Picking up this old thread - I cant seem to work this out either, did anyone manage it?
I thought you either had the bose or the second battery not both? I' have bose and have assumed I dont have the other battery. My car is a 2009 GTS. Anyone confirm before I rip the bose out?
Hi yes, Well after 18months and a lot of miles I can share a few thoughts. Firstly. I've done a lot of offroading in the car. As a result I've picked up or had cuts / splits on 2 of the tyres. This caused me to replace all 4 tyres recently as I was worried about impact during long trips. So I put 4 more BFGs KO2s back one. Immediately after that I 've 1 tyre delaminate following 90mins at 160kph. Not impressed. Tyre has been replaced under warranty, but not sure yet whether the tyre or batch is an issue. Whilst I've never had a BFG actually puncture, I have to say, they are expensive, and they are heavy. Also the on road performance is pretty average, clearly its an AT tyre so you should be prepared. Stopping distances are way longer than street tyres. I"m about to do a 2000km trip, including 220km desert crossing, so lots off road, which will bed the new tyres in one way or the other. But I've lost a bit of faith with BFGs. I'm now 50:50 on whether they are worth the money and the weight penalty. That said, there has been pretty much zero rubbing, and I've even managed to drive the car with the air suspension collapsed. Not far, but it was OK. This was one of the criteria for me, due to the sometimes remote locations we go to. Hope that helps and is a balanced view.
As it happens I've fitted a Motor sports kill switch to my cayenne. Mine is a 2008 GTS, and has the 17" spare and bose subwoofer. However, I needed a kill switch fitted. So I've fitted mine to the base of the drivers seat. I would figure on a car with dual batteries, there is no reason why you couldnt do the same. Out of interest, I'm keen to take the bose out and fit a second battery under the wheel. Not worked out details yet.
OK - fixed this one myself - for reference for others. It looks like its an issue with the FO connectors, if they drop signal, the unit doesnt seem to show power. Once this is resolved, all is good.
thanks guys - sorry to doubt - just dont want to get it wrong. OK - I'm good to go, can turn of airbags at will . Going to try on my next sand trip in a couple of weeks. Will report back.
Well, its early days, but here is what I can share......I had an SUV, now I have a truck :-). The ride is ruined, its a lot harsher than the road tyres. There is a whine, although not too bad. The car is fine up to about 140kph (not been any faster), and around town you dont notice the difference in noise. Out of town, its a bit of worse, but really OK. Will report back when done a decent long trip. As expected its a trade off, the fear of punctures on trails was too great. having had both old and new tyres side by side when not mounted. the difference in flex is huge. Will report back on sand performance once I've had a chance. I've gone quite aggressive, lets see if that pays off in the long run.
OK - folks, I've done some research and checked my car in detail. It looks like disconnecting the battery and removing this box above (or disconnecting it) is the way forward. It looks like my PCM2.1 doesnt need a code so I should be able to disconnect battery without fear. Further research indicated that actually there is a roll over activation built into the airbag system. Hence the need to do this.
Hi - thanks for the suggestion, I need to disconnect the Airbag module, so I need the system to be powered down. that would be easier otherwise, and what the installer did, last time the battery was changed.
Hi, I need to disconnect the battery, before I do, I dont have the radio code. From a little research I have the PCM 2.1 in my GTS. I think to get the code, I have to call the OPC, but need the serial number of the unit.......can I get this without pulling the unit on the car? Would like to avoid pulling the unit if possible.
OK guys, looks like the only safe way I can work out is to remove the module, whilst off road. This involves disconnecting the battery, which means I need the radio code....going to put another thread up for that. Will then report back. Going to need a quick way to do this, if tis going to be a regular thing. thinking of fitting a cut out switch to the battery.
