Need help with amp noise

[Motofox 10+ year member]

Hi all, I recently installed a JBL 4 channel amp in my car, and four JBL speakers as well. But when I turn the volume from 0 to 1, the amp noise can be heard. If I turn the volume up more than that, the amp noise level remains the same, but the music gets louder. Here is a schematic of how my audio system is set up, I followed the step by step advice at crutchfield also, so I'm not sure what exactly is causing the noise. Any insight would be greatly appreciated, and if you need pictures of anything, I have the interior of the car taken out so that would be no problem. Thanks!

can anyone tell me what might be wrong with this setup? am i supposed to have that loop triangle from the battery to the engine to the wheel well and back to the battery? Should the ground to the amp be in a better place?

The wire from the alt to the battery should be 4 gauge. Also the ground wire should be the same as your power wire. So basicly anything that you have 10 gauge should be changed to 4 gauge.
