i think it looks really **** good.
but carpet (or paint) is a must, and those speaker wires DO have to go. maybe new amps tbh.
what kinda subs are those? and how many watts a piece? i think the battery looks cool there. its is kinda cramped between the subs tho. are the subs sealed in the front? why rear firing?
maybe put the outside amps on slants like this \____/ i think that would look great.
you can drill holes in the wood, and feed the wires under the board, and up thru the wood to the terminals to hide the wires. i think it would make it ALOT better looking.
