wow

The following review is for SWR-1242D, which is a part of the bundle you are viewing.

ok to start off. I like to play my music hard and loud. I put these through a lot and there still going. I have them in a slot ported box about 3cu ft.
I have two of them 4ohm wired parallel at 1 ohm.

Amazing Sub

The following review is for SWR-1242D, which is a part of the bundle you are viewing.

Great quality subwoofer. I have this hooked up to a RF Prime amp and it hits hard. Have yet to see any Cons with this sub. Shakes the whole car but sound is definitely high quality as well.

The following review is for SWR-1242D, which is a part of the bundle you are viewing.

Bought these 6 months ago and had them professionally installed. Sound great but one of them already blew. Definitely a disappointment there.

Type R

The following review is for SWR-1242D, which is a part of the bundle you are viewing.

I bought this sub about 6 months ago. At first, I had it running on the stock amp (about 60w rms) in my Cobalt, enclosed in a 1.25 ft^3 sealed box. As one could imagine, it just wasn't loud enough, so I bought a ported box (also from this site) and added a Fosgate amp. I am a guy who enjoys his low notes, and the Type R delivers great low end response! Overall this is a quality product (as is everything Alpine has made) and Sonic is the best site to buy from. I would highly recommend this sub! Combine it with a good 500w amp in a ported box, and you will NOT be sorry.

Greatest Investment Ever.

The following review is for SWR-1242D, which is a part of the bundle you are viewing.

OMG! Ive been in the car audio game for two years. Over the years ive had everything from cheap to expensive, one to four subs, ported sealed all of that... Finally decided play with the big boys and get nothing but the best.

Super Duper Bass. I have just one in a ported box paired with the Rockford Fosgate Prime R500-1. Perfect Combination. If U Only Want One Get This Pair! Wont B Disappointed.

a good all around sub

The following review is for SWR-1242D, which is a part of the bundle you are viewing.

The alpine type R is a sub that nobody could be disappointed with. The type R will play very, very loud and still remain clear. I have a civic with the sub bumping i am unable to light a lighter in the car because of the air vibrating (I only have one), I would recommend this sub to anybody.

sounds good in my single cab

The following review is for SWR-1242D, which is a part of the bundle you are viewing.

I have 2 12" dual 4 ohm in my truck in a custom box I made, internally braces and sealed all the way around. Even though this box was made to specs and solid as a rock I wish they could go a little deeper. But for what I payed these are great and they still hit deep enough to shake windows when I pull up somewhere. Overall this woofer is very versatile and sound good when in the right box.
