bose sound system

On my way to salvage yard. Need to replace my antenna. Looking to make a few upgrades to my 05 Tahoe z71 and I know this is the place for ideas and advice

I just bought a 2005 chevy tahoe and I tried to wire up two 10" jbl 1000watt subs in parallel with an Autotek m4000 amp. I've got a little experience wiring subs and I've wired my own in a 2000 impala but I wired these ones and they do not work, the owner before me wired up a touch screen...
