Extremely good valueAug 10, 2010
By A. Bush
"mechanical engineer"
UPDATE 5/10/11:
I have owned this amplifier for about 10 months now and I use it nearly every day. The amplifier still works perfectly, even after sliding around in my trunk due to my lazy "mounting" system (which is nothing at all). I have never felt that the sub doesn't deliver enough bass or experiences clipping or distortion due to the amplifier. I believe that the amp is actually more powerful than what I need. I have also put it to the test of endurance. I did a 14-hour nonstop drive to southern California, during which time I played my stereo constantly. The amp is still perfectly fine. Rockford Fosgate has made a very high-quality, reliable and durable product with the R150-2. I still highly recommend it.
ORIGINAL REVIEW:
I bought this amplifier to power a JL Audio 10" W1V2 subwoofer (with an RMS rating of approximately 150 watts).
The amplifier arrived in high-quality packaging and included a certificate of testing, indicating that prior to leaving the factory it had functioned properly and produced an RMS wattage higher than its rated value. The set included the necessary fuse and some mounting hardware.
The amplifier is a typical Rockford Fosgate high-quality product. Fit and finish are excellent and the product has a clean, simple design. The terminals and adjustment controls are rugged and well-labeled.
Using a Rockford Fosgate installation kit, which I would recommend due to its similar good value and inclusion of all necessary cables, I was able to install this amplifier in my 1998 Kia Sephia in about an hour, including routing the power cable through the engine bay firewall (the most difficult aspect for me). I connected the signal and switch-on leads to an Alpine iDA-X200 receiver.
Note: After installing and connecting all cables, be sure to turn the gain on the amplifier from "1" (which amplifies by a factor of 1...in other words, not at all) to a higher value, such as "10" for maximum power output. Otherwise, you will not be able to hear any output from the subwoofer or speakers. Also, if connecting to a subwoofer, be sure that the subwoofer is turned on and up to an appropriate level via the stereo receiver.
Once I got everything set up correctly, I tested out the amplifier and was extremely happy with its performance. The bass from my subwoofer is clean, tight, and very loud, and by turning the "bass boost" feature on this amplifier to about halfway, I have more than adequate output with my subwoofer set to 5 of 15 on my receiver.
The best part of this amplifier is its price. With a name like Rockford Fosgate and more than adequate performance for any reasonable music enthusiast (as long as your goal is not simply to be heard from blocks away), you would expect a higher price, but the R150-2 is one of the best value amplifiers that I was able to find, and I am absolutely satisfied with my choice.
I have had this amplifier for a few weeks now and its performance continues to be flawless. It does get very warm, like any amplifier will, but keep enough airspace around it and there should be no problems.

good amp but payed 100Dec 31, 2010
By cory
i bought this amp at a local audio dealer and same with the rockford p1 10" sub. And now looking at the price on amazon i should have came here first since i payed double at the local dealer when i bought it in june. but overall this is a good amp other than the fact it overheated once and since then no issues.
Best amp ever made!Sep 20, 2011
By Wheat
This amp arrived in about 3 days after I ordered it, it was in perfect condition. The amp was very easy to put in, good directions. Now as far as sound quality I've never had better sound! This amp is amazing, it's pushing my 12" kicker no problem, and it's not even turned half way. I would recommend this amp to anyone who wants great sound quality, and a very good price. Thanks for reading.
