I didnt read too many comments on this thread, in my Taurus i have Diamond Audio 12's w/ Diamond Amp. My front door speakers are 6.8 DB Audio and i had my rear doors custom-made with DB Audio 4.5 speakers on each end. Sounds alot better through-out the car i could def. tell the difference. Also have a 2400watt Digital Capacitor. If u dont have the money to put into your car dont waste your time...dont live beyond your means. Im 22yrs old i was in college when i was in the U.S. Air Force as a Military Police Officer. Now i drive 18wheelers across all 48states n Canada, n ive invested over $17,000 into my car. But in my city..Birmingham, Al i have a guy that has done everything u can do with cars for a little over 13years and he told me the door speakers to get, fitted and cut them into my doors..wired and installed including the speakers themself brand new for $115.
