This is a like new Amp. Only used to test distance which get out all over the world. Using it ideally, dead key 1-2 watts in is the safest. I get 850-1000 watts out. If you want a basestation the 100 power supply 110 volt is perfect use around 14.5-15 Volts for safety of the amp. As you can see the warranty stickers are still in place. Also contains a remote if you use as a mobile and a jumper cable. Sold as is and no return on electronics. Ask any questions before you hit buy. This is a big heavy amp and power supply. Shipping via UPS tracking/signature is $60.00.
