PN5.640D 640W 5-Channel Picasso Nano Class-D Amplifier

I’ve got 3 of these. For the money it’s tough to beat. It runs 4 cabin speakers and a sub with no problem. What I don’t like is the screw type connectors for the speaker wire and the power/ground wires. I’m not completely pleased with the final look of this but it’s secure and assures me the power wire stays isolated. Overall, I have 3, so I’d buy a 4th

love the small size of the amp, however its very powerful with external bass boost controller for easy access to bass level. well worth the money

This amp is awesome! Good clean power and it's compact enough to fit in tight spots ( under the seat of my 2000 SS Camaro, not a lot of space there!) good looking, and very reasonably priced as well! So far it does not get hot at all, like it's not working hard at all to push my 2 sets of Rockford Fosgate separates and a DVC RF 10" sub wired for a 2 ohm load to my 5th channel. My only problem, and reason for docking one star, is the connections. I do not like the way the RCA jacks are set up. and I've had issues with the other end of the amp where the speakers and power/ground too. they're crazy close together making it hard to connect wires and get to the screw that secures the connection. Not a deal breaker, I'd buy it again! Just putting it out there, it's not the best amp I've wired up, and I have done a few! Besides that, it's pretty dang awesome! \m/ \m/

Lots of power from a little Amp. Never gets very hot. I use it on a Jeep Wrangler and it is a perfect addition.

So much power from such small amps. I liked it so much I bought one for daughter
