Why do my speakers cut out ?

Question

My old head unit went out, so I had to buy a new one. I got a pretty inexpensive Panasonic model ($110). But not when I turn my volume up the speakers will cut out for about 1.5 second then come back. I don't think it's the base notes that do it, because I have some songs on my iPod that play fine but have deep base, while other songs with moderate base notes will make the stereo cut out.

Other info: I have a 4 speaker system, but the dash speakers have been replaced with standalone tweeters rather than 3.5in speakers. The doors have 6.25 or 6.5in speakers. There is an amp in the car, I'm not sure what because it was done by the previous owner, I believe it's 200 watts.

With the previous stereo, I was able to turn the volume up fairly high, I never had problems with cut-out sounds and it was loud enough to hear at highway speeds (convertible).

With the new stereo, when I get it up to the level where I can hear it at highway speeds it cuts out. Now I can barely hear it on the highway cuz I have to have it at a lower volume level.

any advice would be awesome

Answer 1

check if the amp cables are loose.

Answer 2

You may not have the correct stable ohm setup for the amp. Most head units accept a 4 ohm stable setup, HOWEVER: the Bose amp installed as a factory option on most cars is somewhere around 2.7-3.7 ohms. If it is an aftermarket amp, I would check to see if it is overheating from having too much current passed through it. Although most bass notes are louder than the highs, they do not require as much amperage.
