He's already installed a PAC iPod adapter, so he didn't need a new deck installed.....so I simply installed a new PAC interface behind the stock deck to give me Audio Outs.....put the amp under the driver seat, which is covered nicely by the floor mat, and the sub is easily removable if trunk space is needed.
Thing pounds for a 4 channel amp.......which means the customer will be back to install a good front stage speaker system down the road.
Cheers!
