Soundstream PN5.640D Picasso Nano 640 W 5-Channel Class D Digital Car Audio Amplifier

Installed this to the underside of the center console lid in my '95 Wrangler. Fit perfectly! Drives my Rugged Ridge 6 speaker sound bar and 2 JBL GTO6428 4X6"s for excellent mids and highs as well as the 2 down fire Kicker 10" subs from American Sound Connection for incredibly "tight" bass. All from one "mini" amp. I have not had any issues with the amp overheating or "clipping" that other reviews have mentioned and my amp is in a very small space with almost no air circulation.Pros:5 channel - Drive entire system with a single amp.Built in adjustable High & Low pass filters - Keep your speakers within their optimum frequency response range and reduce distortion.Remote Control for bass boost. - Adjust on the go. Great for amps installed in a hard to reach area.Seperate Gain adjustments for "front", " rear", and "subs" - Remember that "gain" is NOT VOLUME! It is meant to properly match the line level voltage from your receiver. The higher the "gain" the more distortion is introduced. If you want it louder, you will need an amp with more wattage (and a larger space to install it).Cons:No low (RCA) inputs - Pig tails are supplied with the amp. This makes your "gain" adjustment all the more important.Overheating - I don't have this issue but , some have mentioned it in their own reviews.Inputs and adjustments are on the same side - Good for a more simplified installation but it makes it more difficult to adjust the HPFs, LPF, and Gains. At least in my case it did because I installed the amp upside down and was limited with ways to run my wires.This amp is perfect for the setup I choose, providing absolutely ear pleasing sound. It delivers crisp clean highs, perfectly pitched mids, and NOSE TICKLING bass.I have used Soundstream products for over 15 years without a single issue and highly recommend them, including this amp.Enjoy!

Don't be fooled by the size, this little sucker packs quite a punch! The form factor was perfect for me, as I was able to (easily!) fit it under the passenger seat (I didn't have much room to mount it anywhere else).Right now it's powering two 6" door speakers, two 4" door speakers, and 2 x 10" sub in the trunk. Those door speakers are all my car was originally outfitted with, so I needed an amp to get the most out of the (relatively) small sizes, and this one didn't disappoint. The sound quality is great, and I can hear my music clearly even when flying down the interstate with the windows down. Once I added in the sub (Rockford Fosgate Punch P1-2X10) and adjusted the built-in crossovers, my system sounded fantastic (making my friends jealous).The sub presents a 2 ohm load, and the 350 watts from this amp is plenty of power; if I crank it up it can still get "uncomfortably loud". It's not going to be shaking the vehicle across the intersection or the houses 2 blocks down your street, but that's not really what I was looking for in the first place.Installation was pretty easy (again, especially thanks to the small size). There are screw terminals for the power, ground, and outputs, but the RCA inputs have to connect to these funny little wiring harnesses first. I've read some reviews complaining about heat, but after several months in the hot Nebraska summer I haven't had any issues with it overheating.If you need an all-in-one amp with a slim fit, look no further!

Junk!! Lasted maybe a month before having issues. Don’t waste your money! This amp has some major design flaws! First, the power and ground hook ups are stacked on top of one another. If you use a decent size wire, the set screw for the ground wire sticks up in the way of the power wire. Which will eventually rub through the power wire. Second, the tiny 4 pin connectors are junk! In my case, the pin for the remote wire malfunctioned. If you don’t hold the connector a certain way, the amp won’t turn on!

I ended up using this amp in my Honda Element to replace the underwhelming factory amp. This amp is tiny but cranks out some really impressive power. I have it running JBL club series components in front, 2-ways in back, and a Kicker 6.75" sub in the factory enclosure. It fits under the seat with a little bit of trimming of the plastic under there, and sounds WAY better than I thought I'd ever hear in that toaster of a car. I was a little skeptical since there have been so many big car audio brands from the 90s that were snatched up and now sell junk, but Soundstream apparently isn't one of them.The only negatives I can think of are that I don't care for the way the RCAs and bass remote plug in, but on an amp this small there just wouldn't be room for that many connections. They're a little bit on the fiddly side but they're effective.
