Rear Bass Speakers Not Working !

[stueyg]

Guys,

I've had a search for this but can't find the answer.

I have recently bought a 2001 IS200 Sport.

Neither of the rear bass speakers work, the higher frequency ones do. The cables to the speaker in the boot are attached and don't appear to have been interfered with.

From what I can make out the bass and higher frequency speakers are powered and fed seperately.... so far so good.

I popped into a ICE shop who did a quick check on the bass apeakers and they made a nice hum, so I'm assuming the speakers themselves are OK.

Question is any thoughts on why the bass speakers are not being fed. If so where is the problem likely to lie ? I have seen some talk of there being a crossover in the rear behind the seat, some talk of it being within the amp( behind the glove box). Speaking to various so called experts at ICE places non of them really seem to have a clue about the set up in this car. Ideally I'd like a bit of knowledge to check myself first or to ensure that they are not going off on the wrong track. One was talking about the problem being in the head unit but that doesn't make much sense to me.

The head unit is original. As i say there is music from the higher frequency speakers in the rear but no bass. I understand there is seperate wiring to the higher frequency speakers.

Thanks in advance for your help !

There is no need to post exactly the same topic twice... have a look at the other topic u made for replies

Sorry, on reflection I thought that maybe there'd be peeps that were into audio that would be here rather than in the other forum.
