I have a Kenwood CD multichanger.
This has only just started happening (i think) If i have the volume up loud (vol goes from 0-40 - above 29) after a couple of minutes the vol level starts to drop off and distort (slight distortion) - i have to decrease the volume below about 20 then it picks back up again. this no3w happens each and every time. Any advice gratefully recieved Thanks Paul |
Your internal amp is getting too hot and throttling back the output.
Are you by any chance running two speakers off one set of outputs? Solution: use an external amplifier. Even a low powered one (such as alpine 3522s 2x35W for about 70 quid) will be so much more effective. Despite being a "lower" power rating, it is about the size of a head unit, has a significant heat sink, etc... Makes you wonder on how they can fit the same amount of electronics needed to make a decent signal into a head unit. Or can they ;) Nick. |
Thanks for the reply
The head unit is 4 x 40 watts per channel I used the existing wiring as supplied within the car so i believe only one speaker per channel is connected The speakers are 3-way Sony(ft)/Kenwood(r) units rated at 80 watts per channel I know the head unit has pre-outs so perhaps an external amp is the answer.

Don't believe the power output from the head unit - it doesn't mean anything. Well, it might, but nothing useful. The 2x35w of an external amp is wayyyy more than 4x40w of an internal. I'd go with Nick's suggestion!
