Im kinda new to all this. Im gettin a new CD player for my truck cause the stock ones broke. Im thinkin about gettin some subs. Maybe Sony Xplod 10's. Do u have to have an amp to run these? I think u do but not sure. If u do then I would prabaly go with a Xplod amp. Is this a decent setup for it to beat pretty good? Will I need different speakers?
