Just got some Pioneer TS-A6874R 6"x8" 3-Way speakers, and a Kenwood Kac-8105D 1000-Watt Class D Mono Amp for my soon to be here Kenwood Kfc-w3013ps 12" 4 Ohm Sub... as you can tell I'm on a budget but really want to upgrade my head unit, still using stock head unit! Any suggestions out there for a good, reliable unit. If possible i plan to run the door speakers without an amp, ill just lose sound quality right? I just want the unit to be able to be compatible with my iPod! Thanks in advance!
