  1. Real Power

    Posted by Frank on 11th Feb 2015

    I hooked my 5500D up to my Massive Summo subs.. Within 4 hours of play.. It blew them out of the Box..

  2. gorgeous amplifier that is a pure beast period.

    This amp is so gorgeous and its a beast. I always run top tier amps and i just pulled a very respectable amp that i wont name out of my ride and installed the bc5500. I love it so much i just bought another one today.

  3. Got SPL?

    Posted by Wade H on 2nd Sep 2014

    Well after 3 months of waiting i finally get to see what all the hype is about with Crescendo Audio. The BC5500D is a beast of an amplifier. I have two 12 Ascendant Audio Mayhems wired to 1 ohm so each sub is getting roughly 2900 watts. Now the subs are responding like they should, compared to the Hifonics Brutus x14 2600D which was previously pushing the subs. The lows are crazy. My windshield wipers flex now like never before and when i'm driving its hard to see when those lows hit. I used the SMD DD-1 to set the gain so i know the subs are getting a clean signal. Only one day into ownership and so far i am very happy. The price for this amp should be doubled!! Hurry up and get one or two before Navid realizes he is giving these things away. 5 stars all day long!!!

  6. bad ass amp!

    Posted by Brandon Lee on 10th Jul 2013

    I got one of these on my four sundown sa 15s at 1ohm with 2 of the crescendo group 31 batteries just doing some testing with just battery power still waiting on my alt to come in this amp puts out lots of power but doesn't hardly use any. Can't wait to get my singer alt in and really unleash this monster! The only thing in my car that isn't crescendo is the wires and subs. Crescendo audio FTW!


    Posted by Riley Gress on 4th Jul 2013
