THANK YOU

for purchasing a JBL Grand Touring

®

Series subwoofer. 

Subwoofer installation requires woodworking skills and some
experience in disassembling and reassembling automotive 
interiors. If you lack the tools or necessary skills, have your 
subwoofer installed by an authorized JBL dealer.
