I have a radio, a JL 300/2 amp, and 2 Sony xploid subwoofers 12 inch with the box that need to be installed but I have no cables . I'm wondering how much should I be charged to install all 3 things ? Also is that amp a good amp? And what about the speakers ? Are they good also?

 

the amp is decent but the subs are well umm junk. why not try and do everything yourself if you get the harness for the radio then it won't be difficult at all. price i couldn't tell you i do my own work.
