This sub hits hard!! however after hooking it up i noticed it does not play every note. cannot hit the highs well and the low lows. overall it bumps!!!

Review written by Kevin W from Red hook, NY

I own 1 of these and hooked it up to my jbl amp which is 1000 watts rms at 2 ohms. this is exceptional because the type x sub is also 1000 watts rms at 2 ohms. I have it in my 2005 mustang gt and i feel like either my brain will melt or my throat will vibrate to pieces. this sub is so clear and so hard hitting it is ridiculous. the low bass is so deep it is unbelievable. i have it in a 2 cubic foot box and it is at 155 db don't believe me well buy one and prove me wrong. this 1 12 inch sub hits harder and is louder then my previous 2 15 inch subs combine. my grandfather was in his house 1/4 mile away with the air conditioner on and a radio playing and still he could feel and hear the 12 inch type x subwoofer bumping the country. yes i said country music. when i play hip hop music such as the song "a millie" well forget about it i might as well take my trunk and rip it off lol. will my warranty for the sub cover my trunk haha. I definitely give this sub a perfect score. BUY THIS SUB ASAP AND BE AMAZED.

Ok so about a month ago my 04 12inch kicker L7 voice coil fried. So I decided it was time for a new a sub. I wanted something with better musicality. While the kicker was loud it was sloppy. muffled, and muddy sounding all the time and the bass was always loud and you couldn't differentiate the tonal qualities the bass had to offer.

For my lows amp I have an older KX600.1 it runs about 745 RMS so it has got a little bit of power but not a beast by any means. I wanted to get a sub I felt had better sound quality and product quality. I had several opinions, Kicker comp series, Rockford T1's(second choice BTW) Jl Audio W6 and W7. I was really thinking the W6 was perfect for my amp until I on a whim decided after reading reviews and watching Youtube videos that for a single sub I was going Alpine.

I immediately was scared since I hadn't heard them before I had only heard type R's and they sound great best sub for the dollar IMHO.
Well I got a vented or slotted box and now have the Alpine hooked up and the sound quality difference is night and day. The Kicker was all over the place when it came to power it never really got louder when I turned up the amp while the Alpine continues to get louder. The sound difference was my biggest sticking point or SPL, but little did I know that this Sub would get louder and much much deeper with better response. I have tested this sub with Godsmack, NIN, Black eyed Peas, The roots, Nappy roots, Bedouin Soundclash, Breaking Benjamin. All of these genres sound better, even Rap or R&B which is suppose to be Kickers MO. I think the only sub I liked better for loud good bass was the W7 but honestly the sound quality wasn't better which it is suppose to with a $839 MSRP sub compared to $450. I will say the W6 and the T1 were the only comparable subs, the W6 didn't get the volume I wanted the T1 did but was a hair worse in sound quality. The honest to god truth for non comp( sorry I mean serious comp like SPL comps) subs I thought the T1 was the best until I heard this now I couldn't be happier.

If you want two subs go with type R's or Type X's if you have a little more coin. They both are built for quality and great price to boot. I don't test DB's or anything like that I tested my ears and the bass coming out of these is perfect according to my ears. The low extension is amazing and better than the L7 while the volume is very comparable if not better(actually its better for sure). Kick Bass is amazing as well ok I am done sorry to ramble but I love this sub. It sounds absolutely Perfect. GO out and buy one or two you won't be mad you did.

I just bought 2 of these 12" monsters to put in a cut through box in the back of my 02 silverado. I havent heard them in person but i seen some videos and heard the type r's, so i figured.. go big or go home. im gonna be running a 1000 alpine mono amp to each one. hopfully it will sound good.. i never boght a system b4 but i have about a $3,000 dollar list racked up and i dont like to go cheap. haha this is gonna prolly be way overkill for this extended cab truck but i cant wait to hear them

The best of Alpine, what else is there to say. I bought one 12" of these and put it in a custom box, with a 2400watt amp. It pounds my SRT-4 as well as many cars with two 12's. It also sounds very clean and has a large range. I highly recommend this sub for people who want bang for there buck. You wont be disappointed.
