SPL??

I emailed them 3 days ago and still haven't recieved an answer.

I have been running all my daily drivers using oldschool mmats .5 ohm stable amps for 10+ years using MMATS with .5 ohm loads in all of my vehicles and have never ruined a subwoofer or amplifier. The old school MMATS amps don't have a fan cause the whole amplifier is a heatsink. The old school mmats amps are an installers dream cause they are so small. If you can pick up a old school. 5 ohm MMATS amp I highly recommend it! The old school MMATS amps have less then 1% total hermonic distortion plus noise even at 1/2 Ohm! They run extremely cool and are proven to be one of the most reliable amps ever made.

Ok, thank you. Do you know what the correct FI recone kit is for the FI BTL UFO Motor? They have quite a few diffrent BTL recone kits and I'm not sure what one is the correct one. None of them say UFO motor.
