Amazing Amp!

I purchased this amp and I love what it can do! As most have previously stated, the amp pushes more than the 750w @ 1ohm as stated. The birth certificate with mine rated is at 880 watts. I am a HUGELY loyal RF amp and sub person but have always been leary of buying their PRIME line of products because they aren't "supposed" to be Fosgate's best line. This has changed my mind on the PRIME line. This hits just as hard as some of my older previous PUNCH and POWER amps!
I have it powering 2 RF P2's @ 1ohm in a ported box that I got here at Sonic Elextronix (P2-2X12) and it has almost rattled off the rear view mirror on the windshield!

Love this amp!

This amp is awesome! Love everything about it! Rated for 750 rms but most of them are over 900 rms @ 1 ohms (that will vary per amp of course) gotta love rockford for throwing in birth cirtificates and extra powa!

Rockford Fosgate R750-1D

When I first received it I realized that it was smaller than a previous Rockford Fosgate amp I purchased so I was worried it wouldn't push the full power it says it can output. The birth sheet that came with it says a total of 916 watts RMS @ 1 ohm sitting at 14.4v of course. This amp has some serious power for being so tiny! It outputs clean strong power that doesn't lack even on a hot summer day here in California. As the matter of fact I was able to drive from Fresno, CA to Pismo Beach, CA which is a 3 hour long drive and it never shut off on me.
I would recommend doing the 'Big 3 Upgrade' on your electrical system so you don't put so much stress on your battery and alternator. I recommend you buy this amp especially since it offers almost 1,000 of true power without leaving the wallet empty.

Right choice

I thought this amp would not be able to drive my p3-12 Rock ford Fosgate sub but it gave me a big surprise, i bought this amp to add a little base to my factory stereo and i have no regrets if you are looking for a nice upgrate for your factor stereo well this is one of the best amp on the market thanks to sonic.

the little amp that could

this is a GREAT amp it pushes what it says and over and I know for a fact that it's .5ohm stable or can push it

this amp is probably the best ive had in a long time... it preforms about like a punch 600.1 I would even say thats it's closest retaliative.

Awesome!

I have this product hooked up to an 10" atomic subwoofer and my head unit is a double din pioneer. It is rated for 400 watts at 4 ohms and this amplifier matches it perfectly, although on the box it did not say it was rated for 400 watts at 4 ohms like it does on the website. The remote bass accessory that comes with this is a must! It is so easy to adjust the bass on the go and I use it all the time, and although there is a light on it that is quite bright, it turns on with the amp so you always know when it is on, which is nice. I will buy another Rockford Fosgate Product.

Tiny amp with alot of heart!!!!!!!!!

I recommend this amp for a two sub combination, my amp birthsheet was 918 and i have 2 re audio srx 12s in a slot ported box and this amp pushes those 12s with ease. A must buy, don't let size fool you. Durability is Rockford Fosgate.

Wow!!! Power just as you would Expect from Rockford Fosgate

I purchased this 750 watts RMS amp to push 2 Sundown Audio SD2-10's in a behind rear seat box for my 13' Tundra Crewmax. It came with a birth certificate that said 872 watts RMS. I can honestly say with the FOX Audio ported box it sounds like I could compete i Bass competitions. I have it down really low and it still POUNDS. Powerful Amp well worth the money and the body is small so you can install it anywhere.

great product, loud, accurate and efficient

I enjoy it immensely, upgraded from an older Crossfire amp and there's a big improvement. it can handle my Rockford Fosgate Punch P3 Series Car Audio Subwoofers P3D4-15 Punch Series 15" Subwoofer

love it, if you have to want an extra month for money, do it, It'll probably outlast your car and sound great in the process!
