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!

By Angel on June 28, 2025 Checkmark Icon Verified purchase


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.
