Precision Power PPI i520.4

We’re in a time where small is popular. Reduced, more economical vehicles are more and more desirable. But that doesn’t mean you have to sacrifice massive power for your audio system. The Precision Power iON amplifiers pack vast amounts of power into small chassis thanks to marvelously efficient full-range Class-D topology and SMT technology.

Complimented with every possible preamp adjustment, the iON series leaves nothing to be desired. This series includes a four-channel model with built-in Bluetooth (i520.4B) to stream audio from any smartphone app to the vehicle’s speakers. Seamlessly pair your smartphone or other enabled smart devices for continuous audio playback through speakers, great for when you can’t have or change a source unit in a vehicle. This is a noteworthy addition to off-road trucks, motorcycles, or personal watercraft overlooking a music source unit. The Bluetooth model also comes with a pass-through cable to connect additional amplifiers to create a daisy chain configuration.

Great!!

This is a powerful amp. I am running 4 of the 7" alpine marine speakers with this amp. Wow!! I have room for 4 more speakers on this amp. Very pleased. I highly recommend.

Precision Power PPI i520.4 - a stealth addition to my reportoire

Been dying to amplify my 4 coaxials, 2 Kappas in the front and 2 MB Quarts in the rear. This thing delivers, and packs a wallop at such a small footprint. I can see others mounting this is other stealth spots like under the driver seat or even under a truck bench. And it puts out the wattage! Trust me, quality PPI construction and performance at an absolute steal of a price!

Good Amp

The amp works well. I mounted it under my passenger seat. The vehicle was a 2004 corolla. The amp was so small, it very easily fit under the passenger seat. Installation was a breeze and it powers my kicker speakers very well. The one con I found about the product is the ground and power terminals on the amp are stacked on top of each other. Normally those terminals are side by side. I ran 4 gauge power and ground to the amp. The gauge was so large, I could not screw the ground wire screw down far enough to fit in the power wire above the screw. I had to trim down the gauge of the ground wire and power to get them to fit into the terminals. You will need to trim 4 gauge wire or go with 8 gauge wire.

Great sounding amp with lots pf power.

Great sounding small amp with lots of power. I used his amp along with a new set of components and rear speakers and this little amp rocks. With its small size was super easy to do a clean install and easily hide it

GOOD

Owned it for seven months now, it plenty of power and no noise, clean sounding mids and highs lasts long, runs warm-borderline hot on 95 degree summer days but on normal weather 50-80 degrees, it runs real cool. What have i used that i can compare it to? JL audio 60 x 4 A/B channel amp, no difference in sound quality at all, but this ppi amp offers more power with better efficiency. Definitely way better then my friend's hifonics zues/gladiator 100 rms X 4 channels in terms of sound and raw power. Only bad thing i can knock on it is that its not Active capable, pretty much an amp with globs of power and minimal crossover functions.

Awesome little amp.

This amp can be hidden anywhere, so it makes installation a breeze. I had always been a PPI user, and wanted to see if PPI still produces good products.

Even though I am currently only using it for my component set (MB Quart OSC213), it sounds great with no overheating for a chassis this small. I still have to connect my Rockford 10" to it, but from what I have heard from it so far, i am sure i will not be let down.

Great little amp for the money.

This amp is a great value. I'm running a front soundstage in my car from this little guy, and thus far it's been great. I can't speak to its crossover capabilities since my DSP is handeling that end, but the power is sufficient for my 7" drivers and 2" tweets.

Great product!

People will underestimate the power of this amp, I hook it up to 4 infinity kappa at 2.7ohm and barley touch the gain, my door speaker are screaming at me.

Great amp

A great little amp, used 8ga cable for the power and ground. Its powering 1 Polk 5x7 and 1 Alpine tweeter for a 2 ohm load on each channel.
Couldn't be happier!
