Hi everyone,
I recently installed a new head unit and active sub and I believe this may be the cause of my flat battery which is less than a year old. I have left the engine running whilst listening to music etc so did not think this was an issue. However after trying to start up my car, once having left it alone for a couple of days it won't start.
Is there a way to prevent this from happening in the future? I've heard of people installing a 'cap'? Are there any other solutions.
Thank you
