Best Affordable CLASS D 5 CHANNEL AMP for the Money

This amplifier and brand is the best kept secret. I knew of this brand since the late 80's early 90. Precision power was been around for a very long time. Precision Power have been on a bit of hiatus over the years. So the younger kid's might not know of this brand when it comes to car amps.This company has a reputation for quality products at the best prices. They were consider a premiere quality brand back then and they seem to be making a comeback on the market. I bought this amp before the Christmas Holidays, I knew, what I was getting before the purchase. I thought it was a price error. But No Folks!!, This is the Real Deal. For this price point; This is a real steal.... Your getting more than your monies worth. It's POWERFUL, CLEAN, SOLID AND COMPACT. It will fit in a multitude of places in your vehicle. I highly recommend this amp. If, you want quality at a low price look no further. The specification speaks for itself!

Great Amp!

This amp was an awesome buy! Precision Power has been around for quite a long time, so I knew their reputation before buying this amp (always made good stuff).
I put this in my son's car to power his whole system, and the mids and highs are crystal clear along with powerful bass. The remote bass control is good for turning the bass down quickly when the blue light specials are enforcing sound ordinance laws. Who wants a ticket for listening to a little bass ((((( right?

If you're looking for a one amp solution that's clear and powerful, then this is it and the price couldn't be beat. Thanks SE

Great price with plenty of power

There are other brands with the same board that this amp uses from NVX 900.5 and polks pa d5000.5, but this PPI have the lowest price and more watts per channel especially the sub channel. I was worried that this amp might cause hissing noise, but nope. Everything sound nice and clear. I have a 4 volt pre out from my pioneer x4500bt and I set it at 3/4 volume which is 30. My gains are at half for all channels. No distortion.

Fantastic amp

Couldn't be happier with this amp, solid construction, looks great, sounds absolutely amazing, but the best part us the power, I run 6.5 components up front, 6.5 coaxial in the rear and a dual voice coil single 12 inch sub which is paralleled down to 2 ohms. The system truly pounds! I could not belive the power and sound quality.

Good Amp For The Pice

Amp Produces Good Clean Powerful Sound at a good price. Rumor has it that some of the cheaper amps use the same circuit board as the more expensive amps, but then again everything is made in asia now days. Anyway if you are on a budget like me, this is the best bang for the buck. Doesn't produce earth shattering bass, but produces good balanced sound across all frequencies.

AWESOME POWER FOR THE PRICE!

I bought this amp at first because of 2 main reasons,1 im an old school basshead and owned ppi amps in the early and late 90s and rememeber the good clean power they had in there amps not to mention there reliability,2 I honestly was in need of an amp with a price tag under 250 to put a nice clean sounding system in my work truck which im in 10 -12 hours a day... even worktrucks need a little bass and sq...lol So I ended up buying this amp ,an re audio,10 in sub,and 2 pairs of pioneer 6 3/4 D series coaxials all here at sonic for under 500 bills!....thx sonic:) well i must say with all this an extra set of pioneer tweets, my custom 1.9 cu ft ported box,all ofc1/0 amp kit and big 3 upgrade ,This amp POWERS it all and SOUNDS CLEAN !! I love the small footprint and was shocked how much sound came from this small looking amplifier,this is my 1st time of owning a class D amp so i was a little weary about running my sub at 2 ohms, but not only does it sound clean but it doesnt get super hot either!,I built a little amp rack for it and mounted it under the rear left 6 3/4 speaker on the panel above the rear seat and even after playing it for over 5 , 6 hours straight this amp got warm but never really hot, when it got warm i just opened the rear window above it and it cooled right back down again, never saw it go into protection mode yet:) I really liked the 0 guage adapters it came with too, even though I had to trim my 1/0 wire to get it to fit I was happy I diddnt have to use a distribution block for power or ground,overall I love this amp,for the power and price I got it for im gonna give it 3 stars on durability cause I have had it for a few months now and cant rate durability just yet,but so far im very impressed!

