REaudioBuff Posted August 10, 2010 Report Share Posted August 10, 2010 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?

Eric B Posted August 10, 2010 Report Share Posted August 10, 2010 Are you stacking your connectors on the battery posts? That'll do it...

TeejayBee Posted August 10, 2010 Report Share Posted August 10, 2010 im gona answer with a someone question but could it be that your slaving it ? due to the fact your slaving one it has to lose some power for the other to get Quote Link to comment Share on other sites More sharing options...
wL<3bass Posted August 10, 2010 Report Share Posted August 10, 2010 What are you talking about the input voltage or output voltage on the speaker terminals?

REaudioBuff Posted August 10, 2010 Author Report Share Posted August 10, 2010 (edited) 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....

Buss bars imo are more clean and organized and won't suffer all the resistance from the way your doing it now.

Loudcivic Posted August 10, 2010 Report Share Posted August 10, 2010 (edited) how r u testing voltage between the 2 amps? Edited August 10, 2010 by loudREcivic Quote 2015 silverado crew cab nothing atm but soon... Link to comment Share on other sites More sharing options...

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.

REaudioBuff Posted August 10, 2010 Author Report Share Posted August 10, 2010 how r u testing voltage between the 2 amps? dmm plus the led on the amp itself shows it.. plus its not as loud... something is wrong its like a batt is bad or something idn...

dugee81 Posted August 10, 2010 Report Share Posted August 10, 2010 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?
