Why won't my speakers work in warm/hot weather?
I'm using a high level/low level adapter to hook up an amp to the stock headunit which I though was the problem at first so I replaced it but it does the same thing. What would cause it to only work when its cool outside, about 70 and under, but not when its warmer? bad amp? how do I test it? I have a multimeter how do I use it, output frequency?
When it works it sounds great but here in tx we dont get cold weather much

What is the amp running?
Do you know if the HU still has output, is it connected to any speakers?
Have you checked to see if there is power on the amps power and control lead when the speakers run by the amp stop working?
Have you checked the ground on the amp when the speakers stop working.
If the answer is no to any of the last 3 questions, then check and let me know

Re: Why won't my speakers work in warm/hot weather? (fcm)
running 2 audiobahns
the power, ground and remote wires going to the amp seem to be working. amp logo is lit, indicating it has power. (im not absolutely sure but iirc, 9.xvolts at the leads with engine off, maybe it should be higher?). how would i go about testing the ground?

</TD></TR></TABLE> Yes it should be higher, 12V with engine off 13 - 13.5V with motor running and no more then 14.5V with RPM up, and it will vary with load.
Is the 9V on the power wire or the control lead or both?
On some amps the "amp light" is controlled by the control lead and may be an LED that needs very little power.
To test ground set meter to continuity, that's the one that beeps when you touch the probes together, connect one probe to a good ground point, test it by touching other prob to another ground point and see what the reading is, [should read dead short or close to it] a DMM will read 000 with an AMM the meters needle should go all the way up, once you know you have a good ground for the meter check the reading you get when probe is on the amps ground term., it should be the same as your test ground and should not change when you turn on the amp.