Nice Amp for the Money

In general, I am happy with this amplifier, and I don't think you can do any better at this price. I wasn't sure about it after initially hooking it up, but after using it for a week and fine tuning, I think it is well worth the money. It is hooked up to JBL front components and a JBL subwoofer right now, so I am not using the rear channels yet, but may add rear fill speakers in the future, which is why I got the 5 channel. You will not be disappointed with this amp. Also, I love how easy a 5 channel amp is to install instead of multiple amp setups (No distribution blocks!)

Pros:
Price, features (Subsonic filter, LPF, HPF, Bass knob, etc.), looks nice, sounds great, doesn't run hot at all (just barely gets warm so far, and I am running at 2 ohms)

Cons:
Not CEA-2006 Compliant, but it seems to provide enough power

Best 5 Channel Amp for the price.

I spent a few months researching, asking questions to dozens of people who were "experts" in car audio online and elsewhere about Speakers, Amps, etc.. Most of what I had initially had in mind changed after their input. One resounding recommendation was the buy the PPI Brand amplifier. Low or Medium high budget.. everyone liked the quality.

I originally was going to buy a PPI 900.4.. but at the last minute found the PPI 900.5. In my car (350Z) I have four 6.5" speakers.. and the front 6.5" speakers are in the doors low.. and the tweeters are in the panels by the windows (components factory).

So I needed something to power 4 6.5" speakers with 1" tweeters (aftermarket) that ran 70-80watt RMS per speaker and MY choice on the Sub was a JL 10" sub that ran at 300Watts RMS.

The PPI 900.5 was about as close as you could get to these needs (but don't be afraid to buy MORE amp than your speakers require (you set the gains remember).

I was hesitant about a "Class D" amplifier to begin with.. having always used Class A/B.. but I went with about a dozen recommendations and bought it.

I've since installed and wired the whole car myself.. and am 10 times over more impressed than I ever thought I would be with this setup -- and the Amp drives it all.

A cheap/bad amp gives unclean power and you hear that.

I have supreme Sound Quality.. incredibly SPL .. with Clean Mids, Bright (but not overly bright) highs.. and the 10" Sub is in a Sealed custom box for the vehicle at .66 Cubic Ft,.. and this amp drives it very, very well. It's tight, quick response bass -- but if I'm watching a movie on my DDX470's DVD player, it's like being in a Movie theater with the rumbling bass etc.

Bottom line -- Don't hesitate if this amp meets your power requirements.

Nice Class D amp, good value, rated power

After a couple weeks of research I decided to pull the trigger on the PPI 900.5 amp. I am using this amp to power JL Audio C2-650 components in the front, C2-650x coaxials in the back and a 12" Infinity Kappa 120.9W sub in a 1.0 cu/ft sealed enclsure. The speakers are 60 Watts RMS and the subwoofer is up to 350 Watts RMS, which makes this a nice amplifier to power this setup. At first I was a little skeptical about going with a PPI amp as opposed to an Alpine, JBL or Kicker amp, but I trusted all of the reviews I read online and I am glad that I did. The PPI amp is at least $100-$200 cheaper than comparable amps from the brands I mentioned and even though I can't compare this amp directly to any of the other amps, I can say with confidence that this amp is well made and does rated power. My only issue with this amp is that the frequencies on the crossovers aren't identified (for example, 80 Hz isn't labeled) so this makes it difficult to tune. That being said, at this price point I am willing to make that concession.

Nice amp for the price

Pros: This amp run nice and clean from what I could see on my scope and by the sound it puts out. The power is great and the sub ch pushes my 600 watt rms sub real good. The amp stays cool but I have a few fans helping it just in case.

Cons: What I don't like was the screws for power, they are a bit hard to tighten because the case gets in the way. I had to find the right size to get in and be sure not to strip the heads of the screws. Also not enough number markings on the settings. I had a hard time trying to set the high pass at 80-90 hz because the lack of markings on the settings. Not hard to figure out but more numbers stamped on it would have been nice. And the last part was the mounting holes to hold it down. You have to use a screw with a small head to fit in the mounting hole, wood screws wont work they are way to wide.

GREAT price Great amp.

