Need confirmation on my setup (+ some quick questions)

**zak_mckraken** · 06-14-2009, 12:08 PM

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.

It looks like a relativly solid setup:

are you planning on using a amp that you already have? the 600 watt amp is really overkill for factory interior speakers, and most aftermarket speakers.

1. It is not really recommended, but can be done, I have done this by striping more wire and doubling it over to fit the connector.

2. if you use a fused distrobution block, then yes.

]. I don't have any knowledge on the factory audio system in the mazda 3, so I can't be certain. the easiest way is to turn up the treble, and listen for them. if they are present, then you will need to determine if you will need a crossover for them, or if there is already one built in.

5. it will only hurt your wallet now, but can save you time later when/if you do decide to upgrade.
