i am putting together a new system for a 2001 mazda 626 and would like advice on an amp to complete it. Right now i'm going with a pioneer premier 760 head unit and the JL 6.5" XR componenets in front and xr coaxials in rear. I would like to get the JL 300/4 to complete it but I would rather pay closer to $300. Any suggestions on brands and models as well as links would be greatly appreciated?!
