wemt with alpine ina-w900bt and alpine components all around...sounds great, BT works well, great having an ipod and the reverse camrea is very clear...

 

That looks great! Where did you find the reverse signal wire for input to your head unit for the reverse camera?

 

Looks nice! Where did you get the install and mounting kit?

 

hey guys...i dont know how they did the reverse signal but sound concepts in bedford ny did the install.

 

Where is the reverse camera mounted? At the license plate?

 

yup it is.

 

about 7 hrs of install time (Alpine head unit, Alpine amplifier, satellite radio, back-up cam). Unit sounds great with the Bose speakers and sub

 

You kept the factory speakers? Do you know how they crossed over the signals? I believe the factory crossovers are internal to the factory amplifier. Did they use an external crossover of some sort, or does the 911 have external crossovers already? (This would be the first car I'd ever heard of with such a setup, if so.)

 

Amp is the Alpine PDX-5 (5 channel amp)...cross over built into the amp I believe.

 

I'll have to check out that amp. To be honest, I've done very little research into the 911's audio setup. In all of the other cars I've owned, each speaker ran on a different channel. For example, if a door had a mid and a tweeter in it, you needed to send two channels to that door. Multiply that by 4, and you'd need 8 channels crossed over. If a car had a woofer, mid, and tweeter, you'd make that 12. The factory head unit normally contains all of these electronic crossovers internally.

Aftermarket speakers come with external crossovers that split the tweeters/mids/woofers, which is why you can drive four corners with four channels. Without crossing over the signal, you will damage all of the components over time. (starting with the woofers)

 

Ok....that makes my head hurt How bout this....sounds good anyway.

 

That's all that matters.

 

I have been looking to update with BT and iPod, and this is one of the units I was looking at. How much was it to install everything. How much more was the rear camera and amp? Is it enough power to overcome a loud exhaust?

850 for the alpine headunit....2800 for everything installed....i have a euroepipe 2 loud and there is plenty of sound from the stereo....

 

Thanks Rad

Hope you have a wonderful Thanksgiving
