shahidrazaq Posted May 27, 2012 Report Share Posted May 27, 2012 Hi everyone, Ive just installed the following to improve the dreadful basic sound: 1, vibe 4" components in front doors with tweeters 2, 8" earthquake subs under front seats 3, blaupunkt tha555 amp in the boot with the 5 meter harness Two questions: 1, the harness has + and - connections but I could only find the constant 12v live at the back of the stereo. The wire which said 'ignition 12v' (only come live when ignition is one) doesn't seem to do anything?! 2, where do I get a remote wire from?! I assumed I could use the head units power to power the amp. I connected the 12v constant live and earth to the pnp harnes and plugged in black and yellow plug into power socket on amp. This does power the amp but doesn't turn it off when I turn the car off! After reading online it seems I should power the amp with new heavier gauge (8 gauge) power cable direct from battery and a new earth but where do I get the remote wire to turn the amp on and off? I'm pulling my hair out here, please help?? Thanks in advance! Link to comment Share on other sites More sharing options...
Biscuits Posted May 28, 2012 Report Share Posted May 28, 2012 Hi ya, The wiring harness has everything you need in it, you just don't connect the SUPPLY +12v and ground, use like you said a heavy gauge cable (with fuse) to supply the amp directly from the battery. I assume you've located the amp in the boot like I and everyone else has done in the past, so it's quite easy. HTH and welcome to TSN Link to comment Share on other sites More sharing options...
shahidrazaq Posted May 30, 2012 Author Report Share Posted May 30, 2012 Thanks for your reply. Yes the amp is in the boot and I'm going to add the power direct from the battery (with a fuse!) and earth it to the chassis. The only issue is I still need a remote wire to turn the amp on and off otherwise with a direct live from the battery the amp stays on after I've switched off radio and ignition! Am I correct in thinking I should get a connection from somewhere at the rear fuse box for the remote wire? Finding a wire which is only live when ignition is on? Appreciate your help.

Biscuits Posted May 30, 2012 Report Share Posted May 30, 2012 Am I correct in thinking I should get a connection from somewhere at the rear fuse box for the remote wire? Finding a wire which is only live when ignition is on? The Blaupunkt PnP lead has the trigger if I remember correctly. That or the amp senses the speaker level input is active and switches the amp on automatically... actually thinking about it I'm quite sure this is the case. I definitely didn't have to run a separate trigger line. I remember one of the hardest bits was getting the headunit back in with the PnP lead in place, was a right SoaB ! Although I was doing it in an E92 M3, no a 5er. I'm guessing you've read mine/GizzE's install threads ? Link to comment Share on other sites More sharing options...
shahidrazaq Posted May 30, 2012 Author Report Share Posted May 30, 2012 I did read them yes. Did your amp turn off immediately after turning off the head unit? And tell me about the harness behind the head unit. Almost gave up squashing it all in!!! Link to comment Share on other sites More sharing options...
Biscuits Posted May 30, 2012 Report Share Posted May 30, 2012 It's been a while, but the more I think about it, the amp was triggered on/off from the speaker level output from the headunit, so no it wouldn't have switched off immediately, but after a period of time. The amp also gets BLOODY hot, but this I was informed is normal for that class of amp. Ah.... lifted from page 7 in the manual! So yes, don't worry about the remote switching, it uses the speaker level. I removed the glovebox to get more space/access for the wiring loom to be pulled through. It was the hardest part of the install and yes, I did have to take it out twice to check connections too !!! Link to comment Share on other sites More sharing options...
shahidrazaq Posted May 30, 2012 Author Report Share Posted May 30, 2012 Nice one. I didn't get the manual with mine. Now all I need to do is put in the live and earth and enjoy! Appreciate all the help Link to comment Share on other sites More sharing options...

shahidrazaq Posted May 31, 2012 Author Report Share Posted May 31, 2012 One more quick one: one the manal it says 'as a feature +12v are now available...'. What does this mean? Link to comment Share on other sites More sharing options...
Biscuits Posted June 1, 2012 Report Share Posted June 1, 2012 One more quick one: one the manal it says 'as a feature +12v are now available...'. What does this mean? I think there is now a +12v output on the amp, that you could use to trigger other equipment/amps. (you'll not need it really, unless you want to hook up some blue LEDs that come on/off with the amp Link to comment Share on other sites More sharing options...
Extra300Driver Posted September 10, 2012 Report Share Posted September 10, 2012 Where did you get your amp? I've been looking for a while. Link to comment Share on other sites More sharing options...
