Accessibility

Control your bass level from the driver's seat with an input for a wired remote level knob. The remote level knob has a 15' cable attached for flexible installation anywhere on the dash. Adding the PWE-S8 is easy with the easy-access RCA inputs and speaker-level inputs with automatic turn-on.

User questions & answers

Question:	will it fit under the rear seat,of a 2013 3500 Chevy crewcab
Answer:	If you click on the product and scroll the pictures it shows the dimensions it is 15" L x10.2 Dx 6.8 H
Question:	Can you add a bass control to this sub
Answer:	Hi, the height of this step stool is 6.8" when opened.
Question:	Does this come with an amp it shows an amp on the pics that's why I'm asking
Answer:	I suppose it could be used as a tub seat, as it is very sturdy, but because it is metal, I think that would be a bad idea. I have a plastic folding stool, also from Amazon, that I use in the tub when I shave my legs. It is easy to clean, several inches taller, and in no danger of rusting. I am short, so I have no trouble getting on and off, but even I would have a problem with the metal stool.
Question:	is it possible to upgrade the amp and sub down the road? like type R alpine sub? or maybe keep the amp with type S alpine sub
Answer:	It fits any cassette player, I have tried it in 4 vehicles. As for the iphone x I am not sure, if it uses a standard headphone jack it should work.
