Posted April 3, 201312 yr So I'm getting a voltage drop to 13.8 after the second song or soI check with my voltmeter i bought cause some1 on here told me i better buy 1and the reading is 14.4 before the fuse13.8 after i'm wondering if this is from the resistance the warm fuse?im running the proper size fuse1 run of 1/0 gauge now what I really want to know is if the drop is from the fuse resistanceis this something i should worry about going full tilt? should i add another run of 1/0 gauge? (i have 20ft of knu ofc forsale/laying around but id have 2 buy another fuse) stock alt2 yellow topshifonics colossus bridged @ 2ohm (3600 watts supposedly)RF p400.2 -midRF p200.2 -high(2) DD 2512 also at red lights when going full tilt i hit 12.3-12.1is it dangerous to play loud at that voltage level?what if it dips to 11.8? Thanks
April 3, 201312 yr the 14.4 before and the 13 after i would look into what kind of fuse holder you have.. it seems to be cunducting poorly, check the connections and look for any corrosion and so forth adding another run would not hurt. why would you play your stereo full tilt at a redlight, that is rude, and give car audio a bad name. please stop, but yes, your amp will start clipping, and your amp can catch on fire from playing with low voltage, not saying it will at 12 volts. but 10 volts yup it sure can.
April 3, 201312 yr average drop between cars can vary, but in my car with 3 runs of 4/0 i drop .3-4v between the front and rear.
April 3, 201312 yr Oh for some reason i thought he meant right after the fuse .. not at the end of his run
April 3, 201312 yr I assumed he meant right after as well the way it was worded. If you meant it was 14.4 up front and 13.8 in the back, that might be just the wire heating/warming up and causing a bit more resistance.
April 3, 201312 yr If you guys are assuming right, the reason for a drop in voltage in the rear is their is no ground run from front to rear. Every vehicle out there i've measured loses between 0.3-1.2v by not having a ground run.
April 3, 201312 yr And if that's correct, jon is spot on, that's a BAD holder And, hehe, if that's the case, i'm ALMOST..... pretty close, willing to bet it's a knukonceptz fuse holder if the voltage drop actually occurs as part of the block\fuse itself.

Every vehicle out there i've measured loses between 0.3-1.2v by not having a ground run. i got a run of 1/0 gauge from from battery (-) to rear batt (-) too the 14.4 before and the 13 after i would look into what kind of fuse holder you have.. it seems to be cunducting poorly, check the connections and look for any corrosion and so forth adding another run would not hurt. why would you play your stereo full tilt at a redlight, that is rude, and give car audio a bad name. please stop, but yes, your amp will start clipping, and your amp can catch on fire from playing with low voltage, not saying it will at 12 volts. but 10 volts yup it sure can. man i was impressed til you said that shit about not going full tilt at the red lightwhen i play loud at red lights there is no other cars around meinfact rarely are there any cars around me out here and i just used red light as an example of the car stoppedi see it when i demo at my friends too no corrosion, fresh equipment and its 14.4-14.2 before and 13.8 after not 13 and yes guys i was testing right around the fuseas i am noob and there is a little wire showing on both ends I'm so lost as to how a fuse holder can cause this problemwhen a fuse holder is so simply designed and applied ive heard alot of bad stuff about knu fuse holders and dist blocks so what is the recommendation?..............add another run?change to a diff fuse holder?keep it as is since 13.8 is as low as it sits?
April 4, 201312 yr You should probley be good. Iv seen some peoples car show the high 13s always. Couldn't hurt to try a different fuse holder just to see if there is a difference
April 4, 201312 yr If you really want to be sure it is the fuse holder, measure the drop across the holder. Put one test lead on the input of the holder and one on the output. Put it on DC volts. With your system playing, what is the highest reading you get? Until you do this, it is speculation about the holder...

April 5, 201312 yr the way how their furrow fittings work sucks. I'm curious on something though since that much voltage drop across just a few inches is rare.. how hot does it feel if you place your hand over and around the fuse holder? Feel both ends, does any of it feel warm or hot? It should feel cold.

Feel both ends, does any of it feel warm or hot? It should feel cold. it is a little warm all around but not so much that i cannot touchi'm nervous about how much worse things will be in the summer ive had problems with scosche fusesi figured going with knu i would be ok..... It seems a little off though because I am only running a stock altits not like im pushing 220 amps through the fuseand it is a 300 amp fuse anyways idk maybe the fuse holder is way less conductivethan my ofc 1/0 gaugeso when the current hits the fuse it has issuesall thats guessing tho i just thought a fuse holder is only 2 pieces of metalhow dumb does a company have 2 be 2 mess it up
April 5, 201312 yr no you measured voltage. hes telling you to measure the resistance of the fuse holder.... NOT the same thing.
