I currently have a Subaru Legacy 2010 that is still under warranty and wanting to install aftermarket subs/amp without voiding the warranty which specifically states no aftermarket modifications. However, I plan on installing them anyway, and then take them out and hide the wires where there not easily noticed when I go for oil changes and other things.

Anyway, I have developed a system that still has a few bugs but thankfully it's getting better every day. I'm a bit low on money, so I have shortened my upgrades down to just a few things (since my stock stereo already blurs the mirror just a tiny bit) which doesn't break the bank.

First things first, it CAN NOT appear that I have modified the car. So that limits me to the stock head unit, which would be more than obvious if I replaced it. Anyway, I planed on wiring it up to a diagram similar to this..

This is where I start to have a little trouble understanding. For starters, what kind of power wire (blue wire) should I be running from the battery. I've seen people say 8 gauge, 10 gauge, and a bunch of other things. But what should I be using? If you could even link be to the best deals that would be great! Exactly what kind of wire should I be running from my amp to my subs? From my converter box to my acc. plug and my speakers? I really need to know exactly what wire I should go in the store and buy.

As far as converter boxes go, what would be the best converter box (high/low or line in line out) should I buy? Also how should I be getting the wire from the speakers? I could not find a wiring diagram anywhere, and my car does not feature back speakers that can be access through the trunk. It appears that I need to access them through door panel? Do I just soder a wire to the speaker and run it, what kind of wire do I soder? Or could I somehow find the wire in a more convenient place before it enters the door and splice it somehow there? (I have a Subaru Legacy 2010)

Also I'm looking for the best enclosure for my steup? I plan on building one in the future but for now I want a prebuilt enclosure. I understand there not the best, but what would be the best one to get?

My last question is with the battery fuse. What fuse should I buy and how far should I place it away from the battery? I've heard many different things from many different people.

Thank you and if anybody finds a diagram for the speakers in my car that would be great. I can't find exactly where to get my front deck speaker wire for my LOC box. Also if you have any tips for hiding things in the easiest way possible when I go take my car in don't hesitate to let me know!

Go with the biggest wire your amp will take. The bigger the wire the better. Power goes through quicker. I had 2 4 gauge wires on like an 800 watt amp now I have 4 gauge and 0 gauge on a 1100 true watt amplifier. Go with the Biggest your amp will take is all I can say. not 8 or 10 that's what I use for speaker wire and my system isn't that big. My friend is putting 4 oc (0 guage is 1 oc) on his amp that is only takes 0 guage. Amazon is the best place to buy this stuff.

Oh and for the fuse I'd say use an 80a that's what I used. My old system was similar to yours.
