KevinMowens Posted April 27, 2012 Report Share Posted April 27, 2012 I got an 05 trailblazer and I got my 4 channel hooked up with my new speakers. I haven't thrown in my sub yet because I want a new battery first. The 4 channel is a rockford punch 425x4 or something and I have a saz1500d. I also have a Xs d925, so along with the 3400 should I expect any voltage drop? Quote Link to comment Share on other sites More sharing options...
Dangrebel Posted April 27, 2012 Report Share Posted April 27, 2012 Yes you will still get voltage drop. The battery's act as a storage and when the voltage drops to about 12.8-12.9 that's when the batts are used.
