Polk Audio PA D5000.5 900W RMS, 5-Channel Class D PA Series Car Amplifier (PAD5000.5),100 Watts x4; 400 Watts x1

It's running 6 CT Sounds speakers in my GMC Sierra and an 8" sub. I have an LC2I Pro and gains set with osc. This sucker is clear - and it's pretty loud. As loud as I'd ever need in my new truck anyway. The base model 2020 Sierra came with terrible audio, it was gutted right away. I tucked this amp behind the rear seat and ran 4 gauge to it. It's happy, not a crazy power draw - and all the speakers are loud and clear. If I recall I have a 600RMS 8" CT Sounds sub and I think it's at 4 ohm final load, I forgot to check. While this bass output won't satisfy bass heads, it is excellent as an "OEM+" kind of build where I want sound quality and tight bass over SPL. And this really delivers some clean, clear bass. 4 ohm on the sub channel isn't much, but 2 or below is perfect and more than I could need in a truck. Very happy I went with this over a taramps 4ch or other $100 amp.

I own a custom car shop and I'm an audiophile who's built a fair amount of high end systems and this amp has been great in my daily truck. I'm running 2 Kicker twelves at 2 ohms and Polk MM series 6.5's with active cross overs and remote MM series tweeters. It sounds great and I have had no thermal issues even in the Arizona summer heat. I'm about to purchase another one for another system that I'm building.

Under $200 to power the whole vehicle. I have it pushing 4 infinity kappa 6x9s and a kappa 10" quite well. Easy to setup and adjust the crossovers. ALOT of wires but so far so good and sounds great.

So I had the same version of this amp but a 4 channel in my boat prior for last 12 years. That boat even took on water and had a water line across the amp from 10 year ago, it still works amazing! I bought another boat and decided to buy a new one just a 5 channel version. It lasted 1 day in the boat, never made it in the water, should not have got wet as this one was inside a center console, my other boat was visible from the deck and gets wet with every wash. Maybe I got a bad unit but I replaced it with a Rockford unit for 4x more money. I'm guessing just humidity killed it inside the console. Obviously it's going back to Amazon and if it makes it back to the MFG then hopefully they are able to see the issue and improve upon it. Sad.

Great bang for the buck. I had and installed many stereos and amps and this little guy packs a punch. Your highs and mids will sound amazing. There isn't enough juice on the sub channel for high volumes pushing a single 10" but at low-medium volume, it gives off a perfect balance.Was trying to find a amp that fit in my factory amp location on a 2001 wj jeep Grand Cherokee. I'm running a after market deck with a front, rear, and sub channel preouts to the amp, ran fresh speaker wire to after market 2" dash, 6x9 doors, and 6.5 rear doors completely replacing the factory infinity system and I couldn't be happier... Well, if the sub channel had more power of course. But, for the price, it's great

I bought this amp mainly to to its ability to run a 1 Ohm load subwoofer, which is installed in my BOSE equipped system. I ripped all the BOSE stuff out but had to keep the subwoofer. I am running a DEH-80PRS HU and using this amplifier to power a Hertz HSK 165 component speaker setup and the said subwoofer. This amp fits nicely into the available small space, is easy to connect (all connectors side mounted), has a very good manual to allow good setup and mounts easily. It is not flash, has an understated look. Since it is a class D amp (not identical to digital amp) it rarely gets too hot and is well suited to run in confined space with low to non ventilation (frunk of a Porsche).In my setup the amplifier exceeded my expectations and at its price point outclassed several high $ amps, which were available for me to choose from. However, non of the competitors I compared it to could run 1 Ohm sub.In the Network mode setup of the HU the sound is crisp, well defined and the bass tout, not bloated or boomy. The Cabriolet is a noisy car with or without top down, and requires all the power this amp can provide. I have never managed to clip this amp, even at very loud volumes, with the speakers being the limiting components.In conclusion I am very happy with this amplifier and would buy it again without any hesitation. In fact I am considering a spare one, just in case.

Installed this in my 2014 ram 1500 express today, its my first 5 channel amp and first amp install. Its pushing a set of infinity kappa 693.9i 6x9's up front and lower end kicker ds693 6x9's in the back, along with a 8" bazooka for my sub. The HU is a couple year old pioneer avic-130bt.Sounds great so far,nice & clean, no alt noise or hum just need a little more time to tune it... I've had the same off brand ( lower end ) 4 channel and sub amp for the last few years or so and wanted to eliminate the two amp set up in my new truck.The first thing i noticed is much better low end frequency response and better overall imaging. I thought it might have a bit more headroom on the sub channel but again probably just need more time with it. I did notice it get pretty warm after being on for about a hour or so. I used 4 ga wire and took my time with the install.Overall seems like a well made amp that should last for a wile, ill go 4 stars for now and update in a couple weeks.Here we are a few weeks later....great little amp, has not shut down or gone into protect mode after a good amount of pushing it. In fact i added another 8" bazooka tube ( running 2 now ). I got things dialed in and it sounds really good at all volumes. Very happy with this amp so i went ahead and gave it 5 stars!
