American Sound ConnectionUniversal Car Stereo Vented Port Single 12" Alpine S-W12D4 Type S Car Audio Subwoofer Custom Sub Box Enclosure Package New Without Amp

I have always been a big fan of Alpine head units and subs. When it comes to amps, it’s Rockford Fosgate.I needed a dual voice coil, 4 Ohm sub that I could wire down to 2 Ohms.I purchased this 12” in a ported box because I knew I would NOT be disappointed.I am even more than satisfied with this sub & box combo than I expected! I’m running 690 watts RMS into this bad boy and it POUNDS!!!I was on the fence at not using two twelves but my opinion has changed.Excellent product, I highly recommend it. Fyi, I rewired it in parallel to bring it down to 2 Ohms. Make sure you know what you’re using to power it so Ohms match.

Fast shipping.. too loud for me. But thats wayyy better than being not loud enough. Wont need an upgrade for a long time.

The subs came package good but the sub that was installed was bridged at 4ohm I Redbridge it at 2ohms and they were held in by 4 screws .but they sound great.

Hold the basss

You know when you get excited about something, and you schedule things, and get everything squared away, and you get the product, and it's trashed?Kinda sucks.

For a 10, this thing pounds!

Alpine products are amazing but for some reason this one wasn't when I received my system I got it installed and no sound was coming out come to find out it was Bridge wrong from this place then when problem was corrected the system worked for a lil over a month with the smell of burning wire and never again did my system worked

Sounds great. Looks great.
