Need Help?

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

No i ran 4 guage all the way and only ground the battery to the frame in the back. Should i run a ground wire from the battery up front?

Run 0 gauge and do the big 3 while you are at it in 0 gauge this will make the biggest difference

big 3 is very important //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Shouldn't the battery of helped though even without zero guage? i mean my amp will go into protect mode even sometimes

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

So your saying that i need to run the zero gauge to see the big difference?

 

[AndrewHD 10+ year member]

Yes, but first make sure your amp is not clipping. If it is then you will almost always see a voltage drop

 

[Brandon9 10+ year member]

how do you check that?

 

[AndrewHD 10+ year member]

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

 

[Brandon9 10+ year member]

Yeah i am using some bass boost and i have the eq on my headunit adjusted. Do you think that could be the problem?

 

[AndrewHD 10+ year member]

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

Ok i will test it out thank you for the help.

No problem let us know how it goes
