mckenziecz, the capacitor is wired to the amp because the live wire is connect to the capacitor and then the wire runs to the amp. and i have the amp grounded and the capacitor grounded in different places. a capacitor looks like a tube which has digital display on how much volts you are getting, atm i am getting a steady 12.8 12.9 which is correct from my research but i have checked everything over and everything seems to be okay
i rang the person that sold it to me an he is going to meet me tonight to have a quick look through because he says that i might have wired it wrong.
Fault finding definitely needed. I would check the following;
Check head unit remote wire with a voltmeter to check +12v output.
Check amp remote function by briefly bridging the +12v amp supply to the remote input.
The above will rule out or confirm both a faulty head unit and amp remote trigger.
With regard to the capacitor, if you are showing voltage then in principle it seems to at least be connected between supply and ground. Regarding the wiring, the +12v supply will be in-line between the +12v supply and amp +12v input.
Wire trace will be: +12v battery supply engine bay -> fuse -> capacitor +'ive distribution block in boot -> short +12v jumper to +12v amp supply.
Both amp and capacitor have separate grounds.
I've seen people wire these things up all sorts of ways....
