Hey guys,
A few day ago, I installed a small class D amp (Pioneer GM-D1400), behind the dash above the glovebox.
Same location as many of you have used before.
First made a fused +12v power lead from the leisure battery (underseat/California) towards dash.
bought a quadlock extension cable, so I could cut speaker wires and make a so called T cable. All connections with crimped connectors.
Speaker output radio goes directly to amp, (high level).
Speaker output amp goes back in the orginal speaker wire loom.
Negative lead taken from an original VW earth bolt behind the carpet in wheel well.
No remote taken from radio, nothing connected to amp (hig level input with auto sense).
It sound amazing with my musway speakers!
BUT
I get random pops from the speakers with radio off.
When taking key out of contact, closing doors, opening the bonnet,...
Sometimes even after a few minutes in the garage.
I monitored the amp. The power ON led goes on for a few seconds and makes a bang trough the speakers. Radio is not powered on.
I thougt I had a remote power issue, so bought a high-low converter. This one produces a remote signal, what I need to run RCA inputs to the amp instead of speakers directly from radio.
Took a +12v in the fuse box center dash with a piggyback fuseholder. Made a negative lead from other chassis bolt than the amp as a test.
Result is exactly the same, altought a tad less loud. This converter goes power on at the same occasions as the amp did.
Even worse: when starting the engine, I just get loud static, louder than the music. Unpossible this way.
This morning did a new attempt, placed the converter in the middle of the van, power and speaker cables totally away from each other.
Had the same results as before...
Somehow a turn on signal is made through interference, most probably to the speaker wires.
Just can't figure out the why or how.
On standard radio, all sounds and behaves fine...
Anyone smarter than me who can figure this out?
I cannot believe the amp and the converter are "broken", both behave the same.
Buying another amp most probably won't solve this.
Can't be a faulty power cable, tried different sources.
The weird thing is, I have another amp for the underseat sub, which behaves perfectly fine. (thank god no popping from this sub)
Takes +12 from same battery, uses underseat earth bolt, high level input through crappy cheap speaker wire...
Unfortunately, it doesn't produce a remote out (no 12v output at remote screw).
