Hi there. I just purchases an '04 Civic Hybrid, having had a '97 civic ex for 3 years (i loved this car... and now my wife gets it, trading in her '95 civic for the hybrid).

I want to put a new stereo and amp in the civic hybrid. what are the issues that I need to know about? what additional parts will i need to get the stereo into the dash?

specifically with the amp - it's an old Infinity 5 channel amp, 30wx4channels and 100w for the sub channel. I am not planning on running this amp to it's max capacity - i simply want higher quality sound and some low end with a sub.

Will installing this amp in my civic hybrid decrease gas mileage? if so, how much will it go down? what are the gotchas that i need to watch out for when installing the amp in this car? or do i just do it like a normal car - power source from the standard car battery?

FYI - here's my amp: http://www.cardomain.com/item/ALPMRVF357 . I also plan on having the factory keyless entry removed and am going to get a full alarm / keyless entry like my '97 has.

thanks.
