Lepai LP-2020A+ Tripath Class-T Hi-Fi Audio Mini Amplifier with Power Supply is rated 4.4216 out of 5 by 287.
Rated 5 out of 5 by from Great little AMP at great price!Love this AMP! It has all the features needed for my Garage application. I did not need a 10,000 watt AMP. This is a great little amp at an excellent price. Shipping was fast from a reliable company. I am using a AM/FM/Cassette/CD Player out of a SUV with 4 Speakers and this AMP in my Garage. It is loud and proud. If you are looking for a simple solution at great price... buy this amp.

Rated 5 out of 5 by from Killer amp with larger power supplyWas disappointed until I purchased a 3 amp supply.Think about it - 2 amp x 12 volt is 24 watts. Can't get 40 watts of output with 24 watts of input. Maybe it is actually 20 RMS total, but I can tell you with a larger supply, it has a LOT more output before it goes into protect mode.

Rated 2 out of 5 by from Clips easily with BassI bought this for a pair of Polk's R15s I had sitting around. Thought it would make a great desktop PC speaker system. Its OK until you want to raise the volume over half way with some added bass. Then the little amp seems to quickly degrade and clip, even cutting out on heavy bass. The Polks can use as little as 20 watts and as I said, low to middle volume the little amp can do OK. But don't think it can run much in the way of speakers other then small bookshelf ones. This leaves the abilities of the Tapai 2020 a bit handicapped. My feeling is this amp is more in the 10 to 15 watt realistic output and not 20. Even though its cheap, I would opt for something more just to be able to run bigger speakers at higher volumes.

Rated 5 out of 5 by from Exactly what I was looking forInstalled this amplifier (and four SAT-BK speakers) as the music system in a small coffee shop. Just needed an amplifier, but I must say, having the tone controls is an added bonus. The coffee shop owner is extremely happy with his new inexpensive "surround" setup!

How do you wire this Lepai LP 2020A to car stereo? I am setting up a car stereo with large speakers in my garage. Your video shows how to wire speakers but how do you wire a car stereo into amp? Thanks, Charlie

Can I use this amp for a motorcycle as it states it can be used in an "auto" project.

Asked by: hardley
You will need a converter to use it will DC on a motorcycle but it should work. You will also need to make sure it is out of the weather.
