hey im just wondering if anyone has tried replacing the stock 2011 sony amp with something different? i have the sony system and its good and clear up to a volume and then one notch louder everything distorts. So thinking about maybe replacing the 4 door speakers and probably keep the stock tweeters. And was thinking about just simply replacing the stock amp and mount a 5 channel amp in the same spot. which should give the sub a much better range and power all the door speakers as well?idk, i think i used to be pretty good at this stuff but thats only if i completely overhaul the whole thing.
