[QUOTE="t1n0m3n, post: 5378369, member: 553573"] How many watts RMS @ 4 ohms is your amp? My rule of thumb for awesomeness is 75% to 100% of the sub's RMS for the amp @ 4 ohms. You can get away with less if you drive the amp really hard, but then you have to contend with amp clipping, overheating, and sloppy bass. If your 4 ohm RMS is truely 550 watts, then you are at 55%. So the 4 ohm spec of the amp you should be looking for should be around 750 to 1000 watts. The Hifonics BXi 2608D seems to fit this bill perfectly. With this method comes the responsibility to tune it correctly. I tune mine by ear, but I am a deaf old man. You should never, ever, ever, ever clip your speakers. Realize that any material between your ears and the speaker cone can muffle the sound of the speaker clipping. Do this correctly and you should have a system that lasts forever, never has thermal shutdown, and sounds awesome. Do it incorrectly and you will smoke your speakers. This might sound crazy, but do yourself a favor, once you get a properly powered amp, try running your subs all in series instead of that series/parallel you are running now. I know it will be 8 ohms, but just listen to the difference. After that wire it however you want. BTW, I run mine at 6 ohms and it makes my vision blurry while driving down the road. I am running a 750 watt amp. [/QUOTE]
