I've looked around and cant really locate to much info anywhere on this.

Im looking to install my to 10'' Alpine Type R subs in my H3. I'm not in the market to upgrade my Stock Navigation system. What adapters will i need to get, and where is the best place to get them? With the adapters does it by-pass the factory Monsoon sub?

Thanks for any input. Im use to installing systems in trucks and after upgrading to this dont want to lose the amp to the other speakers.

Thanks,
Chris
