By far, THE best lowpass sound in a pickup, ever. As in, EVER!!
Had this installed in a customers 2015 ram 3500 Mega Cab here at Lone Star Dodge Chrysler Jeep. Customer had 3X the cost of the Stealthbox in audio the Stealthbox replaced. I had never even heard of a Stealthbox, but yesterday, let me be very clear: this truck woke up and displayed a bass tone so low, I could feel it, but couldn't hear it. Once you hear a quality so rarely observed as this product, you will become a different person when it comes to what is acceptable. This stealthbox simply put in my opinion is the single best place you can spend for the price. You will not be disappointed. This thing is just insanely well designed. Ok I'll shut up now. I am ordering one for my truck ASAP.
Pros: Bass tone lower than any other product I've heard. Tight, I mean TIGHT bass response. Quality is simply UNMATCHED. Fit and finish is well rounded out for an unmatched installation.
Cons: The price. Too much, but how do you put a price on a speaker box designed by a couple of NASA Aerospace engineers? I'm 100% converted. After the customers truck left, I don't even want to drive my truck until I get this thing installed. After seeing the final fit, then hearing this system, nothing else will satisfy you.
