Hi there,
The 07 Civics have the radio integrated into the dash pretty nicely. I wish to add an amplifier, upgrade the speakers and install a sub but don't know if the stock radio is pre-wired for amplifier outputs and such. Pleaseadvise if anyone has experience with upgrading the stock radio or if there is an aftermarket head unit that can fit the dash without many modifications.

Thanks,

 

The stock radio has NO provisions for low level outputs. You will need a hi to low. OR replace the deck.
Heres the dash kit and instructions for installing it. It's not as hard as it looks.
