Hey guys, i was thinkin about getting a new sub. Currently ive got a rockford HE2 400w RMS sub in a sealed box coupled up with a MTX Thunder 421D amp rated at 420 W RMS @ 2 ohms. If i were to get an RE SE 12" and put it in a properly built ported box, would it pound hard enough to feel in my chest and keep better quality than my current sub on the same amp? The rockford ive got now hits hard enough for me to feel, but id like a little more. Thanks.
