Blaupunkt GTb 8A 150-Watt 8-Inch Preloaded Active Subwoofer System

Being a musician, whenever listening to music, movies, or just plain TV, it has to sound good or I don't listen to it. Our travel trailer sound system just did not have enough depth or body to the system so I thought these would fit the bill and I couldn't have been more right! Simple install (about 30 minutes) with the included wireing harness, and works great! Actually too much power fpr the trailer (32 foot trailer) but with the signal input controlled by the head unit output, once the volume level on the sub was set, it is perfectly balanced, no matter what the volume is.For the money, it can't be beat. For the quality, you won't find better at twice the price. Size ?? Perfect for small spaces and should even work great in a small car or behind a truck seat. Plan on testing this out as soon as I get another wiring harness so i can move it from the trailer to another vehicle when not using the trailer. Once again, great value, great unit.

Not much bass. It did not work for us.

Used to be a serious car stereo enthusiast. Grew up a little and wasnt looking to blow my doors off.This sub is perfect. No so great on the low end but enough bass to fill in the rest of my system. I have a subaru outback wagon and this thing sounds pretty darn good for a all in one unit under $150.

Easy to install, plenty of power for my purposes, simple external adjusments and controls, clean sound. Installed in my motorhome, really enhanced the existing 6 speaker sound system. Would definately recommend to a friend!

I highly recommend this product to the people that want a subwoofer but needs the trunk space.The installation is very easy and it comes with everything you need, except the RCA cables to connect the SW to the stereo.It comes with its own amp and several options to configure it.Recomiendo ampliamente este producto a las personas que desean un subwoofer pero necesitan el espacio en la cajuela.La instalacion es muy sencilla y viene con todo lo que se necesita, excepto los cables RCA que conectan el SW al radio.Viene con su propio amplificador y muchas opciones para configurarlo.

I was looking for something to add a little depth not to compete at stop lights or to rattle the bejeebers out of my license plate! Installation is easy and it's small enough to fit where I need it to. For what I paid IT'S AWESOME and It's capable of providing more bass than I want. VERY PLEASED!!!!!

This thing is a high $ paper weight. I bought this to add a little bass to my wifes factory stereo. I added a nice Pioneer head unit and left all the factory speakers intact, The factory 6x9s in her Buick put out just as much if ot more bass then this 8. I will be returning it and buying her a Kicker Comp 10, box and amp all for around $150.00 and I know for a fact will have more bass to deliver then this item. Buyer be ware. You can easily buy a single woofer box small enough and a good sub to get more then this unit offers for around the same price point.

This is a great inexpensive way to round out the bottom end of a factory or lower-powered audio system. It quickly runs out of gas at higher volumes, but sounds great at low-to-mid volumes. If you're looking for an inexpensive way to add good, thumpy bass to a factory setup, this is it. If you are looking to rattle your neighbors' windows, or something to keep up with higher-powered aftermarket stuff, this ain't it.
