Bose Stereo question -->

Is the amplifier part of the BOSE DIN unit, or is it a separate unit?

Is it possible to insert a graphic equaliser somewhere in the circuit?

Thanks

Re: Bose Stereo question -->

The Bose amp is separate from the head unit, and it located somewhere in the rear side panel near the first aid kit. You can find a diagram on the Italian bose website (www.bose.it). The problem with adding an external EQ (I was thinking about this also) is that there are no Pre-amp outs on the head unit. All outputs are at speaker line level, even to the Bose amp. I think it will be tricky to just simply add an EQ. Also, since the Bose amp has a built in EQ and crossover, the adjustments will not be easy.

I am by no means an expert, but I hope this helps. Email me at rdenglish@hotmail.com if you want to discuss it further, or if you have more questions.

Later,
Ryan

empeg is great, but new products are coming out this summer.

New MP3 players are coming out this summer from all the major car stereo manufacturers. Kenwood, Fosgate, Clarion, etc.... Some use Flash Memory cards and others play CD-R's burned full of MP3 files. Do you use MP3's now?

Have you considered using the First Aid Kit compartment as a place to store stereo components?

All outputs are at speaker line level - Naaaw! are at speaker line level, even to the Bose amp.

Speaker level and line level are 2 different t things.
I'll bet there are line output signals coming from the head unit, that you could create RCA outputs for. Then you could plug in any type amp and sub after that.
You'd have to replace the speakers, but you probably would do that any way.

I intend to take out this power amp, open it up,and trace the inputs and outputs. I'll bet there is a way to relate those input signals to the output lines from the head unit. You could imply add RCA jacks to the wires from the head unit, and power an amp.<p><A HREF="mailto:jbipes@mtn.org"><img SRC="http://pictureposter.audiworld.com/AudiWorldPics/2000/bipecott.gif" BORDER=0 alt="Jeff Bipes"></a>

Be carefull...

There are other options besides line level, and speaker drive. For example, send the signal at speaker voltage, but with only enough drive for a 2,000 ohm load. The noise you pick up between the head unit and the amp will be the same as with line level, (everything else being equal, and it never is) but the noise will be much smaller in relation to the signal.

It occurs to me (but I don't think it is likely) that Bose could use a digital link, or even send the control waveform for a switching amplifier...
