Hi i just bought a kinetic hc800 i added in the trunk. I thought it would help my voltage drops but it is not doing much of anything it seems. Im running about 1400 watts rms and i got a stock alternator. PLEASE help!
Did you run 0 gauge positive and negative runs from the front battery to rear battery? You also should ground the battery in the back again to the frame
It is still starved and a battery will not completely get rid of voltage drop. It has more to do with the efficiency of your wiring. Fix the wiring and you may not even need the battery yet
You need to set your gains correctly with a digital multimeter and test tones, an o-scope or DD-1. Are you using bass boost on the amp or "Loud" on the headunit? Make sure to turn those off also set the eq flat on the headunit
Never use bass boost it only adds distortion to your system in order to make it louder. This puts stress on your electrical and your equipment also. Just set your gains correctly with everything flat you will see a more stable voltage this way
