Radio in my 2007 tahoe

I was wondering if I could get some help here?

I have a 2007 Tahoe non bose and I was wondering if I could exchange my non DVD radio with a DVD radio out of another 2007 Tahoe?

I know that it will physically fit but my question is about the plugs on the back where I only have 2 the DVD radio has 4. I do not know if im right but im thinking that one of them is for power one is for the mids and hi's one is for the woofer and amp and the last one is for the video. but that is a guess

any help would be very appreciated

are you referring to this radio that you bought ?

that radio came with A/V plug, 4th plug you should not worry about, that one is only if you had a Denali.
if your tahoe is non bose, you need to add a little 4 channel amplifier,

Yes thats the radio i bought. Why would i have to add an amp. i think the radio has a built in amp. i thought the amp in the bose was just for the sub woofer
