Rockford Fosgate performance in a rugged package – the Prime Series R600X5 5-channel amp can drive 4 speakers with 50 watts RMS each, while powering a subwoofer with up to 300 watts RMS. Not worried about your rear speakers? You can bridge the amp to 2-channel mode to drive a pair of high-performance components with 150 watts RMS each, while still sending that 300 watts to a sub. You can use the high- and low-pass filters and Rockford Fosgate's famous Punch boost to get maximum performance from your speakers and sub. And speaker-level inputs let you hook this amp up to almost any system, even a factory stereo.
The R600X5's heavy cast-aluminum chassis efficiently draws damaging heat away from its internal components, ensuring reliable, long-term play. The amp's built-in sensors keep track of the output current and power supply temperature, ensuring that plunging impedances (they change constantly during play) or even a short circuit won't hurt anything. Your driver's seat will become your favorite place for listening to music once this Prime amp goes to work.
You might think you don't need an amp because you have a 400-watt system in your car, or because your new stereo puts out 50 watts a channel. But those are peak wattage ratings, which may boil down to 15 or 20 watts per channel, using the more realistic RMS rating. An amp sends your speakers the power they need to deliver your music with clarity and impact, whether you're using factory speakers or high-performance components. And low-frequency reproduction requires lots of power, so an amp is an absolute must if you're adding a sub to your system.
I replaced a monoblock fosgate 400w amp with this one. The monoblock was driving 2 8in fosgate 2 ohm speakers wired in series. I upgraded my door speakers and tweeters to the fosgate P165-SE component speakers so needed a multichannel amp to drive them. This amp does a great job driving the component speakers AND drives the subs much better than the monoblock amp, even though its wired to 300w on the subs and the monoblock was 400w. The system sounds great and the amp has a small footprint. Plenty of power for my system.
Pros: Good power, easy to install, included remote is nice. Crutchfield support was great throughout the process
Great item-easy to install-replaced my alpine with this one-works great
Pros: Easy install-better controls on crossovers an gain controls
Bought this for my 16 year-old son as a Christmas gift to install in his Mazda Tribute suv. He was previously running factory speakers off of an in-dash powered CD player. We replaced 4 speakers, installed this amplifier, and hooked up a 12" Kicker subwoofer mounted in a box. Needless to say, he is impressed with the power, the much improved music clarity, and the bass. We are still fine-tuning the cross-overs and gain adjustments, but really like the amplifier. Our Crutchfield advisor was very helpful with the purchase, the installation instructions were informative, and the order arrived within 3 days. I felt like the price for this sized amplifier was reasonable and we are very pleased with the purchase.
Pros: Provided certification from Rockford Fosgate says the amplifier tested at 726 watts vs. 600 as advertised. A lot of fine-tuning adjustment available for the user. Very good unit for systems running only one amplifier.
Cons: No complaints at this time.
It works great. Easy to install
This is an excellent purchase for the person who's looking to match treble with bass using only one amp.
Like most Rockford amps, the advertised power is about 17% less than the power stated on the Certificate provided in the box; therefore, this amp is really putting out 60 x 4 @ 4 ohms and 350 x 1 @ 2 ohms. The crossover functions and bass boost remote help tune the system for a well-balanced mix for all types of music.
Pros: Best bang for your buck.
very good product
Pros: very powerful
Cons: overheats and shuts down at times
Was a great amp, replaced my 2 channel and and used this for my subs and a pair of 5.25s and 6x9s. It made my system sound a lot louder and crisper.
Pros: Power/can't go wrong with rock/fosgate Crutchfield support is amazing
Cons: Price is a little higher than id like
Was a little disappointed in the lack of power it had for my application. Returned it for replacement Crutchfield was great as always
Pros: Remote punch adjustment
Cons: Not enough power for my system

Overview: The Rockford Fosgate Prime R600X5 is a 5-channel amplifier, with full range two 2-channel amps and a mono subwoofer amp built into one chassis. The front and rear amps are class A/B with identical but independent controls (gain, crossover, Punch EQ). The subwoofer amp is class D with its own gain, crossover, phase, and Punch EQ controls. The front and rear channels are bridgeable, so the amp can also be used in 4-channel or 3-channel modes.
CEA 2006 Compliant: The R600X5's power ratings and signal to noise ratio are measured according to the uniform standards advocated by the Consumer Electronics Association (CEA). This allows you to accurately compare these specifications for all CEA 2006-compliant amplifiers, even from different brands. Manufacturers who adhere to these standards can display the CEA 2006 logo on their products and packaging. CEA2006 Specifications for this amplifier are:
LED Indicator: The amplifier is equipped with an LED power/protect indicator. The LED illuminates blue when the unit is turned on. It illuminates red if the thermal or short circuit protection circuit is engaged, and the amplifier will automatically turn off.
Mounting: The amplifier can be mounted vertically or horizontally using the supplied mounting screws. The amplifier should never be mounted in an engine compartment as this will void the warranty.
