Running all grounds back to the battery is one of those "urban legends" for car audio...
It's a lot more work, isn't necessary...and can actually lead to ground loops and "alternator whine" through the speakers when the music is playing.
A good ground spot can usually be found very close to the amp mounting location.
Congrats on the new tunes! I just installed a new set of front door speakers to get myself started....and loads of Dynamat Xtreme in those doors, and some Dynaliner too. HUGE DIFFERENCE in sound quality even with the stock head unit and amp. Can't wait to do the rear doors, amps and more extensive sound deadening everywhere. The LC is a great environment for nice tunes.

and that included both passenger and passenger-rear door speakers, the stock amp under the passenger seat, and the 6 disc changer. By some miracle I got everything dried out great and it all works but definitely shows its 15yr old age plus the added wear-and-tear of being underwater for a good 20 minutes. I am a ways out from doing this renovation - I'm looking at early May right now - but that will come sooner than expected so I have started to piece together the components I want (sourcing via Crutchfield). After doing a lot of research here is what I have put together as of now, I am still on the fence about a few items indicated by the "/".
