i just got my car about a month ago, and ive saved up some money to put in a system. im looking to replace my head unit, replace the stock components (6.5's) and replace my 10x4's in the back of my cab with 5.5's, and custom cut a plate to install them into the spot of the 10x4's...im not sure whether i want 2 10' subs or one 12". and im also debating on whether to use 2 amps, one to drive my mids and highs, and the other for the subs....or just use one 5 channel sub. ive heard soooo many differences in opinion when it comes to brand. what im looking for is a clear and crisp sounding system (not bass-heavy) Any suggestions would be highly appreciated.
