where did you ground your amp to? I chose a bolt under the rear door sill, but now my audiobahn sub tube is NOT werking! The amp powerlight is on, buut the light on the remote bass **** is NOT...now the sub will power up , but not produce sound...and it looks like the remote **** is broken...i am going to check ALL wires tonite, but the reason i ask about the grounding spot, is cause for the last month, the scion has been shocking the HELL out of me and the wifey....not sure if the 2 are related in anyway, but just to have an alternative in case that is indeed the issue, id like to hear where u all grounded your ish too. NOTE, this is NOT the 1st amp i have installed, my previous amp installs werked w zero problems....im thinking that perhaps a power or ground wire got rubbed and bared the wire, but, i wont know that for sure till i get home and check! So please post up where u grounded your amps too!

 

grounded mine to the rear seat bracket.....it's holds the backrests of the rear seat to the body....pull the seating part of the rear seat and you should see them....

 

I use the rear seat bracket for my one amp and the front seat bracket for my other amp.

 

yep i used the rear seat bolts
