Every time I connected my ipod to the in-jack of my stereo in my new Tundra I got a loud hum noise that drove me crazy! Those guys knew exactly how to fix it (for next to nothing) and was ALSO able to help me upgrade my front door speakers to ones that are 500 better and actually fit. Crutchfield sent me two sets of speakers that would not fit so I gave up...should have gone to Big Daddy's in the first place. I will from now on!
