cant be beat

I was able to replace my factory blown sub in my 2002 Tahoe with this one. It fit right in the factory box behind trim panel. I added a JVC KS-AX3201D cause I didn't want to go crazy. And I couldn't be happier.

Wow

Im running this sub in a .7 cubic foot ported box in a single cab ford ranger. Just in the break in period at half volume, you can tell this thing is nasty! Im pushing it with a sound ordnance M1500, and its power hungry. For sure recommend this. Cant wait to crank it up!

GREAT CUSTOMER SERVICE

I love this company....very easy to deal with and never rude. Either I ordered the wrong part or they sent me the wrong thing. I called, took me a little time to get through. But my problem was solved instantly no if''s and's or but's (lol) I would recommend Sonic Electronic to anyone.....Thanks guys.....M Youngblood

Powerful little sub

I bought this sub ti fit into the factory sub in-closer of a 2014 Jeep Wrangler Unlimited. It is a lot deeper then the factory speaker so you will need a spacer to make it fit.
I have a Polk Audio 5 channel amp with 400 watts of power going to it at 2 ohms. It could handle a lot more power. Don't be afraid to give it some juice.
I am very happy with this purchase. It is night and day from the factory sub hooked up to the same amp.
It is pretty good for Rock music.
I don't play a lot of Rap so I really cannot comment on that.
I do not thank you will be disappointed as long as you give it enough power.
I would definitely recommend it!

Cant go wrong with Alpine

Solid construction and fit perfectly in my tight space for under the back seat of my hummer. The price from Sonic is unbeatable. I only gave it 4 stars for durability because I have only had it a couple of months I can't really say its durable until I have had it for a while and I rarely drive the vehicle so it doesn't get pushed.

Great subwoofer!

I put this subwoofer in a small sealed fiberglass enclosure. The type r subs have great specs for their small size. The cutout diameter and mounting depth are smaller than most other 8" subs, but they still perform wonderfully. I am particularly impressed with the surround design. It allows for a lot of excursion. These can take a decent amount of power. I also have a kicker comp rt sub that i tried in the same enclosure. I prefer the alpine.
