I'm planning on buying some Polk Audio DB651 speakers (the DB651s for the front and the regular for the rear). I'm seeing all sorts of stuff about custom 3/4" spacers for mounting. Will the included mounting bracket not work for an '08 WRX? I'm not an audiophile, just want better than stock stereo. How necessary is a spacer? Could I get away with a generic 1/2" spacer from amazon?
Also, I'm planning on using a baffle to protect the speakers. Any concerns using those?
Any help is appreciated!
