Current 6 speaker system: Sony memx head unit (keeping that). Hogtune amp and 2 hogtune speakers in stock locations. Rockford pbr 4ch amp feeding 4 polk DB speakers, two 6.5's cut into fairing facing forks and two 5.25's in bag lids. I will be replacing my current lids with a set of AdvantBlack 6x9 lids. Would like to ditch both current amps and all 6 speakers with something with more power. I am on my second RF amp and its lost 2 channels now, the Hogtune deal is still working. Not into audio competition type stuff, just want the hear it clearly at highway speeds. Also want to keep it affordable! So I am thinking I will still need 2 amps to feed 6 speakers, two 6x9's in the lids, two 6.5's facing forks, and 2 speakers in stock fairing location. What would you suggest to run behind the Sony head unit for amps & speakers that wont break the bank?
