If you are looking for a ear drum bleeder this isn’t for you. The unit does very well and is small enough to fit nicely under the passenger seat, even if pushed all the way forward you can’t see it from the back seat(mini coop seat). It doesn’t have a bass boost and as I mentioned in the "title/subject" it is under powered, it might be actually a 250-300, it still does a great job with my stock speakers. If you have a small car and you want to add an amp to improve the sound of your ipod/pad/touch or tablet and you want it to be hidden, this is a good unit(unless you want bass ear bleed).
