Unbelievable Quality

The following review is for 8W1v3-4, which is a part of the bundle you are viewing.

After a lot of research, I’ve come to learn about JL Audio, this subwoofer just reeks quality, it’s a shame to have to put something so nice under a seat and hidden from view. But as we all know it’s about sound too and that is where this sub really shines,
I originally was going to buy a self contained subwoofer amp combo, boy am I glad I didn’t, this sub rocks in my cut down box with only 0.35 cf of interior volume, that was the recommended cubic feet by JL Audio,
The fit under the passenger seat was perfect on my Sprinter Van and the bass is awesome.
If I ever buy any speakers again they will be JL Audio, if I wouldn’t have already bought JBL’s component speakers and Polk tweeters, JL would be my choice. Plus who knows, I still may change out the JBL door speakers for JL Speakers, the amp I’m running this sub with is a Alpine MRV-M250, which seems to be a perfect match. The price at Sonic beat out every other vender I found and also threw in a free sub box, great deal, I highly recommend.

Glad to own JL again

The following review is for 8W1v3-4, which is a part of the bundle you are viewing.

I had owned a 8W1V2-4 a few years back and it lasted quite a while until I messed it up. I then decided to go a cheaper route and get a MB Quart shallow 8. I had it for a year and decided that I wanted my JL sound back and the shallow was not cutting it.

I upgraded back to the newer version 8W1v3 and placed it in a .5 ft cube ported box in my 2007 F150. I am still tuning the amp and have not reached the full potential but cant wait till it does.
