First of all i have 2 amps, one 2 channel for speakers, and a mono for the sub.
I bought a new mono and i plugged it in and started playing it to see how it sounds. I drove 200m down the street and then i got massive engine noise from the speakers. I did not touch this amp and it has been working 100% for the past two years!?!?
Funny thing is that all i did was unplug my other mono and plugged in the new one without doing anything to the speaker amp. Both amps have their own runs of power and ground cables. Things in common are the remote wire (which it has to be as far as i know) and the RCAs which are split at the head unit (HU only one preout). I unplugged the mono now, so its the speaker amp running on its own and still engine noise...
It happened last night so il go through and check where the noise is coming from when i get a chance.
Im just asking to see if anyone has any idea as to why and how this happened. Any ideas?
Actually now that you bring that up... I didnt disconnect the battery. When i put in the power wire i got a little spark. But how does this affect the other amp? Also, it worked for a few minutes and it came from nowhere, if the spark did something, wouldnt the noise have come in straight away?
^well that could be ur problem right there - plugging in\out rcas with power on ...possibly damaged something on the hu's circuit board - if u own a pioneer HU they are proned to that ...
Micro fuse right next to RCA junction, notice the white highlight and little plume of blackness on the board.
Gently heat and remove with soldering iron.
Tin a single strand of wire and solder in its place of the fuse.
If this is above and beyond some of you people you can send it to me (for a fee) and I can do it for you, fast and ship it back out via any means you are willing to pay. I'll even test it. Polo..
