Yea this is the one!!

T-600 great amp powerful and delivered just like they said. Only problem for myself matching 6x9 or bigger I melted all voice coils. I want to buy most powerful RMS speakers 4 pairs and add T-1000/4.

Rockford Fosgate Power T600-4

Really good AMP for the money. Super clean sound. I have it hooked to 4 Infinity Kappa 6x9's and it is crystal clear and EAR BUSTING LOUD! A++ on this one. I'll rate this in the top 3 of the 25+ amps that I've owned over the past 30 years. YEP, I'm an old guy and still rockin'. Get this AMP you will not be disappointed.

Awesome amp

This is one of the best amps I have ever owned. Stands up to everything I can throw at it and never backs down. Great piece of equipment and puts out way more power than rated. Mine out out over 150 watts per channel at 4 ohms and over 250 watts at 2 ohms.

Best 4CH amp on the market

My amp came with a birthsheet stating 130wrms x 4 CH @ 4ohm. Which is awesome. Sounds clean and crisp with the RF T2 splits.

Great Amp from a Kicker Amp Fan

System this amp is servicing: A mustang car: Fronts 6.5 component set, Focal 165 KRX2, which are 2 ohm each side, rated at 100 w rms each side. Rears, Polk MM571, 2.7 ohms each, and are rated at 90 w rms.

Previous amps: Kicker IX500.4, Kicker ZX650.4. Kicker ZX650.4 is just as good as this amp, but it's 20 inches long. This RF T600-4 (just under 15 inches long, which is the reason for purchase) is a little bit stronger, sounds almost as good (Kicker has better noise filtering). Noise filtering is the weak point in this amp. It's not much engine noise, mind you, but it's there. Fortunately, the amp is too strong for my speakers, so I can almost, almost eliminate the noise but turning the gains down lower than the SMD-1 (great device by the way I purchased here at Sonic) calls for them to be at.

I have learned its best to get a too strong amp and you can always turn the gains down lower than they should be, rather than too weak of an amp, and turn gains up beyond where they should be. I also do NOT use any bass boost.

Overall, great amp, very pleased. My specs on this amp's birthsheet: 122 x 4 @4 ohms, 189 x 4@2 ohms, 379 x 2@4 ohms

I am happy.

I purchased this amp along with the rest of my gear at the same time Rockford Fosgate type-(T1652-S, R1653 and P1S4-10). The whole package in my 2011 Chevy Truck is CRYSTAL CLEAR. The Sub Bumps nice and tight. SOLID piece of Gear. GOOD Bang Power Clarity for my setup.

Insanely amazing Amp!

I stand behind Rockford Fosgate amps 100%. Flawless quality and build design. These amps take a beating. The birth sheet that came with this and the Power T1000-1bdCP were both rated 25% higher than the actual spec of the amp!!! Most manufacturers barely meet the advertised one. Buy this amp and don't hesitate to do so!

Great sound, plenty of power

I love this amp! I had a JL Audio 300/4 v.1 prior to buying this amp. Actually I had 2 JL's and they both went bad. Decided to get a Rockford and never have regretted it. Very dependable, doesn't overheat when I drive it really hard. I have CDT speakers and they demand watts and the Rockford 600-4 delivers. Noticed that the Rockford sounded so much better than the JL. I cannot understand it, but it is what it is. Buy Rockford, you will never regret it. Oh, by the way, I've had the 600-4 for a year and half and it just keeps crankin out the music, no problems. I like the phillips screws for wire connections. You'd be crazy to buy anything else!

Great Amp!!!

I switched from my Alpine 4 channel to this bad boy. This amp is the best component amp you can buy. Mine came rated at over 140 watts per channel at 4 Ohms. Had to turn the gain down to not blow my speakers. Amazing amp, worth every penny. Trust me, you will not be disappointed.

Great Product

This amp is a work horse in a small chassis would recommend to anyone looking to get that edge in sound quality and power..... Great buy

Amazing Amp!

This amp is the best component amp you can buy. Mine came rated at over 150 watts per channel at 4 Ohms. It quickly blew one of my Rockford Power 6x9's! Rockford is gonna have to come up with some more powerful speakers or else I'm liable to blow all my components lol. Amazing amp, worth every penny. Trust me, you will not be disappointed.

