Just in the process of pulling out the std. Philips head and CD Changer to replace it with my Alpine stuff (UK MY99).

Two questions...

1) There is what looks to be an extra earth lead that attaches to the back of the Philips head unit. I can't see anywhere on the Alpine to attach it too - is it just a Philips specfic thing or does it do something important?

2) The Alpine manual recommends pulling the -tive connector off the battery before plugging it in. Will this screw up the alarm / immob? (Std. Subaru UK fit).

TIA,

ChrisB.

 

I had to make a similar post in January whilst putting my CD player in. Those in the know said to just tape up the extra lead and forget about it, so I did no prob's. Still not sure what it was though. The alarm has its own battery back up so should be OK.

 

Re:2 - everything says this. I have never bothered, and have yet to blow anything up.

It's one of those "cover your ***" type statements that I ignore, partly as I believe the "shock" of reconnecting the ground in a less than perfect way is potentially damaging for sensitive components, such as alarm/ecu etc....

I'd ignore it, but it's at your risk, etc.

 

Cheers guys.

I ignored both and I'm still here!

Only problem now is the Alpine stuff makes the speakers sound even worse. Best get those Infinitys sorted out I think!

Thanks again,

ChrisB.

 

You'll need an amp M8 before your finished

I might just have the very thing...

Hmm, I don't suppose you know somebody selling something do you?

Nick,I'm shocked.I know you know what you're doing.I know I know what I'm doing.But those instructions are for the novice,and some really bad things can happen during install if the power is live.
I must say that I don't bother either because I know exactly what's what in there.But if you're not so sure,by all means,do unhook the negative terminal until you know things are right.
I've made many mistakes in the past and this was one of them.Play it safe.

Yep, I know. But! Could worse things happen by someone clumsily messing with the battery terminals, sparking them out thus frying their alarm (clifford alarms really don't like non-smooth powerups) or ecu?

Or by leaving the spanner that they were working with near terminals. I've seen a spanner melted by shorting across battery terminals...

Good advice. The instruction is there for a reason: to stop you doing something stupid. If you don't disconnect the -ve, check many many times before plugging anything in.

Cheers for pointing that out Steve, you're absolutely right.

Just to clarify - which power leads do you take of the battery(ie +/-ve), and in which order to avoid the "sparking" effect??

Its an important thing so worth clarifying...

You only need to remove the negative - you don't need to touch the +ve, so leave it all nicely covered up.

To avoid sparking as much as possible, remove the nut off the negative terminal whilst holding down the connections in order for them to continue making contact, then whip the connections off smoothly and cleanly.

To re-make the connection, apply a bit of conducting grease, then slide back on. Hold the connections on whilst you tighten the nut back up.

What happens with the majority of car alarms when you disconnect the battery? Is this not seen as an attempt to nick the car?

I think cliffird recommends putting oit into valet mode although I may be wrong
