Free speakers. Should I install them?

[Truckin1999]

I have a 97 Blazer sitting around that I used the drivetrain out of for another project. Well I've still got the body, and I've been trying to sell it for parts. I sold the passenger front door to a guy who didn't need the interior panel. To my surprise when I took the panel off I found there are Pioneer 3-way 6.5" speakers in there. They are some of the better Pioneers even though they are a few years old. I haven't checked the back doors, but I'm hoping they have a set there as well. My question is whether or not you guys think they would be worth swapping into the Vibe. I have the M&T package so that would help with the sound quality if I do. I've used Pioneers in my other cars, and from what I can remember they hit the high notes, but are lacking in the mid and bass department. I have a set of 6x9 4-ways in my Blazer and I like them, but they are just there for the treble. I have a sub to cover the bass. I just wonder if the tiny sub in the Vibe is enough to make up for the lack of bass in the door speakers. I don't want to go through the trouble of changing em out only to find out it sounds worse than the stock M&T. What do ya guys think?

It would be a good start... Adding some sound deadening to the doors while you have them apart would be an even bigger improvement... You also only need sound deadener near the speakers (maybe extended out 12" or so) to do the job, to do it right, you would want to cover everything, but to get started AND hear a noticeable improvement, add some sound deadener... It gives the speakers something to work against.. I like to use the "coffee can" anology... tap the side of an empty coffee can... you know the outcome there... now, fill it with water and try again... you just added sound deadening to the coffee can... works the same in the car, you just aren't using water... lol...
