Simply WOW

The following review is for R-W12D2, which is a part of the bundle you are viewing.

If you want real ground shaking, hard hitting power then look no further. This is all you need. I would highly recommend this sub if you want clear loud sound. I currently have 2 12s and you can hear me coming blocks away

Just what I wanted!

The following review is for R-W12D2, which is a part of the bundle you are viewing.

Upgraded from a P3 to the new Type-R because i wanted more rms watts with my Alpine mono amp and am blown away by the difference! Got 1 12 running at 1ohm and it sounds like 2 12's in my trunk. 100% satisfied!

Great sub

The following review is for R-W12D2, which is a part of the bundle you are viewing.

I got this sub when I realized I ordered the wrong one but I can’t even complain. The bass this thing puts out is insane, normally I run 2 10s but just this single sub in a ported box is perfect. Couldn’t be happier

Blows anything else in this price category out of the water.

The following review is for R-W12D2, which is a part of the bundle you are viewing.

Bought this to replace my 1 year old Type S. My daily driver is a 2007 Chrysler Town and Country (Hey I got kids and they haul crap). I just wanted a little more than what the S was giving me. Got way more than I had hoped for. I thought I would get about double the sound. Nope its way more than double. I have this matched to a Pioneer GM D8601. Puts out (True) 800RMS @ 1ohm. Installed it today and got it set up. I dont do the break in ritual some people live by but I do take it easy for the first hour. Then retune and go all out. I must say for 1 12 in a 1.5cuft slot port in the back of a minivan sounds like I got way more than what I do have. Got a buddy at work work running 2 12' JL W3s and I cant wait to run the db meter with him to see how this compares. I know vehicle makes a difference and box but hes got those in a Tahoe in slot ports and they dont hit as hard. So heres my Pros and Cons....
Pros:
Way under priced (For what it is should really be in the 350+ range)
Very well built
Love the new look
Packaging is solid
Puts out way more than expected
Comes with jumpers

Cons:
Only 1 The included jumper wires.
I run 8ga speaker wire. Why? Mostly because I can, but I do notice a difference in responsiveness and also amp runs way cooler. But that being said the included jumpers have cheap banana ends on them. When I put the 8ga into the push terminals it makes the banana only go half way in. Was a little worried about them popping out so ended up using the set that I had from my type S that seemed a bit sturdier. Plan to rework inside the box and just make my own jumpers to eliminate the potential problem.

Alpine R12D2 Subwoofers

The following review is for R-W12D2, which is a part of the bundle you are viewing.

These subs are monsters unreal bang for the buck! I am running them on a JL1000 mono block amp and all I can say Is ouch!! They hit so hard in a spl ported box 1.71 cubic ft of ported air space hits harder than 2 15’s!!! I highly recommend these subs if you want shock and awgh thunderous BASS