Gain Controls: The front, rear, and subwoofer amplifier channels have independent gain controls. Each rotary control is labeled 1 to 11 and has a sensitivity range of 150mV to 4V when using the RCA inputs, 450mV to 12V when using the speaker level inputs.
Remote Punch Level Control: The R600X5 includes a wired Remote Punch Level Control, linked to the gain control of the subwoofer amplifier. The module allows you to remotely control the output level of the sub from the dash or center console. The Remote Punch Level Control features a rotary dial, and comes with mounting hardware and an 18' cable.
Note: The Remote Punch Level Control measures approximately 1-3/4" wide (2-5/8" including the mounting flange) x 3/4" high x 1-5/8" deep (2-1/8" deep including the knob and wiring).
Crossover: Each section of the amplifier has independent crossover controls:
Punch EQ: Each section of the amplifier also has independent Punch EQ controls:
Phase: The subwoofer amp has a 2-position phase switch to allow you to easily reverse the output phase of the amplifier, choose 0° or 180° to match the rest of your vehicle's speaker system.
Power Terminals: The power and ground terminals are nickel-plated set screw terminals and will accommodate up to 4 gauge power and ground wires.
Fuse: An external 80-amp fuse (not included) must be installed on the power wire at the battery. If a wiring kit is used which includes a fuse with a value other than 80-amps, the original should be replaced with a 80-amp fuse.
Remote Terminal: The remote turn-on terminal is a nickel-plated set screw terminal that will accommodate up to an 8 AWG wire. It's used to remotely turn the amplifier on and off.
Speaker Terminals: The five pair of speaker outputs are nickel-plated set screw terminals what will accommodate up to 8 AWG speaker wire.
RCA Input Jacks: Front, rear, and subwoofer RCA input jacks provide an easy connection for preamp level inputs. They are nickel-plated to resist signal degradation caused by corrosion.
Speaker Level Input: Two speaker level input harnesses are included, making it easier to add the amplifier to a factory radio or to a receiver with no preamp outputs.
Wired Remote: An RJ-25 jack is used with the included Remote Punch Level Control.
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere. That's because we have our own in-house Product Research team. They verify what’s in the box, check the owner's manual, and record dimensions, features and specs. We stay on top of new products and technologies to help people make informed choices.
You can use the 4-channel setting and the sub will still work when wired to the subwoofer channel on the amp, it's just that you won't have individual crossover/filter controls on the subwoofer channel in that case. If you wanted that ability you'd need to use an RCA splitter to split the rear outputs and run a separate RCA cable to the subwoofer input on the amp. This Monster RCA "Y" adapter would work well for that: http://www.crutchfield.com/p_119ILJRY2F/Monster-Cable-1-Male-2-Female-RCA-Y-adapter.html [ Larry Dec 26, 2015 ] Staff
The first four channels have HP/LP crossovers and are bridgeable to 2 channels. 150w x 2 RMS. The 5th channel IS a dedicated sub channel with 200w RMS @ 4 ohms and 300w RMS @ 2ohms. Presently I have a four channel Axxera mini amp running my front speakers (Polk Audio components in all four doors), and the 600x5 in 3 channel running my mid-bass Kicker 6 3/4s and a Rockford 12" HX2 (on the dedicated 5th channel). In your set-up, if you wanted to add some mid-bass, (80Hz to 250Hz), you could feasibly do so by using that 5th channel. It will NOT be in stereo, but it could be done. Or, if the worst happens and you fry your dedicated sub amplifier, you have a backup in the 5th channel. If you're asking about that 2ch/4ch/5ch switch, that's for input. The 5 channels on this amp can be used solely from a 2 channel input, (unlike my digital Axxera amps, lol). Feel free to ask me more questions anytime. Fritz [ James Dec 03, 2015 ]
If you have a radio with front and subwoofer preamp outputs, then I would set it to 5. Otherwise, I would set it to 2. [ Paul Nov 03, 2015 ] Staff
Yes, all of Rockford Fosgate's amplifiers are CEA compliant. [ James Aug 28, 2015 ]
I forwarded your question to an Advisor and they responded with the following: The RMS power output per channel on this amplifier is 50 watts RMS at 4 ohms and 75 watts RMS at 2 ohms. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat. [ Krissy Dec 21, 2014 ] Staff
May not be a good one to ask since I myself thought it was short on power & punch so I returned it to Crutchfield [ GREG Oct 08, 2014 ]
That depends on the output of your Subs. If they are 150 each then it would work but it is always better to be a little over powered on the amp side of things that way it does not have to work as hard. If I drive a 300 watts in Subs then I want no less than a 400 watt amp. 5 Channel amps are nice and cost more but you could buy 1 amp for your speakers and buy another just for the amps. I use Crutchfields house brand amps and they work great. You can buy 2 house brand amps for less than you would pay for a 5 channel amp. That will leave you money to buy cables and wire [ DUKE Oct 08, 2014 ]
It powers a single 12 just fine [ Eliseo Oct 03, 2014 ]
