How to get better sound from Bose speakers

Recommended Posts

I have the BOSE speaker system in my 996 tt and the original radio is changed to a Pioneer SPH-DA230DAB player. 


I think the sound is very poor as i seems to lack a bit of fullness. Earlier I had a 996 4S with standard player and speakers and it sounded better in my opinion. 


Is there any amplifier that can be connected or can some thing been done wrong ?

The Bose setup of the 996 is somewhat non-standard: the headunit is connected via speaker-level cables to the Bose amp, which is connected to:

1. front dash speakers (2 Ohm)

2. door woofers (2 Ohm)

3. rear fill-in speakers (2 Ohm, working from a single channel, ie, mono)

4. subwoofer amp, via speaker-level cable.

4.1. the above is then connected via speaker-level cable to the 2 rear subwoofers (2 Ohm, working from a single channel, ie, mono)


Unless you find a much better 2 Ohm amp that is able to replace the Bose amps (which I'm not sure such a thing exists), I don’t see the sound improving significantly from the Bose speakers, they're not very good to start with. When you remove and examine them, they also don't quite look like hifi standards: cardboard cones, shoddy cabling and soldering, small magnets.


My current setup includes a Audiotec-Fisher Match M5DSP amp/processor and a Focal FD 1.350 subwoofer amp in the exact same factory amp positions, feeding Focal speakers, all in the factory locations and with factory grilles:


2 x Utopia Be 13WS as door woofers

2 x Utopia Be 13WS as rear subwoofers

2 x 100KP as dash speakers (bi-amped, which is not the factory case)

2 x 100KP as rear speakers (mono, like the factory)


This allowed me to preserve the factory look and not even the amps are visible.


I used to have a very different setup with huge amps but I got fedup with the looks and the technology nowadays allows for excellent size/sound quality compromises.

99% of car audio speakers are 4 ohm. The Bose system in the 996 is quite odd in that it is 2 ohm.


If you connect 4 ohm speakers to a digital amp only ready for 2 Ohm, it will work, but the speakers will sound tiny and potentially overheat the amp and burn it. I'm sure people have tried that in the past, I haven't so I don't really know what would happen.
