How do I replace my 6x9 speakers in a 02' Grand AM with Monsoon Audio without replacing entire audio system?

Question

I have a blown right-rear 6x9 speaker in my car and have asked many different store "specialists" what to do. No one seems to want to work on Monsoon systems. I have NO desire to spend the kind of money needed to replace both the speakers, head unit, and amp. I just want to pick-up a good pair of 6x9's and replace the speakers. I know very little about car audio install and replacement, but any sort of help would be awesome, diagrams, web-links, pdf. file......anything. Thanks!!

Answer 1

Here's how to replace a Monsoon 6x9" speaker while retaining the factory amplifier:

When you remove the stock speaker you will see a 4-wire plug. Two of the wires are directly connected to the woofer in the stock speaker, and two are connected to the tweeter. These are different outputs from the factory amplifier, so don't combine them.

First, you need to identify which wires connect to which part of the speaker. Then you'll need to modify the replacement speakers that you're putting in.

With most after-market 6x9's, you can separate the wiring going to the mid/tweeter from the wires going to the woofer. If you look closely at the terminals you should see two small wires soldered to the terminals and running up through the rear of the speaker, through the middle of the magnet and to the tweeter pod. You'll have to cut these wires and connect them to the wires that connect to the tweeter in the stock harness. The wires that connect to the stock woofer can be connected directly to the new speaker terminals after the tweeter wires have been disconnected.

If, understandably, you'd rather not modify your new speakers, then you can simply connect your new speaker directly to the factory wires that ran the woofer in the stock speaker. What will happen is that the new speakers will play only the bass, but usually there's enough treble present on the front speakers that a lack of treble in the rear doesn't hurt anything. If you're just trying to get rid of a crackly blown rear speaker, then this might be the way to go. If not, you can always modify the new speakers later if you decide you'd rather have them playing the full sound range.

im not sure how the grand ams are set up so first check your trunk and make sure its not held from the bottom. if its not then you have to pull the carpeted piece off the back that covers the speakers, take out a couple screws to remove them, switch the wires from the old speakers to the new and put the new 1s back where the old 1s were. it should only take you 20min-1hr.
as for speakers do u have a stock head unit or something aftermarket? i would go with audiobahn as69q you can get them at onlinecarstereo.com for $69 and they sound amazing.

if the person below me is right thats another reason to go with the audiobahn as69q 6x9s, since they have a removable tweeter and will be much easier to connect to the seperate tweeter wires.

Answer 3

you have to remove the seats and the rear deck cover to get to the speakers

remove one and go to a car audio store or radio shack so they can check the speaker most moonson use 4 ohms speaker
that means that any speaker will fit,
If the speaker is a 2 ohms you need to find the original
www.oemautosound.com have them and they are not to expensive

Answer 4

K-zoo is 100% right on the wiring. grand ams are a b*tch when you want to keep the monsoon. here is a link that will help you remove the rear deck lid.
