Plenty of clean power and excellent internal crossovers. Still working perfectly after over 9 years

None

This amp has no equal. I am bi-amping a pair of Focal 165-K2P's and the sound is simply superb. Focal insisted their crossover were the best solution but they never heard them played through 24 db/octave active crossovers.

Clean sound.

This review is for the ZX450, the predecessor of the ZX475. I'm using to power Canton separates and Pioneer 6x9s and the sound is very very clean! I highly recommend it.

clearity, power,great looks, cool blue lights

needed a dry cell battery to run the thing in a civic. killed the battery and alternator in one night of cruising

i was at an estate sale when i came across a pair of amps a pg 600ti 2 ch. and a 475ti 4 ch. i got the pair for 250. People didnt know what they had. Anyways at the time bieng i have just the 4 channel running 4 pioneer 220 watt 3 way 6x9s on the front channel and a pair of jl audio 12s on the rear channel. By far this is the best one amp system i have had to date.

everything, it is so flexible with the settings, its like sitting in a symphany hall if your into that thing.

It looks too nice, might get jacked by some jelous Home-0

as soon as i connected the power cable to the battery and hit the egnition at about 10 Pm after working all day i saw the back of my Blazer turn a crazy blue color. My speakers turned on and all i can say is Deeeammm. i drove for 2 hours with my baby blasting at the end i went to touch it and it was barely warm. I recomend this PG product to anybody. the new 600.4 ti just came out which is the replacement for what i have and i say if you have the bling bling then go get this amp. you wont be dissatisfied

POWER- Clean Power- which is very underrated at 75 by 4- extremely underrated.

It runs a bit hot in the trunk and shuts down from time to time. (I live in 100+ degree heat) I reccomend placing in the car or on the back of a rear seat that folds down to give it air. I did and never have a problem.

This amp rocks. I run my entire system on it! Talk about simple. I have Kicker RS6 components up front (6.5 mid, 1.5 tweet) MB Quart two way 6 by 9 in rear and a 12" enclosed Image Dynamics sub in the truck. The power is amazing. The sound is crystal clear. My friend at M & M wins competitions with his and he uses it to run his whole system as well.

Great looks, better X/o reliability than zx450 , controlls make more sense than previous models. Good power

Even with amp at minimum gain amp seems to shut off with decks over 4 volts.Seems to have reliability problems when mounted to sub boxes.

Sound is clear and detailed with good dynamics.When using an Eclipse 5506 with both amp gains at minimum and front and rear crossovers set to hipass,(a zx 600ti drives the subs and doesnot have a problem except on very hot days above 75 degrees) the amp shuts down above volume 65. I have also seen problems with the fans thermistor(used to turn fan on and off) busting. The thermistor can be bypassed if the amp is in the trunk of car but you may hear fan noises if its in the interior.

Clean, Powerful, runs cool.

I'd have to be smoking something pretty nasty and not sharing.

I got this amp and when I first got into the car I loved it. I had this amp presssed up against the sub woofer box leaving it less then one inch of breathing room. I was worried that the amp would over heat, especially since it was the summer. That summer it hit in the 100's degs and I played the music loud for very extended periods of time. I checked the amp, and it was kinda hot, but you could tell it wasn't even breaking a sweat. That thing held on with no problems at all.
It kept asking for more abuse. On nomal temp days, the amp runs warm to the touch. If anything I think my ears are going to give before my amp.
This is certainly a rock soild amp, the sound comming from is very nice.
PG did again, they made a winner 4 channel.
whether you want to compete or just have a really nice sounding as well as cosmetically appealing amp, this is the amp to get.
PG rocks!

Good power output, CLEAN sound

current hungry, but expected from a competition line amp.

This Amp will only shut down in EXTREME tremps. The guy who says his shuts off all the time is wrong and spreading lies. He said he paid $250 for this amp well all I have to say is "You get what you pay"
His phoenix amp is probably busted when he bought it or it's a fake.

I'm had it for nearly 3 years now and the warranty is going to be up pretty soon, but I've got no worries.
This amp has not had any problems to this date and shows no sign that will in the future. Phoenix amps rock!
This amp is a rock and definately worth the money.
