Alpine SWT-10S4

Sound great in my sealed enclosure. Have 2 in my regular cab Sierra.

Great subs for the money

These subs are great for the cost of them. They hit harder than I expected for being shallow. My wife can hear me pulling into the driveway when she is inside with the tv on! I can't speak for their durability, but they look to be built really well. I would definitely recommend these.

Great for the price!

I built a box specific to the sealed box dimensions it requires. put it in my gladiator, and I am very happy with it. exactly what I needed for the cost. Yes, could I spend more and get more, sure. but this was exactly what I wanted.

Not worth it

Have 2 in a 2012 Dodge Ram hooked up CORRECTLY, nice to have them under the seat and out of the way. They do not BANG hard. If you buy the right door speakers and spend the same amount you'll get the same bang.
