Review: Sweet. 4 AWG wire and a 50 amp fuse - Ordered yesterday, got the vehicle ready today, the amp came and I am thumping! Sweet. 4 AWG wire and a 50 amp fuse. 950 amp battery. no cap - but I'm considering one now. I will see how the lights stay stable or not tonight.If they dim I will order the cap and install that too. So nice and small. almost half the size of the DUAL it replaces and considerably heavier. This is in a 2007 Caravan with a factory amplified system with a aftermarket JVC head with USB port to play We play many genre of music and have added tweeters and a 12" Titanic Mk IV. With my other amps that I tried (small and medium DUAL and something else too) Sure I had BASS, but very little really I had the last amp hooked to signal level inputs from the amplified speakers and it was all dialed up. pretty unsatisfying really. not that I am against the DUAL amps, I have DUAL amps in two other vehicles and they do very well, just not with this setup. This Fosgate is in with everything at about medium - middle of the road on the head unit, the gain and the punch settings - I have the crossover at maybe 80hz and the infrasonic filter at about 30hz. I am using the Sub out RCA on the head unit (ugh, put a RCA cable back in!) and this is all I need. The sub sits between the front buckets. Nice near-field experience. The mirror or the glass moves and the view in the mirrors gets fuzzy and I feel fully bathed in rumbling BASS finally. So here is a 750 amp @ 1ohm pushing my 12" 4ohm at 250 amps. The amp turns on and off with the amp control wire from the head unit and the soft turn on it working fine - no thump on start up or shut down (else I would have to fix as she will not tolerate the thump at turn-on) I do not have the remote (which it came with) installed, just the wire run, so I cannot comment on its function at this point. Its awesome. Now I can borrow this, the wife's van and run the whole day delivering when its my turn and enjoy the music, whatever music I want it has BASS now. My birth sheet says 888 amps BTW Review: Worth every penny - 7/3/2019 Going on 8 months of daily use now. I added another 8 and am running it at 1 ohm. No problems with heat at all. The subs are rated 400 watts rms and this amp pushes them to the max and beyond if I would let it. Very good amp. I've had it hooked up for a minute now and it's running a skar 8 at 2 ohms and it sounds pretty good. Waiting to get my box for 2 8s so I can see how it sounds at 1 ohm. The amp itself was fine and looked new. The box was a whole different story. It looked as if it was used. Spoke with seller and was assured it was new. Corner was smashed a little and the seam where it opens was wore. ## Features - Class D - 750W - Mono Block ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004T166L8 | | Best Sellers Rank | #265,005 in Electronics ( See Top 100 in Electronics ) #565 in Car Mono Amplifiers | | Brand Name | Rockford Fosgate | | Customer Reviews | 4.6 4.6 out of 5 stars (367) | | Global Trade Identification Number | 00780687333133 | | Item Dimensions | 9.1 x 6.8 x 2 inches | | Item Weight | 5 Pounds | | Manufacturer | Rockford Fosgate | | Model | R750-1D | | Mounting Type | Car Mount | | Number of Channels | 1 | | Output Power | 750 Watts | | Package Type Name | Retail Packaging | | Specification Met | FCC | | UPC | 613815588757 780687333133 | | Voltage | 12 Volts | ## Product Details - **Brand:** Rockford Fosgate - **Item dimensions L x W x H:** 9.1 x 6.8 x 2 inches - **Manufacturer:** Rockford Fosgate - **Mounting Type:** Car Mount - **Voltage:** 12 Volts ## Images ![R750-1D Mono Block Class D Amplifier - Image 1](https://m.media-amazon.com/images/I/71iayidwk+L.jpg) ## Questions & Answers **Q: have a sundown sa-12 d2 will this supply enough power and if so how should it be wired?** A: Depending on the subs ohm rating. I'll assume it's a two ohm dvc sub. In that case you'll get the complete full power of the 1 ohm amp. Which is 750 watts Assuming the sub is not internally wired, meaning there is two positives and two neg. coming out of the sub, then you would take both positives wired together and both neg. wired together. You would then connect the two positives to the right channel positives on the amp then take the two neg. and connect those two to the left channel neg. on the amp. This would give you the 1 ohm load or full power of the amp. Now if your sub has only one pos. and one neg coming out you would wire it the the same way with the pos wire going to the right pos. on the amp and the neg. going to the left channel neg. on the amp. The amp itself totally rocks out but the manufacture also advises getting a capacitor or cap to help when hitting heavy bass for continuous periods. I ended getting a 1.5 farad digital cap. Which is rated for approx. 1500 watts RMS., more the enough for the 750 watt this amp can produce. Though the cap. Is not required, you'll will def. hear/feel the difference in bass with one. Just a side note, the amp is rated for 750 RMS minimum. Rockford tests the amp before it leaves the factory and assigns a " birth sheet " stating the actual watts that exact amp produced when tested. My amp birth sheet stated my amp can produce 943 watts RMS. Pretty sweet. That rating can only be achieved with the proper wiring. Meaning using 4/6 gage wire and assuming your vehicle can keep the required 14.2 volt Continuously, that's where the cap. comes in. To keep the juice flowing at a continuous 14.2 volts. The cap. Is bought was purchased for about $50. T-Spec V6-1-5DDC Digital Capacitor 1.5 Farad Digital T-Spec V6-1-5DDC Digital Capacitor 1.5 Farad DigitalSold by: Amazon.com LLC Happy thumping! **Q: Why does it have 4 speaker outputs do i bridge if only hooking up 1 sub** A: It is a mono block, meaning only one channel pos and neg. But it has A and B connections, they DO NOT count as separate channels. It's just to make things easier if you planned on several subwoofers for an install. This amp is stable down to 1ohm and will easily exceed the 750w RMS rating, for instance my birth sheet shows 940w RMS tested before they boxed it up.So be careful when choosing your subs. I run a single Rockford P3D2-12in wired in parallel to 1ohm. Make sure your sub or subs can in total handle more than 1,000W max. If not, you are likely to burn up your voice coils with this little knock out amp. **Q: So either where u hook the sub you can get a 1ohm load the two speaker output is not a left and right channel am i correct** A: It has 2 negitives and 2 positve out puts just connect 1 pos and 1 neg its gonna be the same ima is. 1 channel amp at 1 ohm **Q: Is this as good as a JL audio amplifier ?** A: Never owned a JL Audio but, this Rockford is definitely worth it's weight in gold. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Sweet. 4 AWG wire and a 50 amp fuse *by H***D on January 28, 2015* Ordered yesterday, got the vehicle ready today, the amp came and I am thumping!

Pushing a RF P2-2x12 box. Sounds solid on the base. Way into the damage your hearing levels. Love the adjustments. I somehow skipped over the fact that it didn't have high level inputs so for my installation I needed to buy a converter. I opted for a Kicker unit over the RF unit only because the kicker had level adjustments that could be made since I didn't know how it was going to preform when connected to the amp. Running it and another RF amp on a 3 F cap, System is working great on a stock battery and charging system no complaints. The base adjustment knob is a must as well since base levels seems to be so widely varied by one artist's music to another. ## Frequently Bought Together - Rockford Fosgate R750-1D Mono Block Class D Amplifier - Rockford Fosgate P3-1X12 Punch Single 12" Loaded Subwoofer in Ported/Vented Enclosure - Rockford RFK4X 4 AWG Complete Amplifier Install Kit --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.es/products/1164816-r750-1d-mono-block-class-d-amplifier](https://www.desertcart.es/products/1164816-r750-1d-mono-block-class-d-amplifier) --- *Product available on Desertcart Spain* *Store origin: ES* *Last updated: 2026-05-23*
