Audio System Guru's...need a little help.

[Lunchbox]

I am working on my dash in my spare time when I cant get over to my car. So I am in the process of having the dash frame painted in the next couple of months. I would like to have the dash cut for larger speakers before I do this. My dash is a 3 speaker dash and was plaing on putting the infinity 3.5's there for the center I was thinking of putting two tweeters there instead of the 4x10. One reason behind this was a friend of mine said that haveing a odd number of speakers with a system is hard to do.

I plan on putting a hidden head unit, and maybe having the rear 6x9's amped along with the other combo I stated above.

Need anymore info let me know...and as always thank in advance.

should work great , I have installed 2 3" speakers in the center speaker before , an extra 1/2 " in the corners should work great as well , I have installed remote stereos in the glovebox in the past

Can anyone give me a rough distance between the back of the glove box and what ever is directly behind it. I think it will be the heater box. If it is the heater box a A/C style would be perfered.

Thanks
