[QUOTE="Jepalan, post: 8249751, member: 655519"] You've only got a 300W amp, so stock electrical *should* be able to handle the load - might be something else wrong. I agree with the other posters and would do these things: 1) Have your alternator & charging system checked out 2) Make sure all head unit and/or processor settings have been re-tuned to where you had them before the batt swap 3) Using a voltmeter look for drops in your system - check at battery and at amp input - check often. 4) Double check the integrity of amp power/ground and battery connections and wiring. 5) Double check fuses and make sure one hasn't partially failed (it happens - ohm them out, or look for voltage drop across fuse under power) And regarding the illumination - do you have power/ground connected to the other terminal posts on the sub enclosure?
