FiBTLforlife Posted September 17, 2009 Report Posted September 17, 2009 so im working with this kicker sx 600.4 amplifier that was given to me by my best friend. Long story short, someone didnt know what they had and just said take it for no charge so i got this FREE. Well the amp powers up fine, but has no audio output from amp, inside looks pretty clean no burn marks that are noticable, just needing advise on where to look at first on amp. thanks guys P.S this amp might be used in my 8 5.25'' tang band sub build 2 AQ 10'' HDC3 copper subs 1 3500d AQ amp 146.3db on TL with stock electrical in single cab truck at 32hz RESULT: 1st place at comp, 3rd overall out of 20 cars

Boon Posted September 17, 2009 Report Posted September 17, 2009 Check resistance between RCA centers and outers and the spots on the board, could be cracked solder join. Then work your way through the amp. Though if you don't have a scope it makes life hard. 10.x volts fo' life!
