Great sub!

The following review is for SW-SACL12D4, which is a part of the bundle you are viewing.

This sub is amazing, sounds great when given enough power! Put this sub in a ported box tuned to 32hz, give it the right box and good amp and it’ll sound great!

Good value and sounds great.

The following review is for SW-SACL12D4, which is a part of the bundle you are viewing.

I bought a JL Audio W3 12” high output box and sub package and the JL sub blew within 2 minutes of use. Powered by an Audio Control 1.800 . No clipping and gain just barely reached 1/2. I know, I know, it was too much power. But really a $450 sub and has a paper/ plastic voice coil.
We bought this sub (Sundown SA Classic 12”) and it slams. We put it in the JL HO box and it fit. Just barely. I did have to sand the opening just a bit as the Sundown needed 1/10 of an inch bigger opening. At half the price of the the JL I learned my lesson. This sub with the AC 800 watt amp flexes the roof of the car pretty good. Sounds great. Tight clean bass.
