Slim subs big bass best bang for the buck.

The following review is for Reference 1200S, which is a part of the bundle you are viewing.

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 Reference 1200S, which is a part of the bundle you are viewing.

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 Reference 1200S, which is a part of the bundle you are viewing.

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 Reference 1200S, which is a part of the bundle you are viewing.

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

Nice sounding box but abit tall.

The following review is for NE121P, which is a part of the bundle you are viewing.

Great sturdy box, carpeting was nicest done only thing i disliked about it was its hight it too tall my trunk is 14.75. But this thing is 16" tall had to cuz the foam that was under the mat to make it barely fit and also re.oved the back seat...it was worth it though, im running a rf-p3d2 12"
