how powerful is the amp?
where is the amp going?
boot?
on face of it idd not recommend that connection

Not ideally, no. It's physically possible, but not recommended as the power drain might be too much for it, even if it is only a 50w amp.
The last thing you want is overheating electrical supplies and cables behind your dash!

dont do it
wire it from the battery the amp will take a big drain no matter how small it may seem.

id say no.
and is that 50watt max? if so whats the point!?
perhaps its 50watt rms?
i presume you dont have the power feed in the boot already. ( ithink the LCRs dont have it)
id not recommend connecting it there. and its not much mroe hassle to connect the the battery.

No no no no no no no no no no NO!
Take it from the battery direct. The cable between that distribution box and the battery can't cope with big loads.

I wasn't paying much attention during the electronics talks at school obviouslyNo no no no no no no no no no NO!

Cheers for the link.
Is it still considered wrong to route rca leads down the same side as power cables?
Yes it is. RCA's are likely to pick up interference if you do that, which will leave yuo with a dirty great amount of alternator whine.

Yes and no. You probably wouldn't know the difference but it's always safest to keep them apart anyway.
keep them apart
shouldnt really be running signal wires next to power wires as it can cause a low hum or an interfernce
also make sure you've got a good grounding point!

Actually it's the bad earths that cause the interference. You can wind the RCA cable round the power wire all the way down the car and still not get any noise... But it's just safer to keep them apart anyway.
That's quite different to what I found. I was asked to check over a car because it had terrible whining through the speakers, which were amped. The first thing I noticed was the power, remote and RCA leads were all running down one side of the car. I changed this so the power and remote lead ran down one side and the RCA's ran down the other and the noise went away. Nothing else was changed.
In my own car, well an older car of mine (Focus) I had a bad earth that caused the whining too, so I'm not in any way disputing that! It's seriously annoying when you've spent all day installing your kit and on the first test drive... whining

If the insulation on the cable's is good enough then no interferance can be caused but as power cable's are insulated diffrently from signal cable's it is possible for it to effect if there next to each other! Also as the power cable is run down with out a netrual run down next to it theres also the chance of magnetic interferance from the power cable as well (i think)!!!
Last install i did i removed the glove box and drilled a new hole and fit a new grommet! just don't drill into anything!

Got me slightly worried now. I wired my active sub to the power block under the dash on somebodies recommendation.
On the positive side, i've been using it like this for 2 years with no problems........
Might just look into this further

It's one of those things that really shouldn't be done, but some people do get away with without trouble. But if there is a problem - and to be honest it's quite likely for most cases - then the first you know of it is when it's too late and you have overheating electrical cables behind the dashboard on your car. Not a great deal you can do about that!
