hi i need help to rewire my head unit. ok when i first got my system i didnt know anything about wiring them so i had a guy help me that use to work at a audio shop. my setup was and still is one amp powering my sub and a 2 channel amp powering my door speakers and my head unit powering 2 tweeters w/ cross overs taking the bass away from them. now i would like to run my door speakers and tweeters off of my head unit. from the head unit the white and gray both w/ black strip are going to the tweeters, green and purple are taped off from the hu, now the wires coming from the sub for the door speakers are running into the stock wiring harness those 4 would be the purple, white, gray, and green w/ black strip. so can i just splice the stock harness into the ones coming from the hu. im assuming this would be a typical install correct far as the door speaker wiring. i have a 97 f150 if that helps any. and one more thing i wouldnt have to worry about the cross overs for the tweeters if i splice before correct. i think im right so let me know. thanks in advance guys.

p.s all my audio is pioneer
