[QUOTE="Jeffdachef, post: 8677309, member: 650438"] its definitely amplifier/wiring/electrical related. Need to do further troubleshooting like if you have a different amplifier. It is a hifonics which is pretty much overpriced power acoustik so reliability and actual performance is next to nothing but again too early to say without troubleshooting. Its not a failing alternator if it was, your amp would shut down and you'll have even more system dimming, voltage drops. The fact that you arent pulling as much current as before means your actual power output from the amp dropped somehow. Did you actually take out each sub and test each pair of voice coils to see the actual impedance rating? You might have a bad coil somewhere. Did you actually measure voltage drops of the car while playing? [/QUOTE]
