I have a 2002 with the BOSE analog system with the BOSE subwoofer. I removed the factory headunit and had a 2011 Pioneer X930BT Nav/audio double din unit installed running the factory speakers through the factory BOSE amp in the trunk. I am in the process of removing the Bose subwoofer from the car and would like to remove the factory amp also and just use the Pioneer built in head unit amp to run the factory speakers. Does anyone know if that is possible? Thanks....

 

Yes and no. Trying to adapt parts of the Bose system to an aftermarket systems is a losing proposition (it costs more than it is worth with lower quality sound). Junking the all of the Bose system is the way to go (head unit, amp, all the speakers etc). You can find aftermarket speakers and subwoofers that will fit into all the factory locations including the subwoofer box in the back. However the Pioneer head unit(which is a really nice unit) doesn't have the built in power or crossovers to properly drive the all new speakers. I would suggest you do some research with your installer on an amp(s) that will provide the needed power and crossovers to obtain optimal sound for your money.

 

I did something similar. I am running the Pioneer head unit. I replaced the dash speakers with Hybrid Technology drivers and kept the other Bose speakers, including the sub. Everything is driven by two amps: a JL Audio 5 channel amp for the dash, doors and sub, and the rear fill speakers are driven by a 2 channel Kenwood amp. I recognize better sound is possible with switching out all the speakers, but this system is very good. It is important to adjust the crossover points for optimum quality. I had a limited budget, and this installation works very well. I have a very nice tube system at home, so I am spoiled with regard to sound. Car systems are all about compromise. I would also suggest that the 911 is not the car in which to put a high-dollar system. There is simply too much low-frequency noise from the tires, engine and wind (if the car is driven properly) for a good sonic environment.

 

Thanks for the replies guys. I guess I should have made myself more clear. I do not intend to replace the subwoofer with a better unit. I am just removing it. I do not care about sound quality as this is predominantly a track car for me and I just want to get rid of the dead weight by dumping the sub and the amp as I figure the Pioneer headunit amp would have enough juice to run the remaining speakers. The GT2/3 does not have a sub or an amp either. It's not about sound quality for me as these cars make a horrible listening environment anyway. I just want a radio to listen to on the way to the track....

 

I replaced my window regulator a little while back and, as one of the steps, had to remove the door speaker unit--I was shocked how bulky and heavy the thing was . You'd definitely shed some good weight ditching the sub, the amp and at least the two in-door speakers. I don't know what kind of speakers are in the rest of the car (the dash and the rear), but perhaps the Pioneer would have enough juice to run those speakers if you take the behemoths in the doors out of the equation?

 

I've thought about the speakers which come in at about 5lbs each for the fronts but I still want some sound thus I just want to get rid of the sub and amp.

 

I removed my factory amp when I installed a Z120BT head unit. The head unit puts out about 40 watts per channel when used without and amp and it did work quite well compared to my non-Bose system. I added an Alpine PDX5 a little later and it made a world of difference in sound quality, but if you don't care about the quality - your head unit alone will work.

 

Great info. I just didn't know if the Bose speakers were some oddball impedance that would not be compatible with the Pioneer headunit amp which I think is 30watt x 4. Sounds like it will work. Thx....
