Why is one amp 1.5volts higher than the other?


Recommended Posts

I have 2 RF t2500.1bds... I'm confused as hell about this problem.... I am using master slave on my amp and one amp is 1.5v higher than the other... Its connected correctly, and that's exactly how meade is using his. Any opinions? What to check do change?

What are you talking about the input voltage or output voltage on the speaker terminals?

no it would only be a drop of at max like .2 volts from slaving it... and should i just like buss bar all 4 batts rather than having wires between them all? maybe that would make them all fire evenly over the amps? I mean thats my only idea really...

Edit: Talking about the input voltage at the + - inputs....

Well when you keep stacking the connectors it gain LOTS of resistance. Buss bars imo are more clean and organized and won't suffer all the resistance from the way your doing it now.

do you think that will fix alot? or do you think i might also have a fuse blown or something of that nature? I mean this weekend im going to take my subs and box out and re wire the batts re fuse it all and hope that solves it. But im just looking for ideas as to what else could help.

Try re wiring. Like make it so amp 1's power wire is where amp 2's power wire would be, and vice versa see if the resistance theory holds up. If you notice the slave amp is still at 1.5v less than the master.. Then idk? Jus throwin suggestions out
