Rated 5 out of 5 by from Wow. Overdelivered.Powering 2x Dayton audio 6 1/2" Bookshelf speakers, there could not be a better budget stereo setup. Blows my expensive name brand units out of the water. Parts Express customer service is absolutely top notch. I will be buying many more products.

Rated 5 out of 5 by from Fantastic Sound and Power !!!I bought one of these at the open box price and I would have been happy at twice the full price after using it. I've tried Bose 301's, Teac LS100 bookshelf and others. Any speaker I put on it sound really good with plenty of volume in my garage. I only used the supplied power block and thought it was good. I plan to try a higher power block but so far if I only used what came with it I would be happy. Bass and treble adjuster worked well, didn't get too hot and the sealed aluminum case will keep out garage dirt. I can't wait to get the 4 channel unit. If you are reading this, you're curious. Trust me, WAY WORTH THE PRICE !!!

Rated 5 out of 5 by from Smoking outdoor sound system powered by this amp!I had been reading the reviews on the LP-2020A+ and pulled the trigger last week when there was a $15.00 open box on Parts Express. I had picked up a pair of Niles OS-10 outdoor speakers at Goodwill for $10.00 and hooked the amp & speakers to my iPhone. I usually rip at lossless or very high bit-rate. Wow! The sound is amazing and very much loud enough to fill my backyard with great music. Highly recommend this little amp. You will not be disappointed. Oh, and the blue light around the volume is great when I'm playing music outside after sunset. Buy this!

Rated 5 out of 5 by from Perfect choice for small (and desktop) speakersI'd heard good things about these small amps, so decided to pick one up to power the pair of Jeff Bagby's "Quarks" I'd built for my wife's office. What a pleasant surprise! ...this little amp drives the small speakers cleanly and with great clarity, and the tiny footprint made placement a breeze Absolutely, I'll pick up another for other similar projects and would definitely recommend to a friend.

Wanting to use this in a portable application w/battery. Can you recommend a battery rating to get 6-7 hours of use with a fully charged battery? Also, what product to you recommend to make this unit connect to MP3 device using Bluetooth?

Asked by: tc78130
A 7Ah SLA battery should last that long without a problem. We have plenty of Bluetooth receivers that will plug into this amplifier as well.http://www.parts-express.com/power-sonic-ps-1270f2-sealed-lead-acid-battery-12v-7ah--140-366http://www.parts-express.com/battery-powered-bluetooth-wireless-audio-receiver-with-power-supply-black--320-355

15 Volt Supply? The chip is rated to 16V - anyone run one of these amps at 15V?

Asked by: Anynomouse
I think I answered my own question. They have an over-voltage circuit that is supposed to kick in at 14.4, but one user said it wouldn't run on 13.8V.

I have 2 500 watt speakers would this work on this reciever?

Asked by: bmbmb
This will power them but your output will be limited. Overall output will be determined by the sensitivity of the speakers.

I'm trying to create a cheap outdoor movie theater. I'm thinking of pairing this amp with a pair of the Dayton 4" outdoor speakers (part # 310-030). Will this combo be able to deliver decent volume for outdoors. I will look to add a sub in the future.

Asked by: Mitch A
This combination should work relatively well as long as you don't crank the bass knob all the way up. Keeping the tone controls bypassed will allow for more output, you won't get much below 100 Hz from these anyway.
