This is my first thread here, so hi all! over the last week i did my own sub, head unit, and amp installation (i have knowledge in the automotive field and knew what i was doing) and installed 2 12" MTX Terminator subs in a prebuilt enclosure and paired it with a boss R1100M amp and pioneer head unit (i knew that the amp didnt put out anywhere near 1100w) but figured it would sound alright for my first system. i drive a large car (2000 crown victoria LX) and figured that it might just be slightly quieter. after working with both my amp and head unit's settings i reached a point where i had a decent amount of bass. Fast forward to this week and i helped a friend install 2 12" Kenwoods, which came out to be a lot louder than mine. To test if it was just my system, we wired his amp and subs into my car and it turned out to be much better. I decided to ditch the MTX subs and my amp and go with 2 Kenwood 12's (3013ps) and an Autotek amp, but i was wondering if the box that came with the MTX subs would be adequate for the Kenwoods, so if anyone has any knowledge as to what would work, it would be greatly appreciated.
