looking to add some base, and the reviews are good for this product
Sergio G on Oct 9, 2016

compact single unit small
Luther H on Jun 29, 2015
Does the Unit get hot easily? Thinking of mounting it inside the back seat cushion area of my car and I don't want it to overheat
Lawrence R on Mar 31, 2015
Best Answer: It doesn't get hot much in the back of my pickup truck,i mean as any amp it should be in a well circulated area,i don't think I would mount any amp inside a seat imho,if you hook it to the back seat you will still get the benefit off the Bass , a Sub deal in Wave length more then a Bass speaker.. but for the price it is hard to beat

How good will this subwoofer work if installed in the trunk of a car?
Earnest F on Jul 11, 2015
Best Answer: I do not know. I was going to install it in my pickup truck and it was too large to fit anywhere in the truck. Had to send it back.

I want to replace the kicker sub in my crosstrek because it is overbearing and cant be controlled. I can't even hear lyrics in the music. Will this sub be a good replacement giving good clean bass that could be controlled?
David H on May 19, 2015
Best Answer: Yes this sub is more mellow than what you have it sounds like. This sub just enhances your factory speakers, not over bearing.

is this compatible with the Boss BV9986BI?
Brian on Jan 14, 2015
Best Answer: Yes, as long as the unit has a sub pre-out which it seems it does. You may also connect it using high level speaker outs of the BV9986

Does this turn on automatically when a signal is sent through the rca cables or do i have to run a wire for a switch and the wire for the input gain?
chance s on Oct 15, 2014
Best Answer: Hello Chance,

Boss designed this unit a bit strangely; Although it does have a 'Auto-Turn On Switch', this refers to the use of the REMOTE connection, reference page 5 for details. To the point, this unit MUST have a Remote Source.
