FACTORY STEREO 03 AV SUBWOOFER QUESTION

[03AvvyRedneck]

Hey all, i haven't scoured the pages yet since i am a new member so please forgive me if i seem redundant.  I have an 03' Avalanche, Z66 with the Bose sound system. 
1- does the existing OEM stereo Head Unit have RCA jacks already in it?
2- If not, I have a self powered sub that i wanna hook up. How can i do that?
3- Can i still hook up to the factory deck or do i need to go get a double din aftermarket unit?

Side question- what size screen do i purchase for my double din factory unit replacement?

1 - No headunit does not have RCA's. You can add them with convertors but they are not there normally. Not worth it..
2 - You can tie into the subwoofer output but again, not worth it. New radio is better option.
3 - The head unit has front and rear powered outputs so you need a Line level convertor to convert power to low level. Or you can tie into the amplifier outputs which need a line level output convertor that can handle that extra power. The factory subwoofer is a dual voice coil 6" sub woofer mounted at the front of your console. Assuming you have a BOSE setup. If you don't have a BOSE setup then I don't believe you have an amplifier and just comes directly off the head unit.
