  1. This amp is a beast

    Posted by Unknown on 21st Sep 2015

    I heard about this exo when he installed these and he described it as adding way more authority to his systme. That is the best way to to describe it. I've got it on 2 ohms with some infinitI subs (not the greatest but they'll get me by). People say it gets hot pretty fast, I haven't experienced that. Needless to say I will be ordering another one once I get some new subs. Definitely impressed with this amp, and the customer service at SSA.

Product Description

Introducing the new Symphony series amplifiers by Crescendo Audio. 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.
