We mounted this Pyramid Amp inside a 6" PVC pipe, with 6" PVC elbows on each end. Mounted two waterproof 6" 100 watt speakers to the elbows, wired AMP to cigarette lighter or accessory power plug. Can be used on any vehicle that has a cigarette lighter or accessory power recepticle. (Cars, 4-wheelers, etc.) We strapped ours to the front rack of our 4-wheeler. Ran audio input cable to an MP3 Player. We use a waterproof pouch to store MP3 Player when on the go, also mounted on the rack. Works great, sounds great, AND... it's portable. Whole project cost us about $150. This particular amp was also available at other sites, but Overstock.com had the best price.

Worked well, just used for one subwoofer. Easy to install.

I bought this amp for the sole purpose of installing it in my cooler radio to drive a Polk Audio 8" 360 watts/max subwoofer and the compact size and power it brings couldn't be more perfect for my application. So far this amp not ran hot, stays warm but nothing extreme. The only thing I thought could be better is that the power/remote/ground wires you have to hard wire, no place for screw in terminals. Other than that I would recommend this to anyone wanting a low amount of power at such a cheap price.

I just love the sound this amp puts out.Bought it for my s-10 to hook up my rear 6x9's and the sound is just awesome. Planning on getting another one for the fronts. very crisp and clear sound. simple to hook up and the size is perfect for small vehicles. LOTS of sound!!!

I bought this amp to power one bass tube for my little Honda. If you don't need a lot of power this is a very cost effective option. I am quite pleased.

awesome bass sound!!!great price,great value!!! my son-in-law loved it.

Just got it a couple days ago...hooked it up and it works great....a little weak but i guess you get what you pay for. Otherwise great buy!

An excellent choice for cheap power. Easy to install, and the controls are very accessable. I have two, one for my tweeters, and one for my subwoofer and the sound is very clean, even at high volumes. A great choice when you are on a budget and looking for great sound.
