Quick advice needed on unfinished amp install

[GreenSpeed]

Hey guys-

I am below a novice when it comes to audio stuff, but I always like to learn by trial and error so I decided to undergo the process on my own. I have a single amp connected to the factory HU and a small sub in the back, but cannot get the amp or the HU to turn on when the ignition is turned 2 clicks and even when the car is started.

I followed the crutchfield guide as closely as I could, but when I turn on the car, the HU and amp do not power on.

Here's a quick summary:

-Power Cable from Amp Power through firewall to 80 amp fuse, then about 6 inches to positive battery
-Remote power spliced from blue cable on blue harness from factory HU. I simply cut the blue cable a few inches from the HU and spliced in a new remote wire into the existing two.
-Grounded on a well sanded and exposed bolt about 4 inches from amp, which is under the passenger seat.
-Obviously the factory HU doesn't have RCA's, so I spliced new speaker wire for all 4 speakers from the blue harness and their indivual colors based on the wire reference guide in this forum. The speaker wires are running to hi-level inputs on the amp (ran the RCA's from the stereo area to the amp without connecting them for future ease of attachment)
-Sub is connected to amp without power

I can't think of anything else. Can someone tell me why my amp and HU aren't turning on? I tested the blue remote wire before and after cutting it for splicing to make sure I had the power wire.

Really appreciate some quick advice as I have my car apart and need to drive the car tomorrow morning.

Thanks!!!!
