Do I need a distribution block?

[idkcaraudio]

Oem fuses EVERYTHING. How big is the factory fuse on that wire? If you can run both your new amps without blowing the fuse or replacing it with a larger fuse then you are good. It makes no difference whether you T off or use a distribution block as long as the joint is solid and insulated/protected properly.

No idea how big the oem fuse is, I haven't check, but I guess it doesn't matter at this point because I decided to go with using new 12v lines for both amps. Thanks though!
