great buy!

This is a great little amp that puts down serious power. i currently have it powering a pair of alpine type R tweeters and another pair of alpine type S tweeters. the amps puts out so much power with gain set at 1/4 that the type s tweeters (100 rms rated) started to sizzle and almost popped while playing loud for just about 5 min. the amp does get warm after about 15 min of really loud music but never really gets to the point of burning your hand even after an hour of constant pounding. highly recommended amp.

Wow what a great amplifier! I have the PN4.520D Bi-amping a set of Sony XSGS1720S 6.5" Component speakers. This amp is very small for the power it puts out. very powerful. It is replacing a vega 500.4. The PN4.520D is by far more powerful and cleaner. The crossover is the only weakness of this power house.

Amazing !!!

purchased and installed 2 sets of MB Quart OSC213, a pair of RE Audio REX8D4, a Soundstream PN2.350D (for 8"s) and PN4.320D (for mids & tweets) controled by a Kenwood KDCBT558U. 8"s are in minimal enclosures(sealed) . this system is in a 2005 Ford f-250 Super Duty Crew Cab. Incredible sound. couldn't believe my ears. WOW!! the REX8D4's feel and sound like more expensive 10"s. i HIGHLY recommend ALL these components,and will use them again on future installs...

Awesome Amp

I ordered this to replace a kenwood 400w 4ch amp that I had in my car. My primary reason was for the size cause I knew it would fit under the seat. I have previous experience with Soundstream and know that they put out an amazing product. In fact this amp is pushing SoundStream Tarantula speakers up front in my car that are 5.25" and those replaced the 6.75" alpine type s speakers I had and I always felt those were pathetic.

For the power output and 4 channels this amp can't be beat.

so far, so good

Only had this product for a month and installed for a week. That being said, it fits nicely inside the fairing of my Road Glide. I have it pushing 2 5x7 hog tunes speakers in the dash and 2 6x9 polk audio db series marine grade speakers in the saddle bag lids. The sound is very clean and vivid. Distortion is non existent and I couldn't be happier. It's running off of an aquatic av head unit with 2v rca outputs. I have a bit of adjustments to do on the gains but overall it seems like a good unit. The only downside is some tolorable interference with fm reception as expected with a class d amp.

great amp

Have this little gem hooked up in my probox on my can am maverick. It really makes those 6.5 sing. Everyone is amazed how much sound comes out of those 4 speakers.

Big punch in small form

This thing puts out twice the power of my stock head unit. Installed in my trunk, almost invisible due to the small footprint. Would recommend if you're on a tight budget but still want good bang for ur buck....

Great little amp, big in power

I "downsized" from a larger four channel MBQuart amp to go class D and fit two amps where one was before, while almost doubling my wattage. This little amp fit the bill perfectly. Easy install and setup, since I am using the head unit crossover.

I'm feeding a set of JBL P660c components up front and coaxes in the rear. This combo rocks. I don't think I've maxed out either the components or the amp yet. Super loud and clean. Also paired with a Soundstream PN650.1 sub amp driving a sub. The two amps are identical in size and appearance and look great mounted together.

Overall very happy with this kind of power and sound quality in such a small package. Highly recommended.

Cheap is cheap

Super fast shipping but 1 channel went out in 2 days. It's not worth the cost of shipping twice to replace

Tiny powerhouse

It's a stout amplifier with good output. The only negative I can conceive is the idea that the ground and power are stacked on top of each other. Make sure the power/ground is hooked up first before plugging the amp back into the battery or else ur going to have a nice spark show.

Even though the crossover is fixed, with an external equalizer alleviates any lack/excess of output.

Clean power, small footprint, solid materials. I give this amp a b+. I truly believe the power/ground connection was an over sight. It's not a good idea to stack the inputs.
