the HU is the very first thing in the order of things in the audio system. if it sends crap on to the amps, they will reproduce crap and send it to the speakers, and you will hear crap.
i noticed a huge difference when i switched from the Panasonic CQ-VD7001U to the Alpine CDA-7998. it sounds so much better!! but the screen is messed up in the alpine and i'm trying to get with the seller to resolve the issue. so i don't know where the EQ's and Levels are and can't change them since i can't see them, lol, but if it sounds this good now, i can't wait to get a new unit and do some tuneing!!
Well i still have the Factory stereo to a 03 focus and using that with my PA amp & sub there is good spl but not much sq do u think if i change my HU i will give my subs better sq??
Right now i have my amp wired to my HU with a Line Out Converter(i think thats wut its called) is that a possibility why my system doesnt got much sq? Did i hook it up wrong?
