ksc-sw11 remote
RANA on 03/03/2018 5 star rating

hi i need a remote for my ksc-sw11 can this be purchased seperatly

Really pleased
Dean Carr on 09/02/2018 5 star rating

My daughter wanted a sub for our Audi A4 convertible.Due to obvious space restrictions,we settled on the Kenwood underseat sub/amp located in the "ski hatch"What a fab unit,really enhances the Audi Concert stereo unit especially when playing Capitol radio,which seems to have extra bass.It's never going to win any competitions,but meets our needs perfectly

Excellent hidden sub
Jason Croysdill on 12/01/2018 5 star rating

First, delivery from the company was very quick, and very well packaged. Faultless. Now for the review on the sub. The first thing I noticed on unboxing this was how heavy and well built it was. It's pretty much all metal so a big thumbs up for build quality. I installed this in a 2006 Citroen xsara picasso. After removing the underseat tray under the drivers seat (passenger seat has the car battery underneath that seat), I set about the install. Now I was going to pay to have this installed as I have not dabbled with this sort of thing since my late teens, but I needed of worried. Hardest part about this is routing the cables from behind the stereo to the actual sub, however please note you will need to purchase some RCA cables if you don't want to splice into the speaker wires. It's simple connect to power (I used spare lead at back of CD player) connect ignition wire, connect RCA leads and then ground it to a suitable point on the car as close to the sub as possible. So all that was done and the sub was set up, time to test. WOW......this just makes everything sound so much better, I have this set at under halfway on volume on the sub and it is MORE than adequate. It packs so much more bass than I thought it would. It is not boy racer loud, but that's not what I wanted, but it is loud!!! And I definitely feel it through my seat while driving. If you don't have space or want a big sub in your boot, you will not go wrong for this price. Definitely no regrets on buying this at all.
