this question is for low and all the other guys that know their stuff. so thanks to the punk that wanted my 10 year old ddx7015 more than me I'm going a different route with my install. I'm going to use my stock HU followed by a jbl ms8. I need to know if the stock head unit has a decent frequency response (ie. no high pass filter) or if I need to get a stock ford deck with the subwoofer plug. Luckily the crooks that got my headunit were too stupid to figure out how to get my sub box or amps out. altho next time its gonna be even harder to get that thing out
