Amp was hooked up without fuse from battery to amp

The amp was wired in with out the fuse between the battery and the amp on the positive cable and it burned the amp a little i was wondering if the amp is salvageable and about how much it would cost to fix it. Its a newer rockford fosgate 300 watt mono amp.

Sounds like a output fet shorted and then instead of blowing the fuse it burnt your power supply up. email me fiercekane@hotmail.com if you are interested in getting it fixed, I stock the parts or I can sell them to you. Thanks...

Another failure must have occured, as the fuse would have blown, possibly limiting the damage, however something did fail to start the problem.

Nobody can give you an honest estimate without analyzing the damage.
A wild guess would be one-half the cost of the unit.

Jl500 amp... Been hooked up the same way for years. Power wire from battery with an inline fuse which goes back to the power block which goes to the amp. Perfect ground and remote wire to the deck. And RCA...


well the nasty spark it shoots its because you r to first connect negative first always and than positive or check ur main cable/fuse that is connected to your battery inside the fuse box its actually pretty easy to find just follow the positive red wire from your battery till u get to the fuse box it looks like its connected to negative and positive, check it it may be the problem(inside the fuse box), if it isn't you should check the main source of battery recharge which is your alternator it may be going bad

Truck will not start how can i tell if its a starter or selonoid


does it spin real fast without clanging and grinding against the flywheel? if so then its probably the solenoid bad. do you have to hit the starter with a hammer then it works? it is probably bad brushes or a worn motor. eather way i think you can only get a new starter and solenoid together not sold seperate. check for bad battery cables (loose).

Ok 1994 vw passat... battery wont hold its charge.. new battery new alternator.. battery cables look old and worn.. when I turn the key sometimes there is nothing just the fourways trun on.. I then unhook...


the wires on the positive post are the large cable goes to the starter, one of the smaller wires goes to the charging circuit and the other goes to the fuse/relay power center, now how to check for a draw on your battery, first you need to remove the battery and have it charged you can take it to auto zone and they will charge it for free. after you have the battery charged hook up the negative battery cable but do not hook up the positive cable, make sure every thing is turned off and all doors and trunk are closed, then take a 12volt test light and hook it between the positive battery post and the positive battery cable if the test light lights up you have a draw, if it lights start pulling fuses one at a time till the light goes out. when you find the fuse that turns the light out you found the circuit that is drawing on the battery. now i cant tell you what in that circuit is drawing you will have to come back on and tell us what fuse it is and we can look up what all is on that circuit, if the light stays on after all fuses have been tested unhook the alternator if the light goes out you got a bad alternator......GOOD LUCK

96 Olds Aurora wont start nothing happens when i turn the key,battery is good.


CHECK THE INSTRUMENT CLUSTER FOR POWER TO GAUGES TO SEE IF THEY WORK WHILE IGNITION IS IN THE ON POSITION.IF NO CHECK THE 40 AMP IGNITION FUSE.IF FUSE GOOD IGNITION SWITCH IS BAD OR HAS A LOOSE OR BROKEN WIRE.IF FUSE GOOD ALL GAUGES IS WORKING.I BE LOOKING AT STARTER AND STARTER SOLENOID.REMOVE THEM HAVE AUTO ZONE TEST STARTER.OR YOU CAN GET A REMOTE STARTER SWITCH AND SET OF BATTERY CABLES.HOOK BATTERY CABLES TO A BATTERY.WITH STARTER OUT OF CAR TAKE BATTERY CABLES HOOK NEGATIVE BATTERY TO STARTER BODY FOR GOOD GROUND.TAKE POSITIVE BATTERY CABLE HOOK TO STARTER POSITIVE TERMINAL WHERE POSITIVE BATTERY CABLE GOES.THEN HOOK THE REMOTE SWITCH RED WIRE TO STARTER POSITIVE TERMINAL AND THE OTHER REMOTE SWITCH WIRE TO THE S OR SWITCH TERMINAL ON STARTER SOLENOID.PRESS THE REMOTE SWITCH IS STARTER RUNS GOOD WITH NO FUNNY NOISES ITS GOOD IF STARTER DONT RUN THE STARTER SOLENOID OR STARTER IS BAD. THE PROBLEMS IN YOUR CAR COULD BE A BAD KEY TRY ANOTHER KEY YOUR CAR HAS THE THEFT DETERRENT MODULE SYSTEM BEST TO HAVE CAR SCAN TO CHECK THE THEFT SECURITY MODULE AND THE TRANSMISSION NEUTRAL SAFETY SWITCH IF ITS BAD STARTER WONT WORK.ALSO CHECK THE THEFT DETERRENT MODULE RELAY. BEFORE REMOVING BATTERY CABLES TURN OFF RADIO SO YOU WONT LOSE YOUR RADIO PLAYING CODE.

My amp wont even turn on or red light or nothing so what do i do


check ground cable, check fuse on amp, and check the fuse under the hood, on the positive cable should be about 12' from the battery, if all is well and theres no light, check the blue wire coming from your deck use a tester,if bad you can run one of your fuse box ,place a 12volt switch and hook it to the amp you should be good to go

How do i intall my amp?


first you need to run a power cable for the battery to where ever you are going to place the amp DO NOT hook the cable to the battery until the very last just wire it to the amp for now.next you will want to ground your amp hook the ground wire to the amp and the other end to a solid piece of metal in the car this is very important if you don't get good metal on metal contact you'll blow a fuse. If you can hide it well strip back a bit of carpeting and use sand paper to remove all paint from the metal and drill a hole for a screw. once that is finished you will need to run a remote wire from the amp to the car stereo usually these are the blue wire on the harness in the dash. once that is hooked up run the rca cables (reds and whites) plug in to amp and then in to back of cd player. once this is all hooked up and fully secure hook the power cable to the battery make good contact and if everything is grounded right you should get the lights on in the amp. Next step hook up the speakers run speaker wire from the amp to your speakers make sure negative goes to negative and positive to positive or you'll get clipping and it will sound like ****. that's pretty much the jist of it. if you have any questions let me know.

Battery hook-up


You must have inline fuses at the point where the wire taps off of the power source. If you're tapping off a wire that has no fuse (like the starter solenoid), you must insert a fuse.

When making the connection to the amp, there will be a spark initially. If you hold it on for a second, pull it off and then touch it again, there should be little to no spark because the capacitors in the amplifier would have charged when you made the initial contact. If there is an intense spark each time you touch it and the amp is not on (no remote voltage applied), the amp may be defective.

Let me know if you have any other questions.
