I've tried searching the forum for bose and subwoofer and for some reason nothing pops up. Sorry if this has been addressed. I've got an 08 tahoe LT with bose, center console and factory nav HU. I'm trying to figure out if I have a factory amp and subwoofer in my console. Is there a way to know without tearing the console out? I'd like to add an amp and subwoofer in the rear and want to use my factory HU. I don't want to cause any interference issues with anything like getting the white noise issues or reverb. Would I have any issues installing my aftermarket subs and amp regardless of factory equipment? Very new to messing with the audio in a newer vehicle. Thanks for any help.
