Hey I was wondering what good cheaper amps (around 300) would run two SSD 10s with copper coils. I have two in the mail right. Do I need to give each 800 watts to be decently loud? Also wondering if will likely need to do any changes to my electrical system. I've tried to see what amperage my alternator puts out but cant find info, so if you know what an '06 Rav4 without tow package does that would help a lot. Otherwise I think I'm gonna call the dealer. Thanks for any help!
