Stereo upgrade

[Slimtwitch]

So not sure if this is right place was wondering if anyone has replaced their stock speakers and added amp and subs using JL fix 86 on truck with bose. I did mine and even though the fix always says it's calibrated it seems to lack mid bass

I maybe able to help. I have not messed with this product but I did build the first ever JL cleen sweep in a multi auto car that no one in the world had done before. Super pain in the ass. and after that JL improved the units to simplify them. 

 

what channels in the stock wiring have you used? And what is you crossover settings on the amps. Mid bass is the hardest to reproduce.
