your whole thread makes no sense,but wasted b/s when you could look up other threads posted in tech to answer your questions,and why put a low grade 5x7 that has no sound,and the amprage equivalent to a clock radio,unless for door speakers for low mid range sound like stx's had to mimic surround sound which was a ford joke.5x7's have no base all treble,everything i have was professionally installed replaceing the old factory ragged stuff same size except the front dash 4 inchers original was like 3 1/2 a small moded plate alowed the 4's, thats keepin it simple to original speakers,so look up tech threads or take what advice ya get n live with it with some respect.and i posted you can read my signature for right explanation of original sizes if you had respect to read my sig profile you would have your answer n peice of mind, what a joker thread lolz.¿
