Hey guys I just got done with the boom boom in the trunk n now im wondering about a couple of things.....I got a jl 4300 amp bridged it to 2 channel for the rear speakers (infinity kappa perfect 6.1) to be powered I used the david navone converters which are so sick i cant even explain it and when i plugged in the amp the subs tuned down in volume.... now i kinda remember this happening when the sub was canceled out and the highs were brought up in the car (stock) but the sub never tunned down...maaaaaybe just a lil bit.....but it still seems odd does this happen because the stock amp is tuned to sensitivity or does it happen becuz of the tuning at the amp?
