[QUOTE="CarAudioMk2, post: 8509057, member: 670235"] Hi all, I have a VW Golf (Rabbit in the US) Mk5 with an "RCD510" stereo. Last summer I fitted a [URL="https://www.amazon.co.uk/FLI-FU10-10-22-ACTIVE-ENCLOSURE/dp/B00AN4D4WO/280-6552724-1453232?ie=UTF8&*Version*=1&*entries*=0"]Fli FU10 Active[/URL] sub in my boot (trunk); It's not the most powerful, or the best by any stretch, but I wasn't after blowing people's windows in, or going deaf, I just wanted a little bit of extra bass to my music. I went for this sub as it was cheap and it was small enough to not be too intrusive in my boot. I'd fitted three or four subs and amps in the past so I did this one all myself too. Only this time I had to take the audio from the headunit from a line-out converter due to my stock HU, whereas in the past I've always used aftermarket head units so just used the RCA outputs. Anyway, to cut to the chase... I keep losing power intermittently to the active sub! When I say intermittently, it can happen when the car is stopped, or in motion, and can happen over and over within the space of one song. The little green power light on the amp goes on/off/on/off etc... I've checked the cables are all in tight enough on my sub, and that's not the issue. I've also checked the 12V cable is secured properly to the battery and the EARTH/NEG to an earth point. So now I have the task of finding out what it actually is! My first port of call will be the REM cable, because it's the most fragile wire of all the ones I've run through the car. If it's not that I'm going to have to start over... Questions: 1 - What is the BEST cable to use as REM cable? (you can talk gauges and specs and I probably wouldn't know the difference, so a link would be helpful!) 2 - Is there anything else that is screaming out to you at the minute "WHY HASN'T HE CHECKED THAT?" 3 - If it isn't the REM cable, is there any way I can test the other cables for signal/power without completely rewiring? Thanks a lot! [/QUOTE]
