OP if you are intested in Skar I have one FS with a box that is under your budget by a bit... assuming we are talking about subsdc, ascendant ,skar,sundown
You do realise youll need a box, wiring, electrical upgrades if needed, a deck, dash kit and wiring for that.... Many things that your not gunna get for under 300 lol300 total? i cant spend too much
