Hey there,
Well, I don't know if im putting this into the right thread but here it goes.
I ran into a problem one day and all of a sudden the head unit (along with the clock, and cigarette input) turned off. I check the fuses and none were blown. Then, 3 months later I hit a curve and got a flat tire then out of nowhere I got the electricity flowing back again.

The real problem is, the subwoofer, front right side speaker, and the front right side tweeter works. And the sub, speaker, and tweeter on the left side of my car doesn't. I was just wondering, should I replace it and buy a new pair of speakers? since they're old.
Also, I was wondering if anyone knows what size are the front speakers on the doors.
Finally a day ago, i took my head unit out and the external amp connecting to it out and found that the head unit is from a 1993 camry and the external amp is from a 1994 4runner. Is that normal?
