OK i am installing an amp an i needed to install the power cable to the battery, OK, so i look and couldn;t find a good place on the firewall to run it through except for the hood release cable hole, so i ran the cable and here is what it looks like
(for those who aren’t sure, it is the red power cable in the pics that i ran)
hood release cable hole…
Is the power cable location bad?? should i have run it somewhere else?? where??
Thanks!
P.S. I have more slack on the cable, i just hung it to take some quick pics.
I just removed the plastic guard in the wheel well so I could shove my hands in, ran the wire and then put the guard back on when I was done, no holes no nothing. And inside the car the wire came out where the ECU is, so I’m pretty sure I did end up running it there.
Adam is that the Gromit that is just below the HArness grommet>???
I just had one there with nothing it in but then again I did not have them fancy smance options.
Wherever you end up running the wire (whether or not you can run it through the A/C grommet) make sure you have the RCA’s on the opposite side. Reason is because the power cable emits a magnetic wave and will cause some signal lose to the audio imputs on the amp. That and the least amount of power line you use the better.
You can use the grommet in the wheel well as Solarian did which
is the Acc. Gromet but I when ever working on 240’s go through
the EFI harness Gromet. Follow your injectors back to the firewall,
that big grommet with all the engines wires going into it is the EFI
gromett use that or the A/C ones if you have enough room.
Nismo_Only’s right. Keep your power cable away from the RCA cable to
avoid magnetic interference.
That’s why my RCAs run through teh middle (near shifter) and my power
cable runs through the carpet under passenger side (battery being in the trucnk).
I can’t say how much intereference but it’s the same thing I learned when
I was doing my audio stuff; keep the wires away from each other.
Signal Loss due to Magnetic Waves from the Power Cable?
You get static noise from the highcurrent power cable, not signal loss.
You can run them sidebyside just ensure you have a good set of XLN RCA’s
The length of the power cable is not the issue but the proper gauge is.
Running too small of a gauge is like sucking a milkshake through a coffee
straw, you have to work extra hard to get the same amount of work done.[/quote]
Don’t get me wrong if you don’t use the proper guage then ya it is gonna sound like hell but the least amount of line means that the amp will get the power it needs quicker which will also help to avoid things like overheating the amp and so on. I’ve been doing custom car audio for about 10 years now and even though it may not be alot there is still a difference.
Think of it this way. If you had an extra 2 feet of brake line would it not require more fluid? So if you have extra power cable then would it not require more power?
^^ WTF?? Electrons != fluid, your comparison doesn’t stand. More will be required on a thinner wire, to overcome the resistance of such a wire. Now a shorter wire will be better than a longer one, but width will only help you, not hurt you.
Length has nothing to do with anything in electronics when the proper gauge is used.
If you say you’ve been installing custom audio for 10years sorry buddie but
you must be out on the street begging for quarters installing with your knowledge.

But using the analogy of milkshake through a coffee stir stick is?
And I never disagreed with Adam. Yes if you put a 10 gauge harness on a 1000 watt amp its just not gonna work as well as a 4 gauge kit.
Dude like seriously whats with the insults?
I never said anything offensive to you in any which way or form.
And NEVER once did I disagree with what you said about gauge so why do you keep pushing that? GAUGE IS ONE OF THE MOST IMPORTANT FACTORS WHEN INSTALLING AN AMP. All I said was that the length of the wire and placement of the power line were important as well. I think that we should just quit arguing in this guys thread. Hell your a mod you should know better then that, So let’s call a truce and each go abouts installing amps our own way.
I’m a mod and should know better than not to argue with someone who is wrong?
What am I suppose to do sit back and let this guy read and believe false information?
You never insulting me? Not directly but pulling out the oh I’ve been installing for
10 years I clearly am far superior to you because I know all isn’t an insult?
Look what you said has some truth to it I’m not arguing there but Just
wanted to clarify some of the info that you were giving. There’s nothing
wrong with a constructive argument. Yes it got a little out of hand with the
insults but all one can really do is shrug their shoulders and continue…
All I meant when I said that I have been doing this for 10 years was that I’m not some noobie who put a deck into his car and I don’t assume to know everything. If I came across as an arrogant ass I appologize.
The longer the wire, the larger the gauge you need for the same resistivity. This is more true at lower voltages which is why power companies use super high voltage lines to transmit power over long distances. It’s not about quickness it is about line loss …
