PN4.1000D 1000W 4-Channel Picasso Nano Series Class D Amplifier, Gray

Ok, the amp is great. I installed it on a 2013 Ultra Limited and place it above head unit. I using it on 4 6.5 DS18 Pro 4 Ohmz speakers and 1 tweeter on my left side replacing my Ambient temp gauge. I tuned the amp for high frequency on the upper fairing at 1000 MHz and the lower at a 500 MHz at 23.6 volts gain. Speakers are rated for 250 RMS but only pushing 140 with above values. Sounds great and very clear and was able to get some bass out of them. I did make all my cables including RCA due to the length of stock cables. Is a tight fit but will fit fine. Over all extremely happy with the clean sound . Remember all amps need to be adjusted to get the beat sound. Hope this helps everyone looking for an amp will definitely buy it again. Also I’m only using 500 watts of the amp was my choice in case in the future I want to add additional speakers in my touring pack I currently don’t use touring pack, also amp will run cooler as well. With people that use the CB you can mount underneath the HU. I removed mine I do not use it.

I am doing a project build on my 2010 Road Glide and installed this amp and speakers to see while I was able to return if I did not like quality of sound, I was happy with everything and disassembled bike parts to send to painter, I then assembled newly painted parts and reinstalled this amp and speakers only to find it does not power up now, I have checked everything even disconnected radio and speakers to see if I would get a power light, checked fuses...nothing I now have a brick Update: I am the first to admit when I am wrong and I have to say "I was wrong" for jumping the gun and writing a bad review about this amp taking a dump, after calling Soundstream and talking to the tech he pointed me in a few directions to make a few changes, he told me rather than using the frame as a ground use negative of battery, but the amp worked fine the first time around so I knew it was not that, but what he then said was the remote wire needs to have power so I knew the problem was there. To use the handlebar controls you need an adapter by Metra and there I started my troubleshooting, once I disconnected the unit from the power I had to reprogram it which then gave my power to the remote wire, end of story. This is a powerful amp for motorcycles and I will buy another one when I add the 12" to the tour pack.

I purchased this amp to install in the fairing of my 2007 Street glide.its pushing 2 DS18 PRO-ZT6 6.5-Inch 2 Way Pro Audio Midrange Speakers with Built-in Bullet Tweeter 4-Ohms 450W Max 225W RMS Water Resistant In my fairing and 2 CERWIN-VEGA! XED Series 6"x9" Inch 3-Way Coaxial Car Speakers - 350W MAX Power, 4 Ohm Audio, Durable Poly Cone & Metal Dome Tweeters, Butyl Rubber Surround, Ideal for Car Speakers XED693 in my saddle bags. I did a non bridged setup for 4ohms on each speaker and I'm very happy with the results. The gains are both a little under half way and I can hear the music clearly from a few blocks away. No distortion, or clipping. The amp fit perfectly ran horizontally without an amp mount. For the fairing to fit snug, I had to run the wiring around the sides of the amp. I do plan to upgrade the rear 6x9's to DS18 PRO-ZT69 6x9-Inch 2 Way Pro Audio Midrange Speakers with Built-in Bullet Tweeter 4-Ohms 550W Max 275W RMS Water Resistant Speakers. I was being frugal at the time. It has not over heated, nor drained my battery. All in all, I give this amp a 10 out of 10.

Fantastic amp. No issues what so ever. Didn’t even have any over heating issues after a 12hr ride on Street Glide. Amp fits under front fairing mounted on top of head unit.

I wanted to write a quick review on the amp, just to point out that an external fuse is not necessary. There is a small, clear plastic panel is accessible from the bottom of the unit and houses two 40a fuses. Therefore, please be aware of this when choosing an installation location. Secondly, the amp is discontinued, and the manufacturer only hosts the updated PDF manual for the Picasso Nano series (which already has the product removed). Other than that, I'm a big fan of this amp line. Very efficient, and compact. Quality is great, and have had no issues. Will update this review as I continue to use it. UPDATE: I moved to this amp from a Pioneer GM-D8604 ( 4ch Class-D), and have seen large improvement in the sound quality. It is currently driving 4 Kicker CS-Series speakers at 100rms without any issues.

Honestly I was on the fence with this. I wanted an amp for the interior speakers in a convertible. It takes a lot more to push those and make a sound than in a regular car. The installation was not cumbersome, it fit in the space I needed and works well. Overall there is a good value for the money. I don't think it gets too hot as it's close to the trunk and air passes through, and has not cut off!

nice amp , pleasantly surprised with quality of sound and a small package for tight spots ! very nice , will review after a few months for reliability . . so far ,Awesome ! update ,after 6hrs of usage it cuts off . still has power but no out put ,horrible design, have to remove to replace fuses ! hope thats all it is . .

Have this mounted under steering column 2019 wrangler JLU (where the factory alpine sits). Runs 8, 4 ohm speakers without excessive heat. Very happy with this amp! Have it connected to factory uconnect 7 via DS18 V5HL 5-Channel Line Out Converter. WOW loud, and clean sound. Front upper dash changed to: KICKER 43DSC3504 3-1/2-Inch, front lower dash changed to: Alpine R-S65.2 (RS652) using, Metra JP-1014 Speaker Pods. Rear overhead tweets replaced with: Kicker KSC3504 KSC350, Rear overhead woofers replaced with: Massive Audio FX4 – 4 Inch woofers. 2 home made subs in rear .5 cf sealed with Dayton Audio DCS165-4 6-1/2" powered by Soundstream PN2350D 350W. WOW!

Lots of power, sounds clean and full powering 4x infinity primus 6.5". Size makes it versatile. Price point is hard to beat.

El amplificador es más pequeño de lo que uno imagina, es de un peso considerable y viene con todos sus aditamentos para la instalación (cables y tornillos). Se tiene que comprar un buen kit de instalación eléctrica ya que al final va conectado directo a la batería del auto. En mi caso alimenta dos juegos de medios focal generando una potencia excelente para llenar este set de medios. Se calienta el amplificador pero nada de que asustarse, lo he tenido en uso por más de 4 hrs y mantiene una temperatura que hasta con la mano se puede tocar. Solo instalen en un lugar ventilado y que no estobe la circulación. Lo recomiendo ampliamente.

Incredible! I was using a Soundstream Stealth and although it crapped out, the Stealth provided great sound (especially for such a small package)...at least I thought. 4 Alpine Type R's and now they have really come alive. Additionally, the high level input on the Stealth amp would clip (distort) around 75% on the stock headunit volume...the nano can go all the way and still get a clean signal without clipping...I barley have the gains turned up. Nicely done Soundstream & thank you Amazon.

Amazing sound out of such a small amp it fit behind my deck in the dash And was easy to tune and set up

I used this to replace a blown amp with an aftermarket Pioneer hu on a harley Road King.Well built sleek looking unit.Easy to install started adjustments on low and gradually turn up for best sound and wow, does this perform. Replaced a hertz marine unit with this with similar specs and there is no comparison.Loud, obnoxious clear bass and highs/mids. If your sitting on the fence, don't hesitate.
