300 Watts in an Ultra-Compact Amplifier

CEA-2006
Power ratings on Rockford Fosgate amplifiers conform to CEA-2006 industry standards. These guidelines mean your amplifier's output power ratings are REAL POWER numbers, not inflated marketing ratings.
Discrete Surface Mount
DSM--An industry-leading manufacturing process, DSM utilizes high-speed robotics, high-quality 1% tight-tolerance parts and large board traces. The discrete components are laser etched to meet a particular value and a very low tolerance. This lower tolerance improves the efficiency of the circuit, decreases cross-talk from other discrete components and lowers operating temperature. These superior components are used by aerospace, automotive, and cellular manufacturers.

Customer Reviews


This amp is the revised version of the 8104D. If you read those reviews, you will see mixed reviews... on the good.. they praise the power and sound quality... on the bad they complain about overheating issues. I just installed this amp today... cant tell you extensive reasearch type info but I have a JL 500/1 to compare to. This amp says 500 watts just like my JL but for the stereo noobs out there... these are NOT in the same class... JL is higher end audiophile quality while this kenwood was made for budget-minded people who still want quality. This amp pushed my JL 12w6v2 just fine but I had a hard time getting the gain just right... I was getting distortion at higher volumes but it may have been due to my MP3 player being up too high. This amp did not make my car lights dim like the JL does and I dont have a capacitor either.
I rode around for about 4 hours bumping the system with the JL sub in for about 2 hrs and it never cut out or seemed to overheat at all. The amp is fairly simple to set up... took me 2 hrs from start to finish and I had to run all the wiring in my GFs car.
Overall great quality and for the price... I dont know if there are others that can compare... Highly recommended for someone on a budget(like most of us these days) who still wants to get a little more out of their system without breaking the bank.

Boss Audio R1100M Mosfet Monoblock Power Amplifier with Remote Subwoofer Level Control


Product Description


Your first view of the RIOT Series may deceive you. The elegant lines are a textbook exercise in minimalist design. From this point on, however, its power and reproductive authenticities will be anything but minimal. Perhaps the only thing more extensive than the features showcased is the enjoyment you'll derive from them. This is only one reason BOSS Audio has led the way in 12 Volt Entertainment for almost a quarter of a Century.


Customer Reviews

For anyone looking for a good, cheap, and reliable amp this is it. I have two 1100 watt 12'' Sony Explods hooked to this amp and they hit hard and sound clear. The company should actually charge more money for this amp and for its price you cant beat the sound and performance it puts out. I was impressed by this amp and it has done more than what i thought it would for the price. This amp truely is 1100 watts. For someone starting on a budget i would say this is the amp for you. It doesnt get overheated and if it does it has a protection system built in so you dont blow anything. This is a good quality amp that i truely think would be good for anyone starting on a budget or looking for a good replacement amp.
