I have a 98 Max with the Bose speakers and Bose head unit. I want to change the head unit to the Sony Xplod ES CDX-M750, but keep the bose speakers. Is this possible? Next, I want to add the MTX Road Thunder RT 2600 amp(300 watts x 2 at 2 ohms) to power 2 MTX Thunder 6000 T6108 subs (10" 8-ohm 250watts RMS). Is this possible? Will heard that it will mess something up with the Bose speakers in, or something like that. I need suggestions, help, and anything else to help me install a tight thumpin system.

 

I own a third gen w/bose and just bought a Sony Xplod CDX-L550X. I guess when dealing with bose audio, it doesnt matter what year car you drive because our concern is the speaker amplification. The bose speakers are individually amplified. So you will have to buy what they call a premium wire harness which has some sort of "volume adjuster" built in. What happens when you install the radio w/o the premium wire harness (like I did, no harness) is that the speakers will be louder than the radio sets them to be. You can turn the volume on the HU to be medium, but the speakers will be maxed out. In my case, one notch on the volume know will have the speakers loud enough to please anyone. The sound quality isnt all too great either.

So my advice is, get the premium wire harness.

The answer to question... YES ...you can use the radio on the Bose system.

I never got why everyone said you need the Bose "Line Adapted" to use an aftermarket HU. No, an aftermarket HU will not run the Bose speakers w/o the built-in amp with their low impedience (measured 1.7 Ohm). But the amp is what sees the speaker load, not the HU. Yes the volume will be louder, just don't crank it and you won't blow the speaker. I would normally listen to my Denon at a volume level of 15-25, but with the Bose amplfied speakers it's more like 5-9. As far as I can tell, all that the adapters are is a series of potentiometer (dimmer if you will) that reduce the amplitude? of the HU's signal.

The built in equiliztion for the Bose HU throws the EQ curve off a bit for an aftermarket HU, but not too bad IMHO. This setup will certainly do until I can afford decent speakers and an amp.
