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

I have had these subs for over a year now and they still bump! I am running 2 12WD4 in a custom ported box running 1800W RMS to both of them at 1ohm with 1G oxygen-free wire and a big 3 upgrade. With this set up my windshield flexes like crazy and the truck sounds like it wants to fall off when I push them to their full potential. You tune them right and they will go off! Absolutely worth the price!!!
