Cobra29 and amp problem

I have a Cobra29 NW Classic in my truck that works great . When I hook up a
kl203P 100w amp and hit the RX button all goes quiet when it should really boost reception. I tried the amp in the house and it works perfect. I’m running the amp straight from the battery too. Any ideas?
thanks
