Adding more Speakers to 93 Cav

The other day I went to the junk yard, lookin in cars for some good speakers. (I was not satisfied with my rear speakers) And came across these awsome Boston FX8's. Their only 5x9's, but they looked like they were in incredible shape. I snatched them, and went to look some more. I found this pair of 100W speakers with huge magnets. THEIR MINE! i said, as i stole them from the car. hehe. I went and payed for them, (only 5 bucks a pair [canadian]). Now, as soon as i brought them home, i took out my old rear speakers in my 93 cavalier, and replaced them with these. I was suprised that they did not give much trebble, as they had a seperate tweeter on them.
Today, i went on the internet and searched up my Boston FX8's that i got for $5 in excelent condition, and found that they sell from manufacturer for $119.99! So, seeing that, and as they got some really nice sound to them, i was wondering if there was any way that I could make another hole for them and mount them beside my other rear speakers. Is it possible? When I mount them, do I just use screws?
Please help, i'm really hoping to get them into my car. Thanks.

Wait, i have an idea. Tell me if this sounds good. I'm gonna put my 5x7's in where the rear speakers go. And since my 100W ones i got have great bass, im going to build a small box for them in the trunk that faces the back seat. Will that work ok?

you can do anything you want and set your mind too.. You may get harassed if you make it look ghetto, but if you are good with fiberglass... make a custom spot for them in the rear dash...or even use the side curtain and glass a spot for them in there.. i think that would look deacent...

These make my car sound real nice....

don't mind the dirty floors... it was winter is these pics..

your better off putting them in your car somewhere and not the trunk. they may not sound as good in the trunk. the back seat may quiet them a bit.

01 cavy's right. The back seat will drown them. you're better off going with your original idea. take the carpet, etc. off the rear deck and find a spot to make a hole for the other two speakers and cut new holes out for them and mount them with screws. You may have a problem running them in series with the stock deck though, I'm not sure if they can handle the resistance being cut in half.

Duct Tape always adds style :grinyes:
