Review: Hooked up with RF Prime 10" and my car thumps! - I wasnt looking for the loudest bass in the world more then quality good sound so I chose this amp with the Rockford Fosgate Prime 10" Shallow Enclosure to add to my system thats currently in progress. I have it hooked up to a Boss dvd in dash that was also bought off desertcart and its 85x4. The hookup was pretty simple it going into a '08 Toyota Corolla. I wanted to just get a nice upgrade from stock without trying to take out my whole trunk or make my car rattle apart as ive done with a prior vehicle on 4 18's. I I wasnt expecting this amp to do much being the rms being so low and the sub looking so small when I looked at it but I tell you once I ran everything and tuned it this bad boy gets it. Smooth clear bass and gives the perfect amount I was looking for in such a small package. For the price and the overall quality by doing the prime series its been great. Ive had mine in now a couple weeks and it makes me look forward to driving again. Im actually upgrading my door and rear speakers and tweeters with the prime series this next week to complete the package. I would recommend this to anyone wanting great value and amazing quality.
Review: Awesome is the only title needed here. - I bought this with the R400-4D and made a simple plywood mount which I then put behind my F-250 passenger seat. (regular cab) I also ran 8 gauge from the battery and connected the ground to the frame underneath. I am using a pioneer DEH-8400BH. For speakers I went with a 10" box sub which fit perfect behind the middle seat (ok not a seat) and 2 8" on the doors and 2 enclosed sony speakers I Velcro to the cab corner which fits tight with my seat back. It all sounds simply amazing. I now realize the importance of doing things right ( I know I should have done 4 gauge :( ) but using this class D system is so much better on my truck. My previous Class AB really got hot and sucked the life (amps) right out of my truck. This is the Amp set you were wondering about. You just can't go wrong with these two units. I may want to upgrade my pioneer next if anyone has any good ideas. Anyway right now its the best stereo I've ever heard in a truck.

### ⭐⭐⭐⭐⭐ R250X1 is under rated!
*by D***T on February 25, 2014*

I received my amp and the first thing I saw in the box was an official "birth certificate" from Rockford Fosgate that said that the actual RMS output of my amp was 308 Watts. As expected it seems that RF under rates their amps. I was glad to see this as I paired the amp with the Rockford Fosgate Prime R1L-2X10 Double R1 10-Inch Preloaded Enclosure which is rated for 300 watts RMS. This amp is quite small too. About 11x9x2 inches. One thing I want to say is that my original plan to wire up the amp with the high level speaker inputs was not going to happen. Basically I wasn't able to output more than 1 or 2 volts to the subs from the amp while attempting to use the high level inputs. (I used a DMM to set the gain and playing 57hz @0dB at 75% volume on the stock head unit (22) which meant that the output voltage should have been at around 24V to prevent clipping) Unfortunately I wasn't even able to get 2 volts from the high level inputs so basically I had no choice but to use the LOC for my install. As far as the amp performs it's great. It hardly even gets warm. I am pretty pleased overall with how well the amp plays and the fact that it includes the remote bass control knob. But make sure you use an LOC. And just as a tip the settings I use are -Punch EQ: Min -Freq: between 60-80hz -Gain: This will depend on your individual setup, use a DMM! Take the actual RMS power and multiply it by the ohms of your sub. Then find the square root of that number. That is the target voltage output you will be looking for (AC). So then you want to play a tone at 50 to 60hz @0dB at 75% of your headunit volume and with the sub disconnected slowly raise the gain until you are just under the target voltage and you will be safe.
