Hey peeps just got my Install done and want to share!! I dove in and replaced my 2011 MTX tower speakers with 4 Exile SXT65Q's, Harpoon amp, and a ZLR! Supper happy with it all! As a matter a fact the ZLD is a epic $200 purchase!
I Custom installed the ZLD below the throttle in the cubby hole. This thing rocks! It amplifies the signal from the head unit and helps the amps not work so hard. Then the zone control lets me control the volume from my cabin to tower with a separate sub control.
Then toss up 4 swivel mount "Surf" speakers that are loud enough for boarding and crazy loud for cove parties. But I had to order larger clamps due to Axis's tower being the largest tower around at 2 7/8". Lucky that Exile had this figured out for me. I also had to drill new holes in the tower cause the speakers were so large.
Here are the picks of the install. Oh and by the way Brian at Exile is a superb contact. He was available always to help tune or questions for the install! So nice working with these guys.
