Question Audio questions (Bose)

Hello all,

I have a 2003 ML500 and I have a BOSE Sub under the driver's seat (that doesn't work), but I don't see a BOSE AMP under the driver's side dash.

It's probably important to note that when I pull the radio/Nav unit out, there are coax and optical cables that aren't hooked up to anything (nor are there any places to connect them to the HU).

Am I missing something?

If my memory serves me correctly (sold the ML in ‘14), you are missing at least a Bose amp to drive the sub. But I don’t think it was under the dash. What I remember is an amp under the dash to drive the door and dash speakers, and a big amp with cooling fins bolted to the floor under one of the seats to drive the sub.

I've noticed that there is no Bose amp under the dash and it appears that someone did the Bose delete.

Your only alternative may be to go with a new after market setup unless you can find the used components on eBay. I don't know why people didn't like the Bose system, but many destroyed the original setup for what was basically an inferior system. I am pretty sure the original components are no longer available new.

Agreed. I'll be putting an aftermarket DD and speakers in it eventually.

Thanks,

Exactly. Why someone would do that is beyond me.
