I added speakers to the westy....once I figured it out , no handle hitting
speakers, no handle extensions. I used Pioneer speakers front and back
model # TS-G1047 .Where the stock speakers are, With bass blockers. I
unscrewed the speakers out of the mounts, popped out the old speakers, got
a dremel tool and cut the hub the held the stock speakers, the pioneers
come with little black screws that can use to mount the speakers. The
screws are are mounted on the outside , the old speaker grill, was cut
flush with the dremel.That's it

For bass I added to 8 inch speakers in the cabinet the makes the lower
bed.With a Kenwood mounted inside the cabinet of the lower bed.

My 2 cents
