okay so i just installed a 10" pioneer sub into my 03 mini cooper s along with a new stereo and a 250watt amp, everything ran fine for a week and then my battery died, i have no idea why, the pros said that my battery was all good and same for my alternator, any help would be so awesome.

 

see if the remote line is turning off the amp

 

is there a way for me to test that? im really new to all this stuff

 

Check for voltage , Use a meter or trouble light on the remote line

 

alright thanks a ton!
