whats ur voltage like???

[ShaKarz]

whats the max voltage u get on idle?

............and after the amps draw from it?

what would u call the operating voltage of a vehicle idle or after draw?

[Chiney]

hmm.

if i remember..i waz 14.3 at idle.. and with moderate volume my DMM read 13.7-13.9v

thats with a 30A mids amp fuh some comps and a 80A bass amp.. that waz then....

the new install now in yet.. so i`m hopin not to drop too low...

**waits fuh casper to call me with my new battery! **

[VexXx Dogg]

14.5 @ idle.

never measured on full load.

[ShaKarz]

allya did big 3 upgrade or runnin on oem ground wires ,etc.......?

[Chiney]

allya did big 3 upgrade or runnin on oem ground wires ,etc.......?

havent done the big 3 as yet..

i`m actually goin to do that now.. lol

[ShaKarz]

kool...... well update d tread after u put in ur new system.........

[Chiney]

ok..so i did the big 3... did 2 runs of 4awg to the atl from battery..

same 4awg fuh de ground as well....2 of course..

gettin a lovely 14.45v idle with headlights on brightest and deck on and mids amp playing(went to 14.3)..

wen i run in the bass amp.. i`ll update u again

BTW>> my battery (14plate AC Delco) is 2 yrs old ..so i`m gettin a deep cycle sometime soon..

[MonsterPower]

shakarz have u tested ur car?

btw do u guys use a dmm or those store bought voltage display ?

i have seen some deviate by almost a volt

[Chiney]

DMM here bro

check yuh PM one time too

[riadb]

upgraded the big 3
idle - 13.9V
drive - 14.3V
standby - 12.5V

standby @ full vol - 12.1V
idle @ full vol - 13.6V
drive @ full vol - 14.2V

using a MTX X704 pulling 60A
one battery

[casper]

^^^now thats good info

[Chiney]

nice!!
dmm reading or voltmeter?

[xeon]

is d voltage meter on pioneer decks any good? if so mine duz read 13.8....never did any upgrades, playin music it fluctuates from 12.9 - 13.3

[kurpal_v2]

^^ I always wondered about that but I dont think so cause the decks seem to take a feed of the deck +ve wire and this would not give a reading for voltage at the amps. I could be wrong though..



At idle I get about 14.3-4v
moderate volumes 13.7-8
at full I drop to 12.0-13.0

On burps I drop to 10, even saw 9 once but not for long, everything went into protection after that, had to let it cool down

[riadb]

dmm reading or voltmeter?

stinger voltmeter installed in vehicle. Calibrated using a Fluke DMM

the pioneer deck voltmeters are ok but aren't all that accurate, good for a general voltage reading with some latency.

decks seem to take a feed of the deck +ve wire

correct, the deck actually monitors the voltage through the ACC wire in you car cuz even without the memory line connected the deck will still come on when power is supplied to the ACC line

it is normally better to monitor voltage at the battery with the volt meter having it's own feed wire to the battery... voltage fluctuates too much at the amplifier power terminals due to the power capacitors rapid charge/discharge during a play cycle.

users should only monitor voltage by the amplifier if they are using low grade or insufficient gauge power cable.

[Aaron 2NR]

idle 14.1
full load 13.2 - 13.6

[spam]

i doh have a volt meter yet

[xeon]

yea pioneer the higher models.....i have the Pioneer DEH-P6800MP

[ShaKarz]

shakarz have u tested ur car?

not rly...... have to do big 3 still.............

loaded, the voltage stands up around 13v..........

but remember iz heavy load eh......

[riadb]

heavy load and u still @ 13V....daz rhell good horse

[ShaKarz]

its not rly good... it can be higher....... actually it sud be higher .. d beast comes alive round 13.8v

[Neo]

hmm...i haven't done the big 3 yet myself cause i only found about it today lmao but at full load with a voltmeter that plugs in the cigarette lighter i get about
about 13. something volt idle
about 14. something volt running
i have to take a good look at it though and record it or i have to take these readings with a DMM?
also the volts drops a lil when the bass hits lol

also i have a second battery in the back a 1.3 cap and the amps 1 using 2 30A and another using 3 30A

[ShaKarz]

i used a DMM to take my readings. i have a stinger volt meter tapped off the main battery banks but the meter itself can only be calibrated up to 1 volt under the actual voltage.... i use it as a safety feature though.... so i didnt exchange it..................

am wonderin how much would the big 3 improve my voltage by

[Neo]

you could calibrate those volt meters?...

i read that you could do it in steps and see actual improvements in your voltage

[riadb]

am wonderin how much would the big 3 improve my voltage by

The big 3 basically does this...
1. provides a low impedance high current charge line from your alternator back to your battery to improve charging efficency and charging voltage.
2. provides a low impedance high current chassis ground to improve chassis conductivity and power transfer.
3. provides an independent engine block ground to eliminate and prevent ground loops from entering the system.

It will improve your charge voltage taking into consideration:
1. the type of battery you have in the vehicle.
2. the amount of batteries connected in the system and the charge load.
3. the size of the vehicle's alternator and it's charging capabilities.
4. the difference between the stock electrical charge wires and the wires used for the upgrade.

on an average 65A alternator you should experience idle voltage to increase by 0.2 - 0.4V and running voltage to increase between 0.1 - 0.3V approx.
these #'s should increase with higher amperage alternators. Remember "good" electronically regulated alternators would not exceed a runninv voltage of 14.5V, most will be within the 14.1 - 14.4V.

you could calibrate those volt meters?...

yes you could...remove the face cover, the voltage adjust potentiometer is located to the top right of the display, a blue box with a small yellow/white screw in it. turn the screw to adjust the voltage display.

for best results and accuracy calibrate with a fluke or other high end DMM.
