Quick overview of the Speaker/LED system:

Speaker Amplifier: Kinter MA-170 Amplifier, 2 x 18W
Microcontroller: Arduino UNO
Speaker: 5" Peerless Driver, 8Ω impedance, (http://www.madisound.com/pdf/peerless/831990.pdf)
LED Driver: Adafruit Motor/Stepper/Servo Shield for Arduino v2 Kit - v2.3 (https://www.adafruit.com/products/1438)
Misc: LM358 Operational Amplifier

Wonjae's disassembled the old plastic case recently and milled some MDF for a new housing. Yesterday and today I fixed some of the walls and today I tested it. Whatever problems were supposed to exist with the sound is nowhere to be found - it works fine. The mounting for the arduino needs to be fixed. The terminal strip needs to be mounted. All internal wiring needs to be clean up. A spring for one of the 4 speaker outputs from the amp fell out so the speaker is now using the other channel.
