I've had it for 8 months, I'm using it with a Trf SMD1000.1 D amplifier, and it rattles the whole car. It easily covers 4 eight-inch speakers and 2 horns; it's worth the money. I've given it so much power that if it were anything else, it would have blown up

I have this particular speaker for a year and I am very satisfied. It gives me the bass I want and it covers 8 speakers and 6 horns. I play it with a trf 800.1 rms and it is perfect. I highly recommend it.
