[K10 STEPSIDE]

I built the custom box behind the seats. The biggest thing is having the depth to fit the subs. I am running to 12in Kenwood shallows. There is a big difference in sound from the shallows in my truck to the full kenwoods 12in in my car, but having the sub 6in from your back bone helps with the feel. Also having the subs so close you need a quality sound and seal. My system goes as follows
1-kenwood head unit, 2- spr60's under the dash, 2- spr60c's behind the seat,1-MRX-F65 4-channel amp, 2-Kenwood 12in shallows,1-hyfonics amp. I want to upgrade to a better sub amp and better speakers under the dash, maybe type-x's.
