No sound from audio system intermittently

The saga continues. Took it back today and they claim the battery is a problem; it can't supply enough current and the 'spike killed the last amp'. Have given me a loaner battery for a week...

Very dubious as it worked fine half the time, and the new one has the same issue, albeit less often, especially lately in warmer weather. Also still shows an error code on one of the diagnostic screens, although the other screen now says "OK" instead of "NG"... They claimed it would be more probable in cold weather as battery performance is degraded (which is true of batteries). Not sure about the spike killing the amp... if it is the battery I suspect it is a case of the AMP not getting sufficient power when starting the car to detect all the speakers properly... but hard to prove now that I've paid for a new amp.

Will see what the next week brings.

Well, still have the loaner battery two and a bit weeks on and, so far so good. If it was indeed the battery not supplying the correct power at startup to the amp, then I seriously doubt that the original amp was damaged, given that at times it worked perfectly. But proving that will be impossible. I suspect I've been fleeced for $950. Not sure of the condition of the "loaner" battery I have, but they haven't asked for it back - yet.

I'm pretty suspect on everything they said apart from the amp being faulty to be honest, I run dual batts with a combiner (one is a lithium so it always holds the voltage high) and mine has failed the exact same way. Still haven't decided which way I want to go, bloody toyota and their AMP. Makes changing the headunit more complex.
