Symphony S800/4 4 Channel
Product Description
Discontinued - Replaced by the s4
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.
Dimensions:
s800/4: 11 1/8" L x 7" W x 2 3/8" Tall
S550/2: 7" L x 7" W x 2 3/8" Tall
S600.1: 6 3/8" L x 7" W x 2 3/8" Tall

vocals on point!
Posted by MyBeardBringsAllTheBoysToTheYard on 29th Nov 2016
Running this beautiful amp on my 4 crescendo neo forte 6.5s in my doors in my tahoe, absolutely screams and crystal clear! Love the unassuming size of it as well, small enough to tuck under a seat or a fender well if need be, but I like mine Seen in all its glory running next to my bc5500! Don't hesitate to purchase, does everything it says it does and looks sexy while doing it! Great company to support as well!

terriffic amplifier!

I'm new to using crescendo as this is the first amplifier I had purchased from them. Absolutely crystal clear through my mids and tweeters while also having the efficient class d. Used the LP filter and sounded good as well. Shipping came fast and the crescendo team were excellent in their custom service.

Very Impressive little Amp!
Posted by Lincoln Kestner on 22nd Apr 2015
I was in the market for a very long time for a new 4 channel amp. I have been running all of my speakers for the last year off of a Sundown SAE 50.4 and was really not getting the power that I was wanting. I then started to do a lot of research and stumbled on this little beauty. The first thing that you notice when you get this amp is its size. This amp is small!! Then after you hook it up you realize that not only does it have amazing crossovers and very good output but at 2ohm this amp is a little monster!! By far the best 4 channel amp that I have ever purchased and will for now on will only run Crescendo Audio!!

Best 4 channel amp on the market, great sound Quality
Posted by Jeff S. on 29th Mar 2015
i was deciding from this amp and the rockford t1000.4
and as everyone knows that amp is not cheap. i own 2 bc5500 so i thought i give the 800.4 a try. MAN THIS AMP IS THE STUFF!!! so much power for being so small. The Sound quality is amazing.Crystal clear. so Glad i went with it.
This amp was also Tested on the SMD meter and well outperformed its rated power (another reason why i went with it) i would 100% recommend this amp over any other amp. GREAT JOB CRESCENDO!!

tiny powerhouse
Posted by Unknown on 12th Dec 2014
For it's power, this amp is very small. Fits under the driver seat of a 3rd gen ram with room to spare. A couple of the nuts that hold in the RCAs were loose out of the box, but easily snugged back down. The build quality of my BC3500 is at least a couple of notches higher with more solid looking RCAs & metal pot nuts vs plastic on the S800. This amp replaced an arc xdi804 and sounds much more defined. The xdi was clear, but just didn't satisfy me musically and didn't get nearly loud enough to overcome road/engine noise inside the cabin @ freeway speeds. The S800 is rated at over twice the power of the smaller xdi, but it definitely shows in my application. This thing makes my cheap pioneer 6.5" components play with authority now. Not sure how long they can take it, but they seem to be doing just fine. I like the amp overall & I'm happy with my purchase. Thanks Crescendo!
