Conclusion: My alpine is a beast. It's a jaw dropper when people look in the back of my 2000 ford ranger. Ive given it all ive got and havent been able to do anything damaging to it yet. I ran a 2200w SPL amp and fried the amp pounding it a little too hard. Got another amp on the way and the beast will roar again. I highly recomend this sub.
Conclusion: I bought this thinking it would be awesome, and it was. I had it in a sealed enclosure and it would kick super hard. It sounded amazing. However, just today, it broke just like my buddies type r-12 did. I was in the car listening to music and then the bass stopped. I checked my amp and the amp was fine, but upon inspecting the subwoofer, I found that the spider had broken off and could no longer move.
Conclusion: Well I got two of these bad boys in a custom built to specs candy apple red box hooked to a 1500.1 crunch power zone amp and when I ride though parking lots I set off car alarms and people cover their ears. Even the cart boy said he hears me across the parking lot.
Conclusion: Clean hard hitting lows, need at least 500 watts rms from a good amp to fully appreciate how awsome they are. I like jl audio but i love my alpine type R by far the best sub Ive ever owned. Thanks Alpine.
Conclusion: This sub is freaking insane!!! Let me tell you its so loud its unbelievable. I first had a jeep wrangler and i built a 3ft cubic box tuned to 33hz for it, it was hooked up to a kicker zx 750.1 and it was so loud my hard top bolts rattled out and almost came off driving down the highway. I then bought a audioque 1200d put the sub in a 4 cubic foot box tunned to 31hz and put it in a Volkswagen jetta and it still rattles everything and everyones cars from 50 feet away.
