My sound system consists of jaycar competion 4 channel amplifier and 6" splits and pioneer 6X9's 12"sub and head unit, it is so loud, It look messy but seeing it up close it looks different. i custom built a passel shelf that is fixed too the car so it doesnt rattle and is more solid too hold my 6X9's . The whole system cost about $1000 and has more than enough power for my liking. On the passel shelf i brought a pioneer badge which makes it look heaps better.
