Ground wire
By Kim1 - usenet poster
First:
Can I ground my amp with 4 awg wire if the power wire is 8 awg???
Secondly:
I've an amp fused at 40 amp and another fused at 60 amp...
a sony XM-754hx and a Pioneer GM-X922. My main wire is 4 awg Phoenix Gold
about 16 feet long, and I've a distibution block, 1 4awg in and 2 8 awg out.
Is 8 awg wire for the sony and pioneer amp are ok, if the 8 awg wire is
about 2 foot long max? And I've a 1 Farad Cap.
Thanks

It really depends on the setup you're using. You HAVE to have the same size
power and ground when conecting to a capacitor. In other words, the cable
from the + side of the battery to the capacitor and from the capacitor to
the power distribution block has to be the same size as the cable from the
capacitor to ground and/or negative distribution block. After this, you're
fine. If you want to run a 4 gauge cable from the + of the capacitor to the
distibution block and then use 8 gauge to run to your head unit or
amplifier, then it's still OK to use the 4 gauge from the - side or the
capcitor and run it straight to ground.

I believe it has to do with the resistance of the different gauges of cable.
If you have significantly different resistance in the two cable you will
have an elecrtirc potential difference. This will cause current to flow on
one direction or another, thereby discharging your cap every time it sits
for any length of time. Plus, the instructions on all capacitors say you
need to have the same gauge. If you don't buy my explanation, you should at
least trust the guys who make and distribute the caps. :)

Does more power and more current draw mean anything to you?? I suspect
you had another problem other than what you think. Were the brake lights
the only ones dimming... err turning off?? Nothing else?? Seems to me
like you had another problem.

Seriously. Its kinda like buy a bigger car cuase you brakes don't work on
your current one. Now, I mean I can see switching from a huge old amp to a
newer class D may solve the problem, but that is not the way out. Look for
the cause of the problem rather than getting rid of something affected by
the problem.

<< ok, In my opinions I need the cap because my light dim when the music is
loud. >>
<<Get a better battery.>>
this won't really help.... the reason that his lights are dimming is because
his alternator can't handle the load, which passes the load on to the
battery... going from 14.4 volts down to 12.5 volts is what's causing the
dimming. battery capacity of any $50 die hard battery should be enough for
system duty... and if it's not, then you probably need a rewound (or bigger
replacement) alternator.
a 1 farad cap will probably solve your dimming headlights problem... possibly
even a 0.5 farad. if you've got a little extra money to burn ($20 difference
or so), i suggest getting a 0.5 farad and seeing if that solves your problem...
if not, get another 0.5 farad and you've got the equivalent of a 1 farad
capacitor with better properties.
my lights dim slightly when i'm pushing my amps, but i just don't give a
shit... i let it. 8o)
take care,
Mike Kim

Caps are too expensive and I feel that they are not real good value for
money, especially in your set-up.
If your lights dim better off selling your existing sub amp and buying a lot
bigger sub amp, preferably one with double the power.
I will explain why. I bought a Phoenix Gold M50 and used it on my two
10inch earthquake subs.
My brake lights would turn off when i was stationary at the lights!!!! (and
this was during the day without anyother electrical device in the car being
used)
I sold the amp and bought a Phoenix Gold MPS2240 to run the same set-up.
No problems no lights have dimmed ever since!!!!!!!!!
This up-grade cost half the price of a 1 farad cap.
Now i run a PPI A1200.2 and a Adcom 5475 (total maximum rating of 1800watts
rms) in the same car no probs.

riCh,
is there a big difference in SQ on the XM-752X (blue one)
and the 752EQ (red with 5 band EQ) ?
You were talking about the 752EQ then ?
I am just looking for a 2ch amp with built-in xovers
on it in $150 range... any other recommendations ?
Right now i got Infinity Kappa 102a, i was about to
order another one but they sold out :( I am using 102a
for my db10 sub right now and i am looking for a second
amp for my front speakers.
I have to get something this week!
Thanks!

Sure. As long as your ground wire is always of equal or greater capacity as
your power wire, you're fine. It's when your ground is too small that the
amp tries to source ground current through other means (i.e., RCA's) and
starts having problems (i.e., noise).

Yes that sounds good to me, 8ga is ok because it's a short run and you
probably can't fit 4ga in to your amp. But you should add another 4ga
ground cable from your battery negative post to your chassis, remember
what comes out of the positive side must go in, so try and keep the wire
gauges the same on both sides..

If you are using 8 awg for power because you actually need to, then the
ground should definitely be 8 awg. But if the load on the power wire would
have been suitable for a 4 awg wire, then you could use the miss-match you
proposed.
