Now that we can totally agree on.. Like I've said before, Just a new HU and broke out F-R channels at the amp, and running an amplified subwoofer off the HU's RCA sub out has made a world of difference.. even my teens say "Dad's jamming out".. LOL

It all comes down to how much you have to have out of it.. how much you want to spend.. $120 Clarion factory refurb HU and a $150 300watt 10" subwoofer amplified cannon got me to totally acceptable. (bass cannon was free..just run with old folks that buy a used car..they hate that stuff! LOL)
