i just got my JL 500/1 today hooked the whole thing up and had a problem... it wouldnt turn on, so i reset the power from the battery and it would turn on and stay on for a little bit if i turned the car on had music going, but then it would just turn off again and in order to make it power up again i have to reset the power...... Im using the signal sensing mode, and with the remote it did the same thing, just turning off after a little bit.... any way to fix this?
