hey, i just got a 12jlw3v2. got a cheap visonik 400 x1 2 ohm mono amp. its all wired at 2 ohm. turn it on theres pop noises also when turning off. and the amp is so hot that u cant hold ur hand there for 5 seconds(is it normal). and the amp will shut off if i turn the volume over 20. the amp gain is half way so is the hrtz.
