Great value, great name and great bass

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

Slams!

I havent had a sub since the 90s. I installed this with an Alpine mono amp in my son's cx5. I'm absolutely blown away at how deep this sub pounds, just floored. I don't even like rap, but this sub makes it enjoyable. I have it in an Atrend sealed box and I'm contemplating buying one for myself now.
