What sizes are the factory speakers on the doors and rear deck...

[Gerry24]

I have an 03 and it has an amp in the trunk that looks factory.

[RubberCtyRauder]

Is it a black box mounted under the package tray or front part of trunk on driver side?
That is the subwoofer..or is it in a plastic box on the left floor above the deepest part of trunk? that is the cd changer

[jwibbity]

Factory sizes are 6X8 in both the doors and rear deck

[Gerry24]

Yes, is on the drivers side.... Looks like an amplifier

[RubberCtyRauder]

Post a pic, but that is where the subwoofer is if up top . Could be aftermarket

[Gerry24]

I'm going to have to take the spare off and inquire further, just purchased my MM on 1/17 it's an 03 300a built 8/2002

[RubberCtyRauder]

I guess there is an amp with it , subwoofer inside

[2mercs]

Drivers side mounted to the rear deck would be the sub and amp. Plastic box with a silver i believe amp mounted to it.

[Gerry24]

Here's one

[Gerry24]

Sorry about the lighting

[RubberCtyRauder]

Yes there is a amp, the black box houses the subwoofer. Mine has been replaced by aftermarket prior to me purchasing so my memory is a little off on the factory one

[boatmangc]

If you are comfortable with it, 6x9 can be fit into the rear deck with a little cutting.

[Gerry24]

Is the sub a ten inch?

[RubberCtyRauder]

No, it is like a 6 - 6.5 inch

[Gerry24]

I'm gonna have to open that up to check it out...

[RubberCtyRauder]

If you open it up, take the round foam baffle out..reportedly it helps a tad with sound

[jwibbity]

The only reason to mess with the factory sub is to remove it, very little bass response, sounds like crap, and its not worth any effort or money trying to "upgrade" it.

[Gerry24]

Ok, so just remove the amp and speaker when I up grade the system...
