Genuine radio
Got a standard factory 92 240 radio and the left side speakers are less powerful than the right, if you have the balance set in the middle hardly any sound comes out of the left speakers, same whether all on fronts or all on backs, so clearly a L R issue. You can adjust the balance way over L and get even sound. What do I look for? I believe it’s going to have an amp down low in the bottom cubbyhole?

If it only affects the cassette player it could be the playback head alignment, or possibly a fault with the tape transport mechanism. If you have the amplifier fitted behind the lower cubby hole, the depth of the recess will be noticeably shortened. I think that type of amp uses the bulkhead as a heatsink.. but from memory it only drives the rear speakers (the radio has an internal amp which drives the fromt speakers), so if you have that setup and the problem is front and rear it points to the pre-amp stage, like the volume or balance control. |

It’s a td-603 from a 92 model. It has got the amplifier, but haven’t got that bit out to investigate if any of those wires are tampered with. It has separate rear door tweeters. It was the same on radio and tape, however now no sound comes from the tape, it was a bit crackley when I first used it and now as I say tape doesn’t play. As for L R I think it’s the same weather all on the back or all on the front, but I will check when back, I’m away until Wednesday. I have a 89 car, I was going to take the radio out and try, that has a separate amp, but the connectors are different at the top, dose the car harness run to the amp and the amp to radio connection come from the amp, and if so are the amp connections the same so I could change it all, or is top and bottom connections all intergrated in the car? In other words if I took it all from the other car would it be plug and play, the other car only has standard rear speakers though, no separate tweeters. Or should I look for another TD-603? |

So I think you will find the connectors, the amp and head unit will not swap individually between the cars. As for finding another TD 603, I'd think only if it was really cheap or you wanted to retain the original equipment – there were places that repaired them in the past, but they are now over 25 years old. Modern replacement units can be had with built in amps so you can connect directly to the speakers using a bypass wiring harness, but I am not sure where you will find the amplifier, someone else will know. |

I do wonder if I could swap the entire 89 set up or if the wires in the car will be different, I will have to investigate further unless someone knows! Perhaps I will see if I can get mine repaired! Not sure where to look though, everything now days is throw away!! |

I replaced my worn out speakers with some 4" JBL's ...
about £14.00 a pair I think. Fitted in perfectly and then put the old original speaker covers back on. |
