Metra also makes various speaker adapters if you decide to change the size of the speakers in the door. There's a nice plug and play harness for our trucks that Metra makes for the door speakers so I'd consider that if you want super easy install there. I'm not sure how much juice the Sony factory amp has but I'm assuming it's more than the non-factory unit. If anything, you may want to consider looking for a set of speakers that are 90+db in rating to get more "volume" out of the factory unit/amp. Which option above will produce the best sound? Am I missing any affordable / simple options? I am not an audiophile, just want to get a cleaner sound from the stereo, I do not see adding a processor and amp at a later time. The way I see it I have 3 optionsġ) component speakers, run the door speaker off the existing wiring, wire the tweeter with the crossover with the factory tweeter power as the crossover inputĢ) component speaker, put the crossover in the door for the woofer with the door speaker power as the crossover input and buy a set of base blockers for the tweeterģ) buy a 2 way speaker for the door and disconnect the pillar tweeter I want to replace the factory front speakers but do not want to cut or tap into any wires (cutting the wire to the tweeter in the pillar OK) and with the way wires are run from the body to the door, I do not want to attempt to run a wire from the door to the body. I put this over in the stereo forum but did not receive any responses.
