hi, I'm looking to buy aftermarket speaker for all of the doors in my car. can anyone tell me the actual size of the speaker in the doors? Thank you.
What year is it? They are 6 1/2" mid bass but the fronts I believe are 8ohm and the rear 4ohm or vice versa. From what I've read a co-ax will sound like poop. If you are just wanting to replace with stock make sure you get the right speaker for either front or rear.
The speakers are not actually a standard fit. The woofers are approximately 6.5", but not all speakers listed as 6.5" will fit. Best to use a compatibility guide, like the one at Crutchfield.com.
Aside from physical fit, it's pretty complex to get aftermarket speakers working right in these cars. The impedance IS different front-to-rear, but the fronts are 4 Ohm and the rears 2.
If you have the standard system, the signal is fed to the the woofer, which has a built-in crossover to feed the tweeter at the top of the door. If you have the premium Monsoon system, it's bi-amped, with a separate signal feeding the woofer and tweeter. Either way, you can't just replace a driver and expect it to sound right. (Granted, some people some combinations of "incorrect" pleasing, but it's not accurate sound)
If you MUST, for some reason, use aftermarket speakers, you pretty much have to replace them all, either installing coaxials and disabling the existing tweeters; or install components (and crossovers).
If Monsoon, you have to replace the amplifier as well, because the amp is calibrated to the response of the Monsoon speakers - won't sound right with others.
Now- WHY do you want to replace your speakers? The existing system is actually pretty good...
