Hey guys just got a new system installed.

Infinity Kappa Speakers front and rear as well as an Infinity Kppa 10 sub, and Kappa FIVE full system amp.

Just picked up the car.

There is an extremely loud buzz.hiss coming from the speakers and seems to get worse as i accelerate the car. Sound goes away when head unit is turned off.

Another issue. It seems I lost all my mids. Im assuming theres a way of setting up all that through the head unit but there are a million settings and i dont know which to use.

PS. Im running a Pioneer AVH-P4100 Head Unit

PLEASE HELP!! Thank in advance.

 

Congrats on your install..

I am not a car audio expert, but I think you probably need better grounding of your components.

I hope wrathernaut and eggyhustles chime in.

 

It is a poor grounding issue.

 

Ground

 

Just take it back to the shop and let them know. They took care of the noise for me

 

let the shop faint the problem.

 

I'd be weary of any shop that left a car with whine like that.

Was this a friend who had installed a sub in his car as his only experience, perhaps?

There's way too many things at this point that could be the problem

Could be a bad ground, or could be waaaay too small gauge wire used as well, with an install apparently as bad as you got I'm not ruling anything out.

I'd say take it somewhere reputable if a friend did it, or make the shop do what you payed them to do, if you had it done by a shop.

 

i had a local shop do it. i will be taking it back to fix the issue.

are there multiple ground locations? anything thats a quick fix?

also do you guys recommend certain EQ settings to get my levels just right. seems like my highs are too high and mids are way too low.

thank you so much for the help guys. much appreciated.

 

One other item to check is if they wired the audio signal cables and the power on the same side. That will cause whine. They should have the power cables (assume at LEAST 4 gauge, if they did 8 you will have trouble) on the passenger side and the audio on the right side.

Otherwise its a grounding issue.

As far as tuning, just play with it until you like it, i have played with mine for 6 months and almost have it dialed in, the one they gave me at my install shop wasnt right for me, i like more bass and lots of treble with lower mids.

 

they probably ran the audo wire and power wires on the same place, to save some time.

 

If you have audible whine at an inch of separation, you'll have the same whine with 2 feet of separation. If you have to separate your signal that far, you've got wiring problems that if you just ignore and treat the symptom by moving wires further apart, you're doing damage to your entire system instead of treating the cause - bad ground, bad power or a poor connection elsewhere in the system.

4 gauge minimum, yes.

 

hey guys heres a pic of the amp settings. anything i should change or adjust?

 

take that to a pro to be tuned

You have the gain jacked up all the way smh

And you're low passing the sub @ 32 hz when it should be low passed @ 80hz

 

you guys le me know and i can adjust the levels. since the guy installing my stuff doesnt know what hes doing i dont know who else to take it to.

 

Here's where I'd start with that amp.
LPF 80hz.
Rear and Front at FULL.
All gains set to min until you do basic setting of proper levels.
Boost on sub channel to 0dB
HP on sub channel to 80hz
