I have a small amplified subwoofer and would like to place it in the trunk of my C-230. Can I pick up signal from one of the rear speakers? I've been told I might need a high to low filter or a crossover unit? Could the fact that I'm feeding an already amplified signal to my subs' amplifier create a problem?

My rear deck speakers seem to made of several separate speakers, perhaps with their own crossovers. There are what appears to be two small woofers, pointing down into the trunk. Should I splice into their input?

Thanks,
Glenn

I don't know about any hi/low filters, but maybe they are required, I can check it mine has that if you want to know for sure. I am talking about my C280 also.

But to answer your question, yes you can splice into the rear speaker for a sub. My sub gets it's sound from the driver's side rear deck lid speaker. Have never had any problems, so I don't see why you couldn't.

Does your sub come with a built in crossover? Many crossovers do.

I have two subs. One is in a premade box with a crossover unit and is a 100W, 8 inch unit. To get any bass through from the trunk I may need to use my old 12 inch crunch and 200W amp. I don't have a crossover with this.

Can I run what is in effect already an amplified signal from the rear speakers into my sub's amp, or is this too much power?

If it is designed to work with speaker level signals, no problem. If it expects to see a line level signal you need to attenuate this signal with a resistive network. This will convert speaker level to line level signals. Such a device should be available commercially, either at a local car audio shop or at a place like Crutchfield, http://www.crutchfield.com
