Awesome subwoofer for a decent price with good sound quality
Good punch and sound quality without breaking the bank. It only got better after it broke in. Powered by JL Audio JD500 amp, 600 watts@2 ohms in a 1.7 cu.ft box retuned around 33Hz. Just at RMS power for now. Any of negative reviews that said it blew up right away apparently didn't know that both speakers and subwoofers have a break in period but I digress. The only negative is I should of bought 2 and run a pair for even more thump.

5.0 out of 5 stars Hits Hard, Very High Quality!
Reviewed in the United States on October 1, 2022
Verified Purchase
Alpine makes some of the absolute best speakers on the planet. The Type S and Type R. Simply stand out the most. This subwoofer hits very hard as long as you have it in a box that's not too small and it prefers to be in. An airtight box, not a ported one. I have paired this up with an Alpine 500D Mono amp and it hits so hard. I had to turn the amp down to 60%. Very good quality for the money. Worth every penny.

5.0 out of 5 stars Awesome dual. voice coil sub
Reviewed in the United States on May 22, 2020
Verified Purchase
Ok...it has two 4 ohm coils in it...wire them in parallel and you have a 2 ohm 12" speaker that will take 500-600 W RMS...its a good sub and does a great job...

If you want to run two of these at 2 Ohm, you need the "D2" version 12" sub, which has two 2 Ohm coils in it...wire it in parallel and then wire the other speaker to it in parallel...so you get {1/2+1/2} = 1ohm, and 1 ohm +1 ohm =2 ohm for the pair.
