[QUOTE="kebas239, post: 7635006, member: 638452"] Hi guys! I recently purchased an Alpine SWR-1223D Subwoofer and an Alpine MRX-M50 Monoblock amplifier. The Sub-woofer is dual coil at 2 ohms and the amp is rated for 300W at 4 ohms, 500W at 2 ohms and 300W at 1 ohm. I realize I should have bought the dual coil 4 ohm sub-woofer to create a 2 ohm load but that time has passed, so I'm asking this assuming I'm stuck with the sub-woofer I have and that I cannot replace it. My questions are: 1) What is the ideal setup for this sub and amp? According to the spec sheet, I get the same power output at 4 ohms and 1 ohms, so is there any compelling reason to make my amp produce more heat and higher distortion for no difference in output? 2) Why would I get a LOWER power output at 1 ohm?