BA amp

Got this T600-4 on a set of T2 6.5"s and some Boston Acoustics 6.5's but about to replace the boston's with a set of T3652-S. This amp definitely makes some power.

compact

This is a sweet and small amp (for the real output). Well over 100 watts at 12 volts, I tested it (my birth sheet says 131 at 14.4 volts) not to many manufacturers can say that they even have one four channel that can do that, Rockford has a few and as always the quality you have come to expect from Fosgate. this thing will surprise you with its weight. The value is there, the performance is there, if you are thinking about stepping up to a real 4 ch. then do not overlook this one.

Rockford Fosgate T600-4

This amp is freaking awsome! The one I have, the birth sheet has it rated at 227 x 4 @ 2 Ohms thats 127 watts over what it is rated, wow. This amp is powering a set of T2652-s 6.5" components and 1 additional set of T2T-s tweeters, along with 2 - T1693 6 x 9's. This is an excellent buy for anyone.

very good 4 channel amp

i listen music with this amp in 3 systems:
1. alpine 305 headunite,rockford fosgate t1652s component,rockford fosgate t600.4 amp,alpine m1005 monoblock and alpine 12" type r subwoofer.
2.alpine 9835 headunite,JBL p6563 component,rockford fosgate t600.4 amp,soundstream rub1.1000 monoblock,JL audio 12W3V3 subwoofer.
3.Alpine 9887 headunite,alpine spx-17pro component,rockford fosgate t600.4 amp,rockford fosgate T1000 monoblock,alpine swx-1243d subwoofer.
i can say that this amplifier suitable for all of component speaker and best for SQ systems.

Awesome

Out of the box the spec sheet included said this amp was rated at 133 watts RMS at 4 ohms, tested in Dec of 2010. Awesome... more power just like that! Get some good speakers that can handle the juice. I have Rockford Fosgate T2652-S components in my front doors and I bridged the rear channel to power my 10" JL Audio sub in the trunk. I couldn't be happier with how great everything sounds. Nice, clean stable power is what you get with this amp. I also got the Punch remote hooked up to this amp so I can make adjustments from the front seat. The adjustments this remote makes is more like a fine tuning. This amp feels heavy and actually smaller than I imagined for getting so much power out of it. Would def recommend.

Great amp for speakers.

The brand alone is worth buying, Rockford quality with amps is impressive.
Ab class goes effectively with the T3s pairs I have running, sounds crisp and loud!

Rockford Fosgate

Great amp! The sound (loudness and quality) is great! All I could have expected. Great over the phone technical installation support from the supplier!

Clean Power-Efficient

The T600 performs solid. Runs cool. Reliable clean power. Trusted brand.

Awesome Amp

As with all of the Rockford Power line this amp is awesome. The power output is quite amazing. The birth sheet says that it is rated at about 1000 amps at 14.4v and I believe it. I haven't pushed it very far. Using it for some Rockford 6.5's and 6x9's. Good stuff.

Nice little powerful amp

Compact, clean and powerful amplifier. I used it to drive some old 6.5 MB Quarts and a twelve inch sub in my recently back on the road 67 Buick Riviera. The car had been off the road for many years and I had stolen the four channel Mcintosh out of the Buick while it was sitting for another car so I needed a replacement. I am partial to the Mcintosh amps and have them in several cars but I was not disappointed by the power of this RF.

T600-4

sonic electronix is my go to for all my car audio needs.
they ship fast items arrive fast and the vip points keep me coming back

I love Rockford fosgate!

Been using Rockford fosgate since I was 16 and still til this day can never get enough of first how good their amps look but also their sound quality! Won’t find many others like their amplifiers!

It's Rockford Fosgate!

There's nothing to dislike about this amp. I have been a RF fan since the late 90's to the early 2000's. Every power series amp is nothing but pure power with no compromise in quality or manufacturing. You'll be more than pleased with your purchase when it comes to buying one. Whether you're using it for your highs or subs, there's always lots of power at your disposal. Just buy one and see for yourself, thank me later!
