The BOOM II leaves a lot to be desired but I want to stay (for now) with a 4 speaker system. Am considering a Sound Digital amp 800.4 or 1200.4 pushing Beyma 6.5 in the fairing and replacing the lid 5x7 with 6x9's. Haven't decided on which 6x9's so recommendations are welcomed. I plan on keeping the stock head unit. I know I will need line leveler(s) and other cabling to accomplish this as well as a bracket for the 6x9's. My taste in music is old school rock n roll, r&b and some new stuff. Any ideas will be much appreciated. Oh my budget is up to 2k.
