Sensing it is good.. You want to eliminate the clipping..
However, the 420 may help by acting like a line driver. I know my new Alpine HU only has 2V pre-outs. One of the main reasons I am getting the 420 is to bump that to 5V. Cleaner signal that the amp has to work less on to boost. Less amplification allows for less power use /less heat and less multiplication factor in boosting a slightly dirty signal.
He needs to work on retuning the system with or without a 420. I think the problem people are running into is these systems are getting so darn loud it's getting more and more difficult to tune by ear which was hard to to do properly to begin with.
