Hi,

I have 2 annoying issues with my unit.

1) Ipod and USB volume is very low (CD on 15 is equal to Ipod/USB on 35)

2) Poping and engine noise from RCA (Blown Pico Fuse, Fixed slightly by grounding RCA calbes)

I will be sending the unit into Pioneer however i want to check 2 things.

Do i need to send in the wiring harness/RCA harness. My RCA harness is hard wired to the car, i would prefer it if i didnt have to send it in, the RCA harness has had ground cables soildered to them.

Secondly is it possible to purchase the harness's as spare parts from pioneer or other sources, as i wouldn't mind starting a fresh when the unit is returned.

Finally as i have run some mods on the unit, i am assuming it would be best to return the unit to its default settings?

Responses will be greatly appreciated.

You don't need to send the harnesses and yes, you will need to restore the unit to its non hacked state.

Thanks for the quick reply

Another quick question.

I have eliminated engine noise by grounding my RCA's and turning my Gain down to around 1/8 on the Amp.

When the Gain is at 1/3 engine noise is back.

If i got 2/3 its much louder engine noise.

My question - Will a Ground Loop isolator help this?
