I tried to gain match my amp off the tutorial on JLAudio but all I keep getting on the amp's channels was 0 volts. Gain down,0, gain up zero. Nothing made it change, but the subs did work. They still do but it sounds like **** and needs tuned in.

 

Are you using AC, or DC to check voltage???? I bet you need to change off of DC. Meters don't lie, if they are being used properly.

 

hmmm, i got this from a buddy who is a mechanic and has like every tool imaginable but the settings were dcvolts/4ohm/4kilohm/4megaohm... and i was using dc

 

You need to use AC not DC on the meter. You are measuring for Vrms which is a AC voltage.

 

Thanks for the help

 

ya and amp is basicly a votage converter well alot more complicated but thats what it does. if you had a strong enough amp you could power some power tools off of it.

 

Yeah with a 60 Hz sine wave.....

 

Do I really need one of those sine wave cd's to tune in an amp or could I just use a cd? Where would I buy one of these?
