Car would not start because of amp

[vsolara]

I've been running my type R/alpine mrp-m500 (4 guage wire) for about two months now without any problem except some light dimming at night. Yesterday as I was driving my headunit started to turn off for a second and turn back on a few times. This was the first time this has ever happened so I figured it was the heat. However, today I was able to unlock my car with the key fob, but when I turned the key the car went completely dead (no power to anything). I disconnected the amp from the battery and thankfully the car turned on without a problem. Why is this happening to my car? I got off lucky I was able to get my car running again, should I just sell my system?

Try checking the battery terminals sounds like they may be dirty.

Yes! Get rid if everything! Your car is screwed!
