Hey guys,
I wanted to add an aftermarket amp to power only a 10" sub that I have. I read the FAQ on upgrading the entire system on a premium HU but what about only adding a amp and sub?
Can I just use a HI/Low and 8G amp kit from HU to the trunk and be good or do I have to do anything to the stock amp in the trunk also?

There's a sticky for that:

Just run your own power from the battery to the trunk and tap the signal wires coming from the bose amp.
