I just had an aftermarket stereo installed in my 2006 Mustang GT. The next day after I got my car back, my battery was completely dead. I charged my battery for 14 hours, took my car back to the shop, and they told me that it checked out ok. Anyone else have this problem?

1-JL Audio 250x1 amp. 1-JL Audio 300x4 amp. 4-5x7 Boston Acoustic speakers. 2-8" JL Audio 8w1's.



Thanks
