just fine at the shop. all the fuses in my car are intact and working, all the wires are correct. deck has everything wired up and gets power and everything... WTF!!! need some ideas here!
