Sub, amp, wiring problem

[R8EVS]

Hi guys, new here!

 

Just purchased a US spec 2004 350z roadster, i believe it has the bose sound system in it as it has a bose sub behind the drivers seat, however headunit has been upgraded to a touchscreen sony jobbie!

 

I have a problem that the sub does not work all the time, it cuts in and out whenever it wants too. However only stays working for 10 seconds or so before cutting out, seems to only cut in when going over a bump! All other speakers remain working.

 

I have taken the sub out and checked the wiring connection to it but no noticable problem there. Was thinking it may be the wiring to the amp or headunit.

 

Asked my local ICE workshop, they said the problem was the aftermarket headunit won't work with the sub. However I live in Dubai and don't trust them as think they just want to get a new amp and sub + install out of me!

 

Questions?

 

What is the problem and is it easily fixed?

Is their an amp and where is it located?

What would be the cheapest solution to get this sorted so I have some bass from the sub?

 

Thanks for your help.

there are 2 amps , one in the boot drivers side corner and the one for the sub is the compartment wiht the sub attached to the plate. you mihgt want to check around see if these have been changed or the wireing re done.

Thanks, i will have a look to try and find amps later, wiring didn't look changed when I looked last time.

 

Should all speakers, amps and subs be working tigether and well if just a headunit change?

yes , most myself included still have the bose speakers and amp in place although i have an alpine amp for my sub.
