I tried searching but I couldn't seem to find the answer.

 

Wow, what a noob question from somebody with over 6K posts.

No modification automatically voids your warranty. Now, if your HU dies chances are pretty good that the dealer may claim it was due to your aftermarket amp/sub. If you have an electrical failure or some problem with the HU, speakers, etc. and it's traced back to the amp/sub, those other OEM parts won't be covered.

 

thanx.
