Snib,
That "coil" is actually stamped steel...it acts as duct work to move air to the side vent and as a collapsible support should your knee smash into it in an accident. Now that you have the underdash removed you'll have to lay down on the floorboard and look up into the dash near the firewall. The amp is bolted to the brake pedal pedistal, held on by a single bolt with a 10mm sized nut. You only need a 10mm box wrench to remove. Word of caution here, when reinstalling the amp you have to hold the bolt into the pedistal with one hand while placing the amp on the bolt with the other. Much easier said than done. The head of the bolt rests in a hexagonal recess which holds the bolt. I hope that is clear enough.

Also, as for GDL...I highly recommend then too. Got my amp rebuilt by them, turn around was something like 3 days - one day up, one day in and the third was shipping back home. Cruise amp has worked perfectly since installation just before leaving for Michigan. Peter does good work.
