Glad you guys are digging on it!!

Can you post a final summary of all equipment used? Can you elaborate a little on how the arduino control is set up (hardware and software)?
Summary of equipment used:Power
36v li-ion 9.6Ah pack (x2) - powers the whole system
36v to 12v stepdown 10A - powers all 12v accessories like, pre-amp mixer, dj controller, laptop charger, miniDSP
5v stepdown 3A (x2) - powers arduino + LED's
15ohm 25W precharge resistor (the classdaudio amps together have 10000uF of capacitors to fill
, without the precharge resistor hooking the power up resulted in a damaging power spike and arcing on the battery terminals)
Turnigy watt meter - monitors amount of battery usedAudio
TI-300 classdaudio amplifier
TI-600 classdaudio amplifier
miniDSP power isolator - filters out the noisy 36v to 12v stepdown and provides 12v to miniDSP and pre-amp
Rolls MX122 minimix pro (steel case removed)Visual
Arduino Uno R3
Bliptronics spectrum analyzer - reads a 7 band EQ into the arduino as separate values
Sparkfun WS2801 led strips (x3)DJ
Traktor Kontrol S4
The arduino is set up to control a set of DPDT relays that connect two pins I discovered on the TI amps to enable standby mode. When the pins on the amps are connected, standby is enabled. Using a pin on the arduino I time delayed the ON state of the relay so that the amps start up a few seconds after the system gets power. This protects the amp from the dreaded "pop" noise and damaging the system. Also I have a blue kill switch that changes the state of the amps after the system is started up.
The arduino also controls an array of 88 LED's I installed on the back of the bike. They are all sound reactive based on a 7 band EQ shield made by bliptronics called the "spectrum analyzer shield". This thing is way rad because you can literally make yourself a parametric EQ or just sample low bass and highs as I have done with the back of the bike. I am now at the point of being able to spend some serious time programming LED patterns, so excited to see where that goes. I have a little control panel I'm making that sits next to the gear shifter that will give me turn signals, stop / go LED commands, and cycle through LED pattern programs.
We just did a ride this past Saturday (this bike's maiden voyage) and I had barely enough time to make a basic LED pattern that mimics the lows on the sub and the highs on the tops. Also there is a nightrider mode
Much more to come as far as LED patterns, and maybe tonight I'll get some video of it too.
Thanks again for all the compliments, I'll be back on here soon with some more progress
