Hi guys, hoping someone can help with an issue i'm having. I had a new stereo fitted a month or so ago along with a new active sub. The problem I had initially was that the stereo would only come on if you turned the key to pre-ignition or if the engine is running, as soon as you turn the key back the stereo would switch off (even if you turned to pre-ignition and then back again). So I took it back to halfords where I had it fitted, the guy hooked it up so it was on permanent live which solved the problem (or so I thought).
Anyway, yesterday I thought I'd take the car for a spin, nice day etc. Went to start and just a clicking noise and the lights on the dash going into techno mode! Didn't realise straight away what the issue was, called the AA guy who fitted a battery charger and the car started straight away, so thought might be a batt problem. He asked if I'd left any lights switched on which I hadn't and thats when it clicked, waited for the guy to leave and checked the amp with the engine switched off, key out of ignition, stereo face off as well and the sub was on!! Now I know the stereo is hooked up to permanent live, but shouldnt the amp and sub only come on when the stereo is switched on? I'm taking it back to halfords this evening for them to take a look, what I don't really want is to go back to the old way where it was only coming on with the engine running, any advice would be appreciated. It's a Sony MEX-BT3600U HU and a FLi trap 1000watt active sub.
Thanks in advance
