Nice box

The following review is for 12SQL, which is a part of the bundle you are viewing.

This is a really nice box. I have a Boston Acoustics G5 in it and it pounds!!! I wanted to save space in trunk by switching to small sealed box instead of the big ported I was using previously. I thought I would be taking a hit in SPL but surprisingly I didn't. Just a gain in SQ. And I gained about 50% more trunk space.

The following review is for 12SQL, which is a part of the bundle you are viewing.

I just received two of these boxes today. I put them in my 2017 Chevy Camaro. I have 2 Rockford fosgate P 2's and I have a Rockford fosgate T750X amp pushing them. Have them wired at 1 ohm. Man my system sound so good. If you dont have much trunk space this is the way to go. And the Rockford fosgate setup is amazing.

Good value

The following review is for 12SQL, which is a part of the bundle you are viewing.

Great box for the value. I have a JL 12w6 in it and it sounds amazing. My one issue was the aesthetics, it arrived looking like it needed a bit more carpeting but for the price and sound quality i’ll take it.

Great value, great name and great bass

The following review is for S-W12D4, which is a part of the bundle you are viewing.

If your looking for a budget happy bass build you'll be happy with this one. I purchased one of these not thinking about my box being a single 15" box. Well I had a piece of solid hardwood flooring that I cut a 12" face out of and put over the 15" whole. I have an Infinity Reference series 611a amp on this thing turned almost halfway on the gain, nearly full on the bass boost and 3/4 on the variable bass optimisation. I ported and tuned the box myself and people think I got two twelves instead of one. Pros. Alpine Great price Cons. Don't hit the low end bass notes as well
