voltage differences at battery and at amp


Recommended Posts

Link your batteries together with one run of 0 instead of 2 runs of 6, you'll see an improvement in voltage.

I only have my stock battery up under the hood. No batteries in the trunk. I've yet to do the Big3. I may do it once I get a job, because cash is very tight right now.

Should I get closer to 14 volts once I fix my ground?

First System

2002 Impala LS 3.8L V6, 128,365k miles.

Alternator: DC Power 190Amp H/O Alternator

Headunit: Kenwood KDC-BT945U.

Speakers: MBQuart 6.5" Comps, 6x9 3-way.

Amplifer: Eclipse 3322 on front 6.5 components, and a Infinity Kappa One @ 2ohm- 800w

Subwoofers: 2 REAudio SRX12D2 wired to 2 ohm.

Box: 3.1cuft box tuned to 33hz. sealed off to cabin

Big 3- done with all Knukonceptz KCA 0 gauge.

Don't drop below 14.1v at full tilt. :)

How are you checking the voltage?

If you're dropping 2v over a wire, and you're measuring it without the stereo playing anything, then either you're measuring it wrong or one of your terminations on the wire is awful.

10.x volts fo' life!

I'm using a Fluke DMM. I measured it with it playing...but at a lower volume. What do you mean by my terminations on a wire is awful? If it makes any difference..the wire I'm using is not the thin stranded wire, it looks like this, not your everyday wire. The "strands" are a lot thicker. Would that be dropping my voltage?

The shorter ground should help. It may not fix the issue if you crimped the connectors onto the wire poorly (what boon is talking about). Hammer and solder (using a large torch) is the cheap and dirty way to make sure the connectors are on the wire half-ass decently..

Thicker strand wire is meant for higher voltage iirc, so that could be causing an issue. You could use both 6ga runs to a distribution block then connect that to the positive terminal of your amp (make sure both are connected to positive of the battery first so you dont make a light show lol) and get a different wire for the ground.

Any time you have have a power wire next to your frame put some rubber hosing (or cut up an innertube) around it. The wire is bound to wiggle (due to driving or flex) and the casing will eventually wear through.

Wow this is some bad info the best place to ground is at the batt he needs thicker wire the smaller the wire the more resantance it has

I pull 160dbs in my big truck and allways over a 150 in my small civic with it all grounded to the front batt and I charge better that way to

But what do I know I only been doing this for 15 years with state regional and national titles

Have you ever had your woofers blown?

x2!!!!!!

but seriously, if the system isnt turned up and you get a 2v difference something is wrong. i would definitely look at all the connections. it might also be that you got some cheap ass wire that is more like 10awg. but upgrade to 1/0awg or even just 4awg. that should help.

If I answered you in a well mannered, informative way, you asked a good question or had a good attitude. If I was an asshole, you asked a stupid question or you had a fucktard attitude... or I was in a bad mood.

Yeah. im pretty sure they dont warranty retarded people.

hey i said it first ! lol

no u said it was the best if it was in the trunk lol. Ground runs to the front are just as beneficial. If we can use long wire runs for positive, then the same can happen on the opposite side of the battery.

But yea wtf is up with the lack of info here lately.
