I understand that they will work perfect with each other but the real question is will it realy steal from my alty and battery oe even worse can it harm it?

Well thanks and if you need the model number here they are.

sub :

amp:
Kicker 06ZX200.2

Car: 2002 honda accord I4 vtec

 

you will be fine with that amp. Its better to be overpowered then under IMO. but 50 watts is no big deal. First because you will not be booming that hard to were it will be a major factor, Second music is dynamic, third because the amp is not going to be rms 200 watts all the time.

 

thanks alot you have saved me alot of aggrevation and research.
