Electrical noise, like a tea kettle

[rammie 10+ year member]

Had 2 amps (1 forsub and 1 for front comps) installed and had a quiet electrical noise. Sub amp removed due to bad outputs and now the noise has increased in volume. Coming through the speakers, and it loudens/quiets when i step on/off the gas. Sounds like a wailing like a tea kettle. Any ideas on what is causing this? I cant get back to the installer for awhile, so im hoping i can take care of this in the meantime...

thanks for any assistance
