I have a 2005 GMC Yukon SLT with the Bose system i found the amp under the center console, then yesterday i found a amp behind the glove compartment. Is this normal? I have read many posts on here saying its supposed to be in console but when i was doing stereo work yesterday i found the other, looks like its hooked to the rear speakers but not sure. Is the amp in the console hooked to the subwoofer or what? thanks for any help you can provide.
