Sound System Upgrade

[smh12]

Hey guys,

To start off it’s great to be on this forum and it’s going to be good talking to all you guys, also I had no idea where to post this so if it is in the wrong area let me know and I will move it.

I want to upgrade my cars sound system. actually, I wanna make more sounds so I think I should change my speaker and replace with good one. so guys any help? or do you have something that can help me? BTW I visit this site https://www.icrfq.com/ there is many of them, So I can't decide. this is why i am here .

Welcome to the Forvm! It would be helpful to know the year, make and model of your car, and what system it has in it now.

OK,,,, I don't think he is coming back,,,, So I'm on here looking for information also.
I have a 94 mustang I think it came with the premium sound system It has 1 amp in the front only.

I would like to switch it over to mach system. I have the rear complete set up speakers and amps and the wiring harness to go up to the front.

How many harnesses will I need up front?
Can I reuse any of the harnesses I have now?
Do the speakers in the door have a spacer between the door and speaker? < needed with after market?
Will the upper speakers in the door have wires already ran?
Any tips?