Just installed it puts out all the highs and lows you will need. I'm running 4 pioneer speakers and a pioneer 10" sub (down fire). Sounds great. Black Label Society never sounded better. Recommend this amp highly.

Quality 5 channel amp for budget price

This amp does pretty well for price and size. it does get hot,I have it under the false floor in the boot of my a4 avant -not vented yet it's driving two sets of morel virtus 6.5 and a nvx 15" at 2ohm sealed box . I have run PPI amps since the mid 90's Skipping many of the not good years of ppi
This was a fall back amp while my other amp is being returned for being partially DOA on arrival- massive audio nx5
I had this running for a 4hr road trip in phx AZ an it didn't shut down do to heat yet
Definitely recommend this amp ,solid built. Only gripes I have are the speaker terminals top screws under a over hang and 1/0 to 4 reducer don't fit in the amp terminal very well

A bit of buyers remorse--A lot actually... :(

Alright so this is brutal and honest from a man from the old school.

This amp was ok when I got it... Heard it in another friends car and honestly I was immediately impressed. To be honest; when you get a good batch of one of these; they are awesome... But don't be fooled... Epsilon who also owns Soundstream, Crunch, and Power Acoustik is behind this amp... So QC and build quality are hit and miss... Gone are the days of PPI meaning a 15 year life gem... That rant being said, this amp lives in my wife's Subaru Forester under the trunk floor. It powers a CDT Audio 3 way set, a set of CDT Audio high def coaxes and a Sundown Audio SD2-8 subwoofer. Since new there has been a whine (not a rise and fall like an alternator) but a small whine that gets covered around 7 out of 40 on the Pioneer AVH-X3500BHS deck... Now before you start yelling Pico Fuses; that has been checked... I simply got a bad one... By the time all my troubleshooting was exhausted my warranty had lapsed by 4 months... So I am out of luck...

The left front channel is staticy and garbled upon first turn on until around 9 of 40 volume on the deck and then straightens out. I remounted all the crossovers and I have been installing since 1991 so please don't think I'm a noob... I thought hey maybe the factory wiring is bad... Nope, reran all new wiring (I had used 9 conductor speed wire prior--which I bought here) So long story short don't second guess yourself... I got a bad unit... Even Epsilon agrees; but my warranty is up... Never again...

I am beyond frustrated... If you get a good one; you will be happy; if not you will have your gig harshed and have your wife angry at you like I do... Sad part is... I spent around 1800.00 on her system... I read reviews detailing how this is the same basic amp as a Hertz HCP-5 for far less coin... I auditioned one... I bought in... I got burned... :(

Good sound but quirky

The "second" one worked much better than the first. The sound is really tight and clear with tons of power. The crossovers and external sub volume work well. However, this amp is power hungry. You will need a strong 12v on/off signal and most importantly a good 14+ volt altetnator. It really doesnt get enough juice from a 12v battery. Expect heat like most amps with this power. Got this and the 900.4 and things really rock.

AWESOME LI!TTLE POWERHOUSE

I purchased this amp on the strength of the PRECISION POWER name. I'm an old school stereo guy that had competition systems worth thousands. I always went for the best. Being a home owner and a grandpa my priorities have changed so when i saw the name and price I jumped all over it. This amp out performs my JL Audio XD700/5 by far. If you want the best bang for your BUCK get this amp.

Great Amp

I had 2 PPI amps back in the late 90's and early 2000, they were one of the best back then and still are. I put the 900.5 in my Avalanche with 4 Kicker 6.5 speakers and two kicker 43c104 10's and it handles it great. It's been in for 2 weeks now pounding it out, the front and rear gains are just cracked and the sub out put is a little past half way so it has plenty of clean power. If your looking at this amp just get it you'll like it.

PPI is back

Stunned by the sound and power of this amp. I have 2 PPI Art series amps (A600 and A404) but needed something smaller. This amp more than fit the bill. Bench test shows output right on par and as advertised. There was a time supposedly that PPI feel behind on quality but this amp dose not show any signs of that what so ever. Runs cool and a tone of headroom.
