How high have you set your gain?

Does it get louder as youe accelerate?

Its not that we dont know, its just most of us have day jobs, or live in different time zones.

That's your problem, gain is ALL the way up. Turn your gain down, it's NOT a volume control slappy.

i have a similair issue, but usually it means there is bad ground, run the negative straight to the battery terminal

could be that the power antenna wire (the blue one, goes to the amp to tell it when the HU is on) is loose, so the amp is turning off and on. could also be that the power and/or ground doesn't have a good connection.
grounds should be as short as possible.

Every serious SPL competitor does exactly this. It's done to create a direct and uniform ground path to help their amplifiers make maximum power. Rather expensive for non-competitors, but worthwhile for someone who's trying to extract every last watt he/she can.
