    Service Engine Light???

    I just installed an amp and two 10" subs. The amp and subs work fine, but since I've installed them my service engine light has been coming on. I've listened for any problems while driving, but I can't hear any. The truck feels like it runs fine. Any ideas of why this is happening?
