Removing the old, cracked 4" speakers, and putting in some 5 1/4" Memphis Audio Power Reference Component speakers.....cutting the existing door panel to put the woofer in and placing the tweeter in the stock speaker location.
I offset the tweeter inside the existing 'grill' because the speaker, from stock, is partially blocked by the dash...so this way the driver gets a clean, unblocked path from the tweeter to his ear.
Doors also got a good layer of sound deadening to help with the road noise.
Vanagon sounded MUCH better than before....next is a newer deck with hidden iPod controls and better subwoofer settings.
