Product Description

Discontinued - Replaced by the s2

   Introducing the new Symphony series amplifiers. These amplifiers are the results of over 2 years of from the ground up development.

The goal was to combine high fidelity signal clarity to an extremely efficient Class D full range circuit topology, housed in an ultra-compact newly designed Crescendo Symphony heatsink.

Comprehensive signal processing on the multi-channel Symphony amplifiers, such as bandpass capable crossover circuitry and individual clipping indicators for each channel make the 2 and 4 channel Symphony amplifiers some of the most versatile on the market.

All Symphony amplifiers are capable of being mounted in constricted areas of your car install if needed thanks to the dense form factor and effective design of the heatsinks.

The final outcome of the PCB design enables up to 97% efficiency @ 2 ohms on the monoblock Symphony models and up to 91% efficiency @ 2ohms per channel on the multi-channel models, making them the top tier of efficiency possible in car audio.

  1. Perfect!!!! 5 Star Review

    Posted by on 23rd Sep 2015

    Crescendo is the best!!! A lot of these big brand names are over rated. This amp is powering 8 tweeters with ease and it sounds crisp. My money was well spent.

  2. Crescendo has done it once again 5 Star Review

    Posted by on 28th Jan 2015

    This is the 3rd amp (bc3500 & c1100.4) I've purchased from Crescendo and once again the quality blew me away. Don't let the size fool you, this amp packs a punch. So far I only tried it on a pair of 10" pro audio speakers and a pair of pro audio tweeters and it sounds great. I want to try it on a pair of 8" subs after I finish the box for them. I'm sure it won't let me down.

  3. smallest 550.2 i ever had 5 Star Review

    Due to the high power output to size ratio these amps are perfect for limited space. Not is this amp small it does rated power and you have to love clipping indicators.
