Your going to need an amp, the Alpine 7903 is a preamp only unit...

Well i never found the need to own any amp but i do happen to have two mint old school? Alpine 5301? that i found which was in one of my 89 crx that i sold. So will 1 or these work? Just match the wires i take it? Would be the first hooking up with amp..lmk

 

Alpine 5301? never heard of it, are you sure the model number is correct?

However any amp with RCA inputs can be connected to that HU. 94

 

My mistake model is Alpine 3501...its some old school amp found in old of my crx that I sold (89?)...will those work? How would I go about it to get the 7903 working??

 

OK, good little 2x13W RMS amp, [Made In Japan].

Connect the power and ground for the amp connect speaker outputs from the amp to the speakers, gray set is for the right speaker and white set is for the left speaker, the black tracer is the neg.(-) connect the amps control lead to the HUs blue/white lead, plug either the front or rear output RCAs from the HU to the amps input RCAs, your done. 94
