P600X4 Punch 600-Watt 4-Channel Amplifier

It's been quite a while since I bought an amp. The industry has really changed, and for the good. More features/perfornace for less cost. I've mostly owned Alpine and Precision Power amps, and I tried to buy another PPI, but they were out of stock, and I took a look at Rockford. The prices were pretty good at this time so I took a chance. The P400x4 is compact and heavy. I was surprised at the quality of construction, really nicely done. Things like that can tell you a lot about a company. Anyway, the feature set is also quite good, and being able to double the wattage from 4 to 2 ohms is seriously impressive. And the bottom line of course is the sound. This amp is really nice sounding. I'm running a set of Pioneer components, and the amp drives them effortlessly. They don't have much low bass, so I won't comment on that, but the balance and quality of vocals, instruments and highs is really good for the money. Imaging and soundstage, it's all there. I'll be buying another amp next year for the subs, and it'll be a Rockford Fosgate. Edit April 29/16 I changed up my system as I upgraded the wimpy stock 6x9 speakers on the back deck of my Altima with Pioneer TS-D6902R. I'm now running 2 channels of the amp to the rear speakers, and the front comps get the other 2 channels. Wow. This amp is making my jaw drop running all speakers full range. Lots of tight bass from the 6.5 and 6x9's. Clear, clean, effortless and more volume than I can handle. You really can't go wrong with these Punch amps.

This is a great amplifier and I've had mine since 2018. You can tune it to the way you want and to prevent clipping it has a nice led indicator. I have Rockford Fosgate everything except my subwoofer amplifier and my front door speakers as I found something better for my application. I am using this to drive two cheap speakers on my rear deck and two JL C1 speakers that can perform at a high volume. My only dislike about this unit is between my aftermarket head unit and this amplifier I've found it simply can't produce enough volume before it starts clipping. I would've been happier at the time I bought this if I had gone with a more powerful Amp but for current me this suits me most fine. For most applications this will provide you with enough volume and quality that you need, unless you're trying to show off and it gets a little distorted when turned up too loud. This is a great Amp and once you set it up you'll never touch it again. I would recomend mounting it down as I used an 8 Guage wiring kit(could have gone with 4 Guage but this unit doesn't really need it) and you definitely don't want that to get pulled out. Would recomend for casual listening but not show boating.

Was debating between this and the 4 channel Power series. I am glad I went with this one because it matches my speakers perfectly. I am pushing four 6.5 inch Sony 162ES component speakers which have an RMS rating of 90 watts. The birth certificate of this amp is over 100 watts per channel at 4 ohms so they match perfectly. It my opinion RF amps are the best amps you can get. The comfort that comes with buying this brand, knowing it will last for years and years is worth the cost. I don't feel like dealing with a dead amp every 2-3 years. I am also pushing my subs with the RF Punch 1000. I am freaking rocking out. The best sounding, well rounded system I have ever heard.

Gr8 buy

I replaced an Alpine (100w x 4) class-D amp on my boat with this Rockford Fosgate (75w x 4) class A/B amp and it sounds much better . It's driving (4) Alpine 6 x 9 speakers, model 6912m. More than enough power. This amp gets just as loud as the 100w Alpine. I think both amps are plenty of power for the Infinity's. This amp was very easy to fine tune. Nice controls. Parametric Bass EQ let me pick the bass frequency I wanted to boost and then a separate gain control to adjust the bass level to just how I wanted it. Perfect Boom... but not too much to interfere with the rest of the music, but it's really there. Boom. All the harmonics that were missing with the class-D amp are back now. I listen to rock and occasionally rap/pop. This amp is perfect for that. Rock on Fosgate!

PUNCH p600.4 is a good amp, it produces a good amount of power and its clean sounding , high SQ. MY SPEC SHEET Claims 529 watts @ 4 ohms, thats right around 132 watts each channel@ 4 ohms. This amp has the c.l.e.a.n technology and it appears it does a good job cause the sound is clear at high volume, my ears give out before the clear music does. This amp is pushing 4 HERTZ door speakers and its loud, prolly hearing damage loud, but still clean and clear with no distortion. Of course i dont ride around with it playing full tilt but its fun to show off to stereo enthusiats.

What an awesome amp. I did not need it to push a sub so it was all I needed to make my Tundra loud! Had a problem with it and it quit working and the customer service took right care of me. Sent me a new one and it was an easy swap and now no more issues. Thanks for a great amp and a great buying experience

Got this in yesterday and to my surprise the birth sheet was 821 watts! Running 2 sets of alpine type r 6.5 components at 4 ohms, my soundstream 4.560 was louder at 4 ohms but the sound quality on this is way cleaner. It is 3 times the price but you get what you pay for! The set up was kind of confusing at first with the clean set up, but found out my radio does not distort even at max volume, after that it was easy. Very clean look and for being 1/2 the size of my other amp it weighs a lot more. Sounds just as good as my wife's jl 700/5 xd but a lot cheaper. After breaking this in i read more and turned the punch eq up that also works on the hpf if you read instructions, after turning this up 1/2 way i can turn my stereo up 1/2 way and it is loud! So if you purchase it before you think its not loud play with the settings before thinking something is wrong. Just bought the t1 6/9', and t1 component 6.5's to match. Update this review once thats done to see how they match up with this amp soundwise.

Excellent quality

Awesome deal (CDN 303$), I cannot beleive there was no hidden fee (no canada+quebec taxes, no duty fee). At this price it was a real bargain. The shipping was incredibly fast for only 5$ (about 2 or 3 days). This amp was a fun project to install and it deliver the RF promises.

Great seller and amplifier. It solved my white noise coming through my speakers.

Excellent sound great power wouldn't hesitate to buy again
