Re: installing 4x10 speakers in the back of a 1984...
I can't remember your car exactly but if your speakers are in the rear deck, you often times have to start by removing the bottom portion of the rear seat, then the back portion of the rear seat, then the deck cover. Sometimes the side plastic pieces have to come out too. It's a pain but that is the way it gets done.

Say your doing a car install and the speaker wires arent marked with a positive or negative symbol and you cant get to the back of the speakers or/and it would take a lot of extra time to take the doors apart so you can get to the back of the speakers,all you simply have to do is take the two wires coming from the speaker,grab any AA battery and put one wire on the positive side and the other wire on the negative and as your doing this observe the speaker and see if the speaker is sucking in or out.If it flexes out,then that is right and whatever wire is on the positive of the battery is your positive of the speaker and naturally the other one is negative.If the speaker flexes in then that is wrong ,just switch the wires and that will let you know which is which-Have Fun and Always unhook your battery when doing install-Thanks Steve
A little bit of information I will need before I can give any helpful answers. First, did you use a wiring harness to install your radio. Second, is there an amp involved in the system. Let me know by posting again. Thanks
A good place to at least find out the size is www.crutchfield.com They have a great vehicle database. You can purchase from them or from somewhere else. When you find them. Then you can go to www.wound-repair.com to find install instructions or purchase the ones from crutchfield. Hope this helps

Well, good luck sir. Your'e going to have a lot of cancellation and possibly some blown speakers out of al of this unless you actually build a box around the back of all of the speakers. the subs are fine but there will be issues with the speakers. Either way figure out your own loads of all and have 1 2 channel amp for the speakers or multi channel for the speakers and a mono for the subs.
well caddys have (most likely) has a low grade HIGHEND name "entertainment" system...a.k.a BOISE , JBL etc. it wont mess anything up I dont think..BUT it wont work...you need to speak with a INSTALLER and get the right wireing harness chang over...My LINCON M8 has a JBL and we just ran new speaker wire and by passed the stock cross over and amplifire ....but you cant just hook it up and have it work..
