Polk Audio PA D5000.5 (PAD5000.5)

Great value for money.

Pros: Great looking amplifier, and it has very clean sound with good specifications. Nice and compact, and fits under front seats very easily. Great value for money.

Cons: It doesn't have bass boost feature.

Great all in one amp

This amp is fantastic, power is true as advertised and the sub section is stable to 1 ohm. It's really tiny and fits perfectly under the seat of my 2013 Mazda CX-5. I have it running off an audiocontrol LC6i and powering my OEM speakers for now and a single 12" MB Quart PS3 sub at 4 ohms. I get a clean, noise free signal from my factory head unit. Everything on the amp seems solid, and it's marine certified so you can use it in a jeep or a boat as well. It is capable of running all 5 channels off a single pair of RCA's if needed which makes installation very flexible. The included bass boost knob is great and there is a green light on it that is on when the amp is on. Overall I'm very happy with my purchase and would definitely buy this amp again.

Good Value 5 - Channel Amplifier

Pros:
- High Efficiency: doesn't draw a lot of current, runs cool
- Compact design: makes installation easy
- Sub section very powerful: drives two JL 10s easily
- Versatile inputs: one set of preamp inputs can drive all 5 channels
- Superb Sound Quality

Cons:
- Subsonic Filter Non-defeat able
- Gain Control a little too sensitive
- Not Gold Plated Input/Output Terminals
- Crossover Controls dont have frequency markings
- No High Level Inputs (not a con for me but some might need it for OEM integration)

Great sound

I just recently brought this Polk Audio amp. It is fantastic. I installed it in my boat and it performs beyond expectations. Wish I would have bought one years ago. Easy to install and takes up very little space.

Small Amp with lots of power!

I got this as a gift to replace another 5ch amp not worth mentioning (CEA rated amps are really worth getting). Enough power to run 2 sets of Polk db6501 components and 2 10" Polk MM subs in a 1.2ci sealed box. Just make sure to tune your amp and you'll get loud clean distortion free music out of this little thing. I would highly recommend this if you're in the market for a 5ch amp.

great amp

works great and paired with polk speakers it makes them pound hard the only thing the sub control dont seam like it really changes it much other than that it works great

Great amp, clean sound, compact

In Toyota king cab pickup, mated to NVX door and rear speakers and Kicker loaded 10" (dual 2 ohm driver) sub that fits nicely behind driver. Once frequency crossovers were properly tuned and levels adjusted--wow! Great sound--Rock, funk, jazz (horns, cymbals, real drums, etc). Tight punchy bass, nice ringing highs with low distortion. I rewired the sub from 4 to 1 ohm to take full advantage of the amp, and limited the voltage to ensure my kids don't blow the speaker!

Instruction manual is weak--needs better section on proper amp setup. When you plug in the Subwoofer level adjust, you need to turn it up to 50% or so to begin to hear anything. Or, first leave it unplugged from the amp, set your max levels, then plug it in. If the adjuster is left turned all the way down (as mine came) you'll get NO SOUND out of the subwoofer channel. Neither the Polk nor the SonicE tech's knew to do this during our "debug" sessions! Silly, in hindsight. 3 stars for durability only because I haven't had it long enough to know.

Excellent choise

Quality crystal clear sound
Great base sound but and even better sound from the
Super tweeters
I love it and if you buy it you will love it too.

Best 5 channel ever owned

Absolutely as powerful as it states. I am using Focal components with this unit and a Memphis M3 12 at 2ohms. I am also using a capacitor and have nondoubt that this single all in one amp is top notch quality fairly small packge. Only hassle was mounting it. Clumsy design for screws. I ended up using 2.5 inch wood screws tonreach through corner mounts. Very happy...i have had other 5 channels before and had many issues...first time I've been happy with an all in one unit!

Good value

First time trying Polk audio for my car/truck. Very happy so far. Small in size but sounds great and has plenty of power for my four component speakers and sub. Can't give 5 stars on durability yet but very pleased on everything else.
