4. ground amplifier using stock ecu location
5. wire the remote to the head unit
6. wire up to my components.
7. check all wires for TIGHT SNUG, AND CORRECT POSITIONS IE. POS iin pos... neg in neg...

finally turn it on, no power to the amplifier
I DON'T get what i'm doing wrong someone help ahh

You grounded it to the ECU ground? No. That's not a threaded hole and is a poor ground for a large supply like an amplifier. You can also cause interference in the car by doing so.

Where is the amp mounted? Ground it to a BOLT, like a seat bolt, shock tower, something solid and substantial.

Also, what is this 150A fuse you mention, and where is it? The power lead should come off the 100A fusible link in the car, then within 18 inches have another fuse inline, but I would say no more than 50A, the amp cannot pull that much current.

yeha, i grounded it to the ecu ground.

the amp is just sitting under the car seat sitting on the bare carpet.

the 150a fuse is what came with the jl audio wiring kit, it looks like this

100a ---- 4 awg wiring--- 150a ---- 4awg wiring directly to amp.

i checked all the fuses they dont look blown hehe.

the the power doesnt even turn on lol, so either i have a defective amp or i'm doing something terribly wrong.
