Let me start off by saying i got this completely free so i took it. I will be installing two new Alpine SWR-12D4s in a few days. That being said, my door speakers will probably be over powered a bit. (2000 watts RMS for my subs, no Mid/High amp). So i took this free Urban Audio Works 200 Watt 4ch amp, model U-2000M. Its old and cheap and everything i have read about Urban says they are garbage. but would it be worth it to install anyway until i get a better amp? or should i just run my speakers off my Alpine CDE-HD148BT until i get one (18W RMS)?
