Well, I am very sad and disappointed to find out that due to the 12v battery being a lithium battery integrated with the hybrid battery system, with no terminals, that I quite likely cannot install an amp and sub. My audio guy says that it is theoretically possible to wire a low power amp to the ignition wire which is rated for 60A, but he doesn't want to be the first one to try it. Any ideas as to how one would be able to set up an amplifier in this damn new and unique car? I'm pretty angry at myself for not being aware of the limitations of this before my purchase. I need my bass. Thank you!
