has anyone put another sub with their stock sub in the trunk? if so how did you do it with out damaging the noise between the stock pioneer sub and the other sub?? Its cus i bought a rockford sub 12 inch and box and amp and im trying to figure how i should instal it so i get a good noise/bass volume instead of distorting 1.

 

sure have man. actually i put a JL 10w3 in the factory box, then hooked it up to a 800 watt amp, but later just put 2 . i think thats a bad idea, just put the rockford in and take the 10" out. it will hit hard.
