Best Buy Customer Reviews
Superior quality subwoofer
Posted by: Troposphere from: Minnesota on
I purchased this sub the first day it was on sale at Best Buy for %50 off. You really cannot go wrong with this sub it is way better than most of the other subs within its price range. Alpine has some of the best quality components in the car audio world for decent prices. 500W constant at 2 Ohms is more than enough power for one 12" and not only does it have a lot of power but it also reproduces bass accurately and cleanly at high volumes. Words really cannot do it justice. Would definitely recommend buying this sub and pairing it with either a Alpine or Sony Mono class D amplifier 500 watts rms.
Current setup: Pioneer 6x8's, Sony CDX GT565UP, Sony 4 channel amp running the speakers, Alpine MRP M500 running 1
Alpine SWS 12D4 sub (in a ported box) use 4 gauge power wire.

$100 for this ? yes please!
Posted by: Unleashed2012 from: Chicago, IL on
I got this sub along with the alpine MRP-M500, both with box and installation cost me $598 including tax and 4 year warranty for both.
Let me tell you, I used to have 2 12" MTX subs about 8 years ago and nothing since I sold my old car. This sub is my first sub in 8 years, all I have to say it hits harder and deeper and sounds better than my 2 12" MTX from 8 years ago. My gain is on below half, -5 base on headunit setting .. and you can still hear me from a block away one a single 12" ... it hits so hard I cannot believe it. None of my friends can comprehand that a single 12" can hit that hard, deep and clean ...
IM VERY VERY happy!

Power for Quality
Posted by: theironman123 from: Wildwood, MO on
All I can say is, wow. I've gone through several sets of subwoofers and I gotta tell ya, out of all of them, these hit the hardest, and cleanest out of all my sets that I have had. I have had 1 10 inch Type R that I thought would hit the hardest out of anything, and boy was I wrong. These Type S's carry old Type R technology with the HAMR sound quality and for what you buy its definitely worth every penny! I would not go with the new type R's over these. If your looking for quality over quantity (sound quality over bass quantity like me) then the Type S is for you! I have an Alpine MRX-M110 that was attached to 1 10 inch new Type R and now I am putting that amp at 1 ohm stable with 800 watts rms so 400 watts each, which is under-powering them and they still hit hard! This is definitely quality work by Alpine! Thanks Best Buy for the Type S's!

A lot of power, great sound, good quality
Posted by: paintballa95 from: on
I got this the first day it came out. It didn't have any reviews but it was the only powerful enough subwoofer at Best Buy. 500W RMS is a great deal of power for a single 12". The rest of the subwoofers were 400w RMS. I got the ported box and the alpine amplifier with this and I installed it over night. Setup was really easy, sound was superb, and the deep bass is hit very well. It's not even broken in yet, so it hasn't reached its full potential either.
Get a ported box for this sub and use 4 gauge power wire minimum.
My amplifier: Alpine MRP-M500

Nothing but regret that did not purchase first.
Posted by: from: Western,NY on
I am very pleased with this sub all the way around. I had a Polk dvc beat on it 18 months then started to back fire. I read the reviews on this Alpine dvc and talked to a geek and said it will do fine on my alpine 500 mono. He was right it is awesome for my taste in music(Korn,Tool,Disturbed,and so on). I have been beating on it for around a month now. I just changed the wire from 16gauge to 8awg and amp is staying cooler as well as sub. It is stated in manual to use 8awg for these reasons.
I am a long haul driver and listen to my system about 12 hours a day and love it even more with this sub. I will buy again with no hesitation and,outstanding addition to my system.

Added theses speakers to the back of my Jeep. Plenty of great sound even with the top and doors off!

This gps is very detailed. I don't like navigating much at night especially when areas aren't well lit. This gps is very detailed and even in minimum lighting you wouldn't miss an exit because it's very detailed and reminds you a lot. The images are exactly how the highway has them. I've always preferred Garmin over tomtom

Great subs for the price. Got my pair as an open box deal in store and saved 40$ each. They were in perfect shape, no smell or scratchy voice coils so I went ahead and got them. Also bought the Pioneer 1600 watt amplifier (also sold at Best buy) to go with them and they POUND. The pioneer 1600 watt mono amp was a perfect match for these as it can handle 8-1 ohm loads (I have my subs bridged at 1 ohm so they are getting the full amount of power that the amp hands out) I've had this system for over three months now and I am super happy with it. These subs can definitely take a lot of juice thanks to the kevlar and superior construction. I will say if you do pair 2 of these 12s w/ a 1600 watt amp you will need to invest in a better charging system. E.g. upgraded alternator and battery as I am getting dimming lights when the bass hits. But that also goes to show just how hard these subs can hit =)

CLEAN AND CLEAR
Posted by: Rateman from: Paradise, OH on
I love this sub. I only have one in a ported box. I have it hooked up with alpines 500w class D amp. I have it hooked up to a factory head unit. Man this thing sounds excellent! Will it give you a constant back massage? No. But it will deff make your music sound 1,000 times better. No one will believe that you only have 1 12in sub in your trunk. I know when i pop my trunk they all say: thats it? I really think alpine did a great job with this sub. The bass is very clear and deff packs a punch. My amp came with a bass nob for free that i use with really bassy hip hop songs, or when I get close to my house. I highly recommend this sup. You won't need to get 2 unless you want a back message and only if you want people blocks away to hear you coming. Personally i just want my music to sound great.
Oh by the way this sub also has great looks. especially if you add the protective cover, which i had to get elsewhere.

Everything a man could want in a subwoofer.
Posted by: PalOfTheWorld from: on
I had Best Buy install an amp and a Kicker Subwoofer for me, which I had bought from them. However, the original 10" sub didn't quite do it for me. So I exchanged it for this Alpine 12" and believe me, it's got all the "ooomph" I could want in a subwoofer for my car, and then some. I'm perfectly happy with my purchase and would recommend it to anybody, along with the service I received at Best Buy for when they did the installation AND the exchange.
