First of all, you have to know that I'm a computer guy but not a car or audio guy. However, after doing a lot or researches on this forum, I think I got enough information to start buying the stuff I need for my CarPC installation (the PC is already bought, it's just eagerly waiting to be in my car!). I started from 0 with the power scheme and I came with this :
I have a couple of questions related to this:
1: Can I use smaller wire than my distribution block accepts? (ie: 14G for CarPC instead of rated 8G)
2: Regarding question #1, can I use 2 different wire and fuse sizes? (ie: 14G and 15A on one side, 8G and 45A on the other)
4: My car is a 2004 Mazda 3 GT. I noticed 2 tweeters near the mirrors. Are they actually working and, if so, are they linked to the front speakers or do they have their own channel?
5: I might purchase another amp and a sub (or self-powered sub) and/or replace the stock speakers next year. Should I go ahead right now and install thicker wire and a bigger fuse on my main power cable? Could that hinder my current setup knowing that the second amp is not there yet?
Thanks in advance for your help and time.
