Alpine SWR-1243D

great sub, good deep bass

Pros: deep bass, can be loud or soft and sound good, box doesnt matter, sounds good in sealed or ported, only need 500 watts to get it pounding.

Cons: will blow easily if you try to run it close to max watts (stick with rms), doesnt have the high notes that other subs do (this is more of a rap sub than a rock one).

Excellent product

I have this sub in a sealed box in my truck running at full power and it sounds very good. It doesn't distort at all and the bass hits very hard without any distortion. Highly recommended, I'm very happy with it.

Awesome

I love these subs. I installed these and ran each one off its own amp. I'm only giving each one 500w but these things bang.

You wont be disappointed

Have had mine for at least 3 months or so. I have an 1100 watt peak 550 rms amp hooked up to this and I am not gentle with it. Just one 12 in a custom ported box and this blows away my friends two kicker CVRs. Definitely worth spending the extra buck to get these. You wont be disappointed.

guy buy for the price

I bought 2 of these subs with a hifonics brutus 1200 rms amp and it was perfect for these subs.

Awesome subs

Put them in this afternoon and they bang hard

Alpine 4eva

I have 2 12s wired down to 1ohm and I almost forgot what these sounded like! I owned 4 ran off 2 1500.1 kicker amps a couple years ago and they were dual 2 ohm wired to 1. Dual 4 put out the same head pounding bass, extreme lows with little or no distortion at high volumes. RE 1500.1 bridged are runnin mine. XS 1200v cell with .5 farad cap and yellow top optima for SERIOUS power. Sealed enclosure for my 97 continental.

Hard hittin

Bought this along with an RF Prime R500.1 (528RMS).
At first I had this in a sealed box and I was happy. Then I got a ported 1.8 cu ft box and this thing hits so dang hard. When the back seats are down it shakes my winshield and side mirrors like crazy. So many people ask what I have in back and they are amazed when I tell em its only 1 12". This thing out does 2 kickers easily. Almost nothing can compete with this sub in its range. The only thing that you have to watch on this sub is the low lows. After playin rack city at max volume they started to smell a bit. For all other Hz this thing is a beast.

Make sure you get a box designed to spec!

I had one alpine type r in a walmart box and was very disappointed. So I decided to get a second one and put them in a ported box designed to spec. WOW what a difference. I was bumping so hard my rear view mirror fell off! I would definitely recommend this sub just make sure you buy a ported box from sonic instead of settling for a walmart box!!

Alpine Type R

If you want loud get these. They dont change notes very well between high and low hits but they are still loud. If your lokking for everyone around to hear you get these. Two of these in a ported box is all the bass you would ever need.
