Slim subs big bass best bang for the buck.

The following review is for a previous version (Reference 1200S).

I would absolutely recommend Infinity Reference REF1200s they require less than a cubic foot of air space. I am very impressed with these subs, the box I have them mounted in is 4.5" wide. They bump very hard I love them. I have them set at 4 ohms on a 250 watt rms amp. They do exactly what I was hoping for. Great value great product. I was skeptical of slim subs in general but being that I have a crew cab Silverado I had limited space to work with. The mirror actually vibrates and I can feel the bass hit. More than I expected for sure.

Great Subwoofer

The following review is for a previous version (Reference 1200S).

This subwoofer hits harder than I thought it would. I was looking for great overall sound, not overkill. This subwoofer worked out perfect for my application.

Great subwoofers

The following review is for a previous version (Reference 1200S).

These subs sound amazing. They shake the truck and hit hard. For shallows I am extremely impressed. 2 12" with a JL 500 watt amp matches them perfectly. Would recommend for awesome sound.

Solid sub

The following review is for a previous version (Reference 1200S).

Good sound and doesn't require alot of power, but most importantly to me fits nicely under back seat of my double cab tundra.
