i say amp the jl stuff u have now. if it sounds bad then get new speakers. your running the 2600 bridged for the sub? thats what i'll be doing for around 500watts rms, with the 4800 running the front mid tweet separates. back doors are powered off hu. the 40x4 from the hu isnt rms power, thats max power. constant power is likely 20ish x 4
