Summary: I had for years now.. Got 4 years ago two in ported box in back of 79 Bronco. I had the two 2 ohms rated at 400 watts rms 4-channel amp. It used to set off car alarms 50 ft. away at Kaiser hospitals and parking garages at Well's Fargo Banks.
Summary: When Amazon asked me to rate this purchase I was a little puzzeled? This was my first ever Amazon purchase and it was over 5 years ago! Well, if you're still selling it, I'll give it a great review! I love this sub!
Summary: I replaced my aging 10" Fosgate sub with 2 of these, and the sound is that much better. After figuring out the wiring for dual voice coil (the manual gives you about 20 different configurations) and doing some tweaking, these sound fantastic!
