Save your charging,and electrical system when installing a audio amp.

Every one wants the BIG amp,the more powerful,the better right?When installing an audio amp,it is good to install a addition battery,in the trunk, it is the idea place,just ground the battery to the frame or body,to a good know ground,It needs to be a large cable,1/o wire,yeah,that is big,but will keep you from having problems,then run a 1/o positive cable from the aux battery you have just put in the trunk,to the main battery in the vehicle,use a 3/4 heater hose to insulate the positive cable you have just installed.This heater hose will prevent a portion of the cable to be rubbed threw on the insulation of the cable and shorting out.Then install the amp.Now ,for better electrical control over the charging system of the vehicle,you can install a isolator ,to separate the circuit,and still charge the battery up with the vehicles alternator.Install the isolator at the vehicles battery and the positive cable you just ran.The alternator will charge the aux battery,and the vehicles battery,and not affect the running of the vehicles engine,or charging system.Be sure to connect the amp to the aux battery only,and the aux battery needs to be a good strong battery such as a 65 style battery such as for a full size ford crown victoria.These batteries are full of power.There you are,you are ready to thump,and do it safely .You need to install a fuse holder between the positive cable from the aux battery and the isolator,use a max link fuse holder and fuse,and a strong 60 or 80 amp fuse,this will blow into before starting a fire,.

Ok fuses hmm maybe the wrong size amp but what is sucking the life out of the alterneter

Your fuses have nothing to do with current draw, all they do is keep the wire that they are in line with from melting and starting your car on fire! The problem you have is the same as all the rest of the people who do not plan out their car stereo system. Your stock alternator is made to keep your battery charged while you drive it, with very little extra power needed for the power windows and AC. Most cars have a 80 to 110 amp output alternator, but that's not a continuous draw either. That is a top output while it's recharging things it will get super hot after a while of high output and will burn up the diodes in the regulator eventually. If you have a 100 amp alternator and it has 30 amps of power left over after charging the battery and running your AC it certainly will not be able to power up an amp that has a draw of 60 amps or more. Your alternator never has a chance to catch up to normal charging of your battery even. You'll find your battery will last about 1/2 of the rated life from never getting charged full ever, your alternator will die every summer and your amp will be another one of those that are stacked up on my work bench in need of parts due to burned up power mosfetts from under voltage and over amperage on the rails of your overdriven amp. You will be doing the same as the last ten others with this same problem, you will be shopping for a new HO alternator, new Battery and a new Amp but will not be doing this until after all these things have been replaced 2 or more times. Then you will remember this post I wrote for you telling you that these things need to be done first, before even getting started on building a system. Once you realize the cost of the entire project you would probably start thinking about getting components that will be drawing less current and not have to be replacing everything along the way. It took me 10 years of working with12 volt systems to come to this conclusion and the last 25 years trying to get others to understand the cost involved to do it right.

JL Audio 750/1 installation help

upgrade all 12v wires running to your system to 0 gauge to kill you wiring to small problem when dealing with systems bigger is better double check to see if you alternator is putting out enough power for everything just because it say it will doesn't mean it does upgrade your capacitor seems to be falling you because there made to store power when needed and also get your battery check for any defects and add and extra just for your system

So i hooked up the amp useing the pre-existing 8 gauge wire with a 30 amp fuse it worked for about and hour and started blowing the 30 amp line fuse. i replaced the line from 8 to 4 gauge and installed an...

this sound like a case of arcing power wire it happens very very easy if u use cheap wire especially from walmart. whatever u do keep using fuses and get a batt test asap. if u take out the fuses ull burn the amp like no other and plobably burn out the power rails which will be cheaper to buy a new amp after that

Kenwood KAC-729S keeps blowing fuses. Checked all cables, re-ran power, remote, and ground. All good, still blows them at power-up.

Hello opey_69a,

Here are the troubleshooting steps for fuses blowing.
1) Remove all wiring except ground, power and remote and see if the amp powers up without blowing the fuses. If it does, the problem is in the input cables or speaker wiring.
2) The use of loudspeaker impedances below the recommended minimums will cause the amp to draw excessive current - check.
3) A shorted or grounded RCA cable may cause the fuses to blow - check.
4) If an amplifier fuse blows continually, with only +12 volt, ground and remote leads connected, the amplifier is probably defective, most likely shorted output MOSFET's. In this case the amp needs professional repair or replacement.

Hope this helps.

Amp keeps blowin the two 30amp fuses on the amp.

Make sure that the speaker wires are wired correct at both the amp and the speakers......otherwise it sounds like the typical death of a power acoustik amp (great amps, but prone to a premature death)

Rockfordfosgate amp 750s car problem

Disconnect all speaker wires and RCA cables from the amp. Replace the fuse with a 30 amp fuse and power up the amp. If the fuse blows, the amplifier probably has shorted/leaking output transistors.
