eddymon42 Posted July 31, 2015 Share Posted July 31, 2015 Hi all; very simple question! When replacing the Bose amp for an aftermarket one to power a sub, can you use the existing power, ground and turn on leads? Or is it necessary to wire a new power cable to the battery?

Cookie Posted July 31, 2015 Share Posted July 31, 2015 I think you will need to get new cables if you have a fairly powerful amp. The cabling to power the matchbox amp for the bose sub is fairly small gauge from what I remember when I installed my 5-channel amp. Loads of places you can attach a ground cable to if you are installing it behind the seat in the stock position. You can run your remote cable through the centre console to your HU easily enough.

rodgeevans Posted August 1, 2015 Share Posted August 1, 2015 New cables no doubt about it don't use existing ones likely to burn out and could cause a fire Quote Link to comment Share on other sites More sharing options...
iamtheoneneo Posted August 2, 2015 Share Posted August 2, 2015 Yes absolutely new power cabling with fuse . You can run it through with the rest of the front cabling and it will pop down in front of the passenger footwell, thats the easy bit! running all the wiring from the amp is the biggest challenge.

Cookie Posted August 2, 2015 Share Posted August 2, 2015 Best to strip out all the interior panels, centre console and seats for ease. Quote Link to comment Share on other sites More sharing options...
rodgeevans Posted August 2, 2015 Share Posted August 2, 2015 I did some pics of running cable into the doors etc in my build thread. Removed all seats and the trim panels including boot to do my install Quote Link to comment Share on other sites More sharing options...
veilside z Posted August 3, 2015 Share Posted August 3, 2015 Remove passenger seat and the panels behind seats mate. Run all new cables. Quote Link to comment Share on other sites More sharing options...

eddymon42 Posted August 6, 2015 Author Share Posted August 6, 2015 Hi, where can I see those pictures please? After doing a little research - I obviously asked a silly question! I need a much higher rating to run my 500W monoblock amp. I've ordered a 4awg wiring kit with a 120 amp in line fuse. I'm going to run this into a distribution box with a 60amp fuse then going to the amp, again using 4awg cable. The reason for this distro block is I can add another amp and upgrade the stock speakers in the future if I choose to, with minimal effort. I'm also going to use another distro block for grounding - in case I end up with another amp. Is there a good grounding point in here? The amp will be going in the stock amp space and the sub will be under-strut mounted. The amp originally came out of a z and it was done professionally, so it already has a mounting block. Where is the best place to run the cables? I'm thinking of maybe running the power cable down the driver's side and into the sub cavity, and the RCAs down the centre console. I've also seen a guide with both run down the centre console. What do you think? Thanks for your help! Quote Link to comment Share on other sites More sharing options...
Wasso Posted August 6, 2015 Share Posted August 6, 2015 Power is down my passenger side and audio signal down the Central tunnel. The battery is on the passenger side and so it makes logical sense to run it down that side. Quote Link to comment Share on other sites More sharing options...
eddymon42 Posted August 8, 2015 Author Share Posted August 8, 2015 Great, thanks for the tip. I guess it then goes under the panels behind the passenger seat and into the sub cavity quite easily? I guess there is a good grounding point in the sub cavity too? All I need to is pick a stereo now! Thinking of thePioneer AVH3700DAB Quote Link to comment Share on other sites More sharing options...
rodgeevans Posted August 8, 2015 Share Posted August 8, 2015 Don't run power and rca together can cause interference best doing power down passenger side and rca through centre Quote Link to comment Share on other sites More sharing options...
eddymon42 Posted August 8, 2015 Author Share Posted August 8, 2015 One more question!! I am going to fit a DAB radio bu I have read that the 350z has an amplified antenna which means I can't use a DAB splitter. Is there any other way without having a seperate antenna on display. Would a DAB antenna work inside the dash plastic, just like a GPS antenna? Quote Link to comment Share on other sites More sharing options...
