Whats good guys just found this board and decided to join. At any rate, been thinking of upgrading subs to FI but not sure which ones. I currently have 2 RF p2's powered by a RF P500.2 with a cap and am pretty happy with it but i want more. I found FI and have heard nothing but good things. Keep in mind i have a Chevy SIlverado with a sealed box under my rear seats. What FI subs could i use with this box or would u guys recomend another box? Really looking into the BL's but not sure what will fit and such. Any help will be appreciated
