Hello,

When I hold down the SRC/Off button to turn off the music in my recently installed U310BT, I hear static/fuzz from the speakers

It is not loud static, but noticeable when the cars engine is not running

Does anyone know how to make the static stop?

Thanks!

 

What other components are in your audio system?

PAC ROEM-NIS2?
Factory bose amp?
Aftermarket amp?

 

Factory Bose Amp

 

What harness was used? PAC ROEM-NIS2? 70-7551? 70-7550?

 

I am unsure - I had it installed at BestBuy - they used one of their harnesses

 

If the problem has existed since the install, take it back and make them fix it.

It's entirely possible they hooked the amp turn-on wire to the accessory wire instead of the remote power wire.

Then again, it's best buy, so they could have done lots of things wrong. You paid them to do it right, make them fix it, or demand the money for the labor refunded so you can have somebody else fix it.

 

the problem has existed since install - I will go back to them

 

BestBuy's explanation:

Because the U310BT Amp is connected to the second Bose Amp, there will always be a small amount of feedback - Bestbuy will be no help

What can I do myself to fix the issue? Should I go in and find out what harness they used, and if it is connected to the accessory instead of the remote power?

Im assuming this threat is the best possible resource for this: https://g35driver.com/forums/audio-v...urce-list.html

 

They had used the 70-7550 harness - I replaced myself with the 70-7551

It fixed the static problem! however, now when the engine is running, there is a faint squeal - when the car is on, but the engine is not running, there is no squeal

Thoughts on what I did wrong?

I have all the grounds connecting at a single point (both 70-7551 grounds, ground from HU, ground from Metra Axxess ASWC, and a black and green wire coming from the car - bestbuy did this) - they are grounded to the screw underneath the clock...

I disconnected the black and green wire - the steering wheel controls stopped working when i did, however the faint squeal remained when the engine was running- when i reconnected the wire, the steering wheel controls came back, and the faint squeal remained

Metra tech support suggested getting "ground loop isolators"

Thanks

 

the "ground loop isolators" worked

now everything is perfect, except the bluetooth volume is really low?

 

The volume from other people? or people can't hear you?

If it's people not hearing you, where is the mic placed?

If it's the volume of other people, and you're running android, check for a program called "DSP manager"

 

It's the volume from other people that is the problem

I have experienced the problem on both my personal android phone (huawei u8350), and my work blackberry (bold 9900)

I will download a "DSP manager app" and see what happens
