Hello, What is the internal air space measurement? I have 2 Type R Alpine subs, rated at 1.25 to 1.5. Thank you for your time.

Dude this thing is huge I is more than big enough for your sub's it is like 5 cubic feet

This big box is 2.25 per sideafter all displacements. Tuned to 40 but I measured 38hz.

From what I've read, that 4 ohm sub wants 150 watts RMS. That Alpine puts out 300 watts RMS at 4 ohms. You might save some money by looking for a bit smaller amp. But, if you don't overdrive the sub, that amp will work. It is nice clean power.

You've gotta contact Kicker. All I know is that he more air space you give this woofer, the more it slams. I've got 1 in a box that had 5.7 cuft of air space on a mono block amp. It crushes...!

Well I have two quantum cosmic series 12's on the 2.1500 and it sounds like my jeep is going to rattle apart. Both of my subs are rated at 1200 if I'm not mistaken . I'm happy with it's performance on both subs. Recently I bridged it onto just one of the subs and it sounds fine but it just won't tune right . But to answer your question I'm satisfied . As long as your not trying to hit on the db meter you'll be satisfied with the performance and the price

Hi First off where do you plan on putting this? Behind a the seat? Well the box should fit it is only 36" wide, the only problem I see is having enough air flow for the ports to work properly, in my rav4 I have about 3" on each side and i'll tell you when the amp is all the way up it feels like I have some type of blower in my car to move the air around this is awesome, I m using a Alpine PDX-V9 with 500 watts for this sub

The box comes with spacers to raise the seat up. About 1/2in i think. But the subs fit down in the box the dont even come close touching the bottom of the seat. I telling you i look everywhere for a box and this one is AWESOME. Ive got Alpine Type R's w/ JL Audio 1000 and its clean

I have 2 ALPINE SWR-12D4'S,THE AMP I'M USING IS A LIGHTNING AUDIO 1000.1md @ 1 ohm & they slam every time I turn the corner I be turning heads, the only problem I have is my lights dim pulling to much power!how many speakers do u have?

I bought the same amp a few months ago. I went with a 10inch enclosed Kicker for my Jeep Wrangler. It was an awesome choice. And it sounds great.

I down graded from 2 Fosgate P3's to a single sub to get a little bit of trunk space back (2006 Sentra). I think the sub sounds damn good for just one. I have it in a 1.25 sealed box, hooked up to a Alpine 500W mono amp turned only to half gain with a remote bass knob. I have nothing negative to say about the sub.

Whats the RMS on your Subs? the RMS on the amp is around 570 which means anything over 570 will make it work a little harder (Which is why they heat up). if you have good breathing room around your amp like i do then you will be fine pushing two subs off it. I have 2 alpine type S 12 inch subs hooked up to mine. Doesn't heat very much because it has air flow around it. hope this helps.

The sa12 is 600 rms and this sub is 300-1000 rms. so essentially you can push the alpine more but sundown is elite when it comes to car audio and they can take a beating. If you know what you're doing you can push the sa 12 way past 600 rms. but both are very good subwoofers.

Well didn't look up specs but if your running 2 subs I wouldn't overrun the subs rms too much. I wouldn't put more than 1200 watts on them. Over powering even though they are underrated certain songs like jeezy will burn your subs. I am running 2 jlaudio jx1000/1 awesome amp. I blew my obsidian 18 with that amp. So they are 900 watts at 12v I'm running them at 32 hertz. Loudest system I have had. I would run 1 Rockford to two if that is 1250. I also run two batteries for the two amps. I think that is making all the difference running rf 3sixty.2 whole car is dymatted. Do 4 sealed. With the two amps. These subs sound better sealed. 4 sealed on 5000 watts will sound better than 2 ported on 5000. I do prefer my 32 hertz box but you can really see what they can do sealed. Better sq. Although the sq is flawless anyway. Best subs ever man for the money. Will eat an idmax

The manual that came with the subs say to use 1.0 cubic foot per sub or .5 cubic for enclosures with a port. I have 2 in a rather small box, about 1.0 for each sub and it sounds like they aren't getting enough air so I would suggest around 1.5 each in a ported box.

"Fit" is a loose word. I doubt that you can shove it under you seats, but it doesn't take up much room and if you are going to use all of your seats one day it is super easy to take in and out with the quick disconnects. Is there is a specific place you want to put it?Ill second that it sounds better than a pioneer, you really cant beat this setup. I have owned various sub and amp combos and still prefer this overall.

Depends his much trunk you want after you build your enclosure, they recommend between 2.5-3.0 qubic feet for ported, and around 2.0 cf for sealed. This sub is a good bang for the buck but there are better subs that require smaller enclosures. (JL audio more money). I hope this helps.

No idea, sorry. I ditched the unit by selling off and getting an Alpine which is great.

Excellent, I personally think down firing subs sound better. Propped the front of my unit up 3/4" in the front with rubber feet to allow for more clearance between speaker and carpet, and help with air movement. Bought them at my local hardware store.
