Default Amp install

Can I split the front left and right speaker outputs coming out of my factory head unit so I have four inputs going into my amp or do I need to use the front and rear left and right outputs to go into my amp giving me four?

You can split them just fine, lot of folks do. Why not use the front and rears tho so you can have fade ability?

It depends on what amp you are using. For example, if using a stinger spx 700x4 you don't need to since it has a 2-4 channel input switch. If you leave it in 2 channel input, it will deliver the signal to all 4 channels. If using a sound digital amp then you will need 2 splitters to feed all 4 channels.

Depending on what flash you have, you wont have fade control. A 8/2 flash doesnt allow fade control to work.

I am using Kenwood KAC-M3004. I am only using the two fairing speakers so I don’t need fader capabilities. I can’t afford bag speakers or flash so I’ll keep using split front left and rights for now. It seems to be working. Unless I’ll get more power or better sound by a flash and using the rears to get four inputs?

You need to flash the head unit. If not you are taking a chance of blowing the amp and/or speakers.

That amp doesn't take speaker level inputs. So you will have to run a line out converter (speaker input to RCA output) and then split those RCA to all 4 RCA inputs on amp. Like Gypsy said, I wouldn't do it without a flash. Find $100 and go get flashed. Don't even worry about lid speakers. You're looking at approx $1500 to add lid speakers to make it worth it while riding down the road. Spend your money on your fairing.
