G'day,
I know this has been talked about before but i decided to start a new one as to get a more personal responce etc.
Today I replaced my alpine amp with a more powerful 4 channel soundstream amp.
Changes were as follows:
extra RCAs from head unit.
new speaker cables, from rear speakers to amp
All the other wiring was the same.... (i think) and the alpine amp was just running the sub.
Now with the new setup when the car is running there is a horrible buzz, which increases tone as the rpm increases... (as a guess i think it could be in time with the spark plugs). This buzz can be heard through both the rear speakers and the sub.
When the car is not running there is a soft buzz which stops when i put the face down on my pioneer 7750mp. (the headunit stays on so you can put in a cd)
With the previous setup there wasn't any off these noises. I guess the next step is to put the alpine back and check to see if the buzz remains....
I don't think the problem is grounding, as there was never a problem with the old setup.
I read in one of the threads here that if speaker wires or rcas are touched together when the system is running, it can blow a tiny fuse inside the pioneer head unit. Is this possible? (it is quite likely that something was touched together today...)
Any other suggestions?
Thanks
Rohan
