I have a 1993 252 BR and the from bow speakers are half covered by the upholstery padding (I should have got a pic).... I was wanting to upgrade then but can only access the lower two bolts, any ideas? Also how is the best way to run the wires for new speakers under the bench seat? I looks like it will be challenging to ad new speakers as I can't access the gunwale areas. Thanks for any help or ideas!
