Message: <blockquote data-quote="stay_high" data-source="post: 8311312" data-attributes="member: 633837">I have a Fi Q running off a mb quart onx 1500.1 and a set of ID components on a small amp for the front. The past couple weeks the sub has been acting strange. It started to stop playing every once in awile and gradually started working less and less over the past week. Finally had time to look at it today. I turn on the car and of course it wants to work.. I play it for about 10 minutes at all different volume levels with no problems. then about 15 mins in it cuts out. i go back and check and No loose connections on the amp/speaker wire. The amp was still on when the sub wasnt playing which led me to believe it might be bad RCAS. I tried a different set of RCA's and it still didnt play. I then tried using an RCA to headphone jack and running it straight to my iphone to see if my headunit was having issues. Still not playing. The only thing i noticed upon turning the car on and off is that, the little green power light on the side of the amp will sometimes turn on and sometimes wont. Sometimes it will light up brighter than other times. But the "mb quart" lettering is always lit up. The protect light never turns on so the amp isnt in protect.and it will work at the random times. Like it wont play for a few days then it might work and sound normal for 5 minutes then just goes out again. Regardless of the volume I play it at. The amp always stays and never goes into protect so its not a bad power/ground/remote connection or anything. The only thing I have left to try is to rewire the sub and see if its the speaker wire that's bad I guess? I could also try a different amp if I can find a friend with one...I know its kind of hard for anyone to say what could be wrong with it based off this but.. any suggestions?</blockquote>
