New here fellas and just got back into car audio after a small hiatus. I have a dilemma and not sure on what direction I should go. 2004 Tahoe, mechman alt, all the wiring, batteries and support system for a good system(in my eyes anyway). I am currently running a DD Audio M3 amp on two Skar EVL 18's but I am in the process of going to a wall and adding two more 18's. What I'd like to do but cannot afford it is just add another M3, but can't do that !! I am leaning towards one of the Brazilians in the 13500-15000 watt range and keep my gains fairly low. If there is a better option out there I'd love to know about it guys.
