Does audiopipe make good subs?

Make bass come from subs not speakers?

• I took my car to get wired at audio specialists and the hooked everything up wire, subs, amp, head. I could turn my bass on my head all the way up and it never messed with my door speakers on through my subs. Couple months later i was going to sell my car so took out my subs amp and head only wires i had to cut from the head was the remote wire and ground. A little bit later i decided to keep the car so i through my subs amp and head back in hooked the remote and ground back up (the whole time the amp sat none of the dials were touched) so now everything is hooked up and i go to turn my bass up and its now coming though my door speakers so its really muffled and i dont no why its now coming the the door speakers. The car is a 2001 chrysler 300m

• Answer:

  Could be you havent set the HPF and the LP filters in HU and/or amp/s.
