You should try grounding all of your stereo equipment to a common point.
Also, don't ground directly to the battery, but to a good chassis point.

Finally, make certain that all of your high and low levels are seperated
from one another, dont bundle them together.  This means speaker, line
level, and power.

You should have no problem with 2 amps as your equipment seems to be of good
quality.

You can finally try a noise filter if you have a bit of noise after trying
the above, this may only get rid of the last bit of noise when you have all
of the bugs worked out, it is not a band-aid.

Good Luck,
Anthony
