The turbo sound is probably a power wire run to close to something like the alternator and there is an interference...

Be more specific on the 'thunder' noise??

usually low pitched sounds not instructed from the HU are the result of improper grounding. Usually. How would you describe your ground? Is it lacking in any particular way?

Is it sanded good? Is it in a good spot? is it bolted tight and well connected?

it is your ground, i am 100% certain of it.

could be your HU ground or your amplifiers ground. try them one at a time, and make sure they are solid connections.
