Very well done. I like that you took the time to explain that voltage drop measurements are to be taken while the system is UNDER LOAD. I will say that the voltage drop measurement you are taking is proportional to the current of the load. Therefore the voltage drop will be higher when you turn up the volume (Vdrop = I_load x R_wire/connections). To add further information, you are testing the voltage drop due to the electrical connections and NOT the system drawing more current than the alternator is capable of providing (therefore resulting in the voltage dropping to battery voltage). You should do a separate video explaining that the alternator can only provide the current it is designed to and that adding extra batteries is not going to solve voltage drop issues. In order to maintain 14.4V+ you need to have an alternator capable of the system demands (or multiple alternators).

Used voltage drops for years and would make one small comment on checking your grounds. The body grounds are usually much small than the power side. This one area is easily overlooked when you see a large power cable going to the engine block followed by a tiny wire going to the body. And you have a excellent series of videos didn't start using plastic until I viewed your site.

Awesome vid Mark! I recently needed to test for voltage drop, the ultimate problem being with my fuse block. Accidentally installed a washer between the fuse and block, which caused a high resistance failure point. The fuse for the subwoofer amp began to melt during some serious hip-hop bass segment, but never went full-blown. Won't be making that mistake ever again. I get less than .1 volt drop after getting a new fuse block. The factory amplifier ground points under the seats were never used, and gave me a great grounding spot! I was aware of the resistance test but never load tested a ground point before, that's a great test!

The engine bay fuse/relay box has 2 positives one from the alternator both show 12.67volts (i realized after my interior lights were on if that makes much difference) the only thing i couldn't test was the resistance from fuse/relay box positive to my trunk glad i found this it helped alot since i am adding a 8k rms amp soon and i am pretty positive now my electrical is looking healthy... only thing i have to do is beef up my 140amp alternator

I learned back in the 80s using an opened box for subs allows woofers to travel as though they are in a lot huger box.

Music used to test Patrick O’hear David Helping examples shows the highs and lows better than like rap 60 db bass. Give me comments what you think. I love learning.

Well usually the chassis ground will have a much lower resistance than ~0ga all the way back to the battery... and it’s the common ground so on top of keeping the impedance minimal, it should also help minimize system phase issues while keeping cost low (ofc ain’t cheap ya know.) so use that bucket of saved money to further enhance your system by acoustic treatment, add or upgrade your dsp, add loudspeaker horns on the roof for hollering at bitches etc.. you know .. things that really matter

Then have resistance of The Wire that alone can cost you up to one volt depending on the length of the wire and size ? Just say. Good vid mark keep it real

You can treat wire as resistor and calculate power on it, for your example you have 1v on it when 100A is passing through it, that makes it 1V/100A=0.01Ohm (10miliohm), also power can be calculated 1V*100A=100W. Since wire is in series with load (using kirchoffs law) you have to get total power by adding power on wire/resistor and amplifier on this example, so 1440W=1340+100W
@cekpi7
5 жыл бұрын
Also your amplifier will most likely produce more power at 14.4V than it would at 13.4V so most likely you are gonna get more than 100W just by upgrading wire.
@Chris-sw4xo

Cekpi7 Measure the voltage with the car on and the system playing at whatever volume you normally play. When the bass hits your gonna see the voltage decrease. The best bet to get all the voltage you can is upgrade the alternator, run over sized quality wire, and add batteries. That’s the biggest problem when people add systems to their cars they don’t think of upgrading the electrical. Stock alternators only have a little head room and can’t keep up the the demand of a big amplifier.

No wires to reach from the front to the back I am guessing you could use jumper cables. Just connect the cable to the negative you disconnected from the battery and use the other end for the DMM. Not sure if the jumper cables are quality enough but it should work.

Can I use wire or alligator clips to extend my leads to measure resistance rather than buying that suggestion off Amazon?

Great video. I was always told its better to make yr own ground instead of using existing ground screws or bolts. I've had success with both. Depending on location & voltage. What do you think? Thanks
