Looking to install aftermarket subs

[1791]

set it up how you like it to sound. i do suggest you keep the subs at 80htz and set the head unit flat on bass or negative if you don't have a amp on them, if you do i normally do 100 or 110 on the highs with 12 db crossover slopes your not missing anything, the spikes are 500 rms = 1000 for the set you do have box rise but watch the clipping. for the air space in the box you really only had 2 choices the spikes and sundowns i have tried a few sets and the spikes worked out the best for sq jlw3's would be next but they are too much $$$$$ jl is proud of those.
i have a dsp so changing the slope, levels and cross points is on my app and done in a instant and from the drivers set
