Here's an easy fix- turn it down. If you're drawing enough power to impact the balance of your electrical system then you're listening in the "look at me" range.

The H2's electrical system is a combination of A/C and D/C voltages with most of it being on the D/C side post-alternator. If your stereo is pulling down the line voltage then the balance of the components sharing that system will suffer. The filter caps on the 5v logic side will only tolerate spikes for so long before they fail and take out your module.

You can patch it up with caps and back-up power supplies and it will run, but consider the long term effect on your hearing. I like to listen as much as the next guy, but moderation is the key. Too loud, too long and you'll be sorry.
