The spark could be from the capacitors in the amplifier charging. Make sure the main fuse from your battery is still good and also check all the fuses on the amplifier. Verify all the wiring is correct and make sure none of the wires from inside the positive cable are poking out and touching the vehicle or amplifier chassis. If you have a 1k ohm resistor, you can put it in series with the amplifier power line to slowly charge the capacitors. You can do that by following the directions from the link below. After doing all that, remove the 1k resistor, hook it all up and try it again. If it still doesn't work, make sure your remote wire coming from the head unit has a voltage on it when the head unit is on. You can get a cheap volt meter from a hardware store or wal-mart.

I was given a subwoofer and box but do not know where to go from here in terms of hooking it up in my car. It is a Rockford fosgate punch p112s4.


First youll need an amp. Depending on what size the sub is a 500 watt rms amp can hold up to about a 300 watt kicker. If your looking for something bigger u can get a 1000 watt amp and hook up two 300 watt kickers. To hook up the amp youll need a car amp power cable, power control cable, speaker wire, amd a car amp ground wire. They usually sell kits that run aboyt 40 bucks. The power cable goes to the batter as well as the ground cable. The power control cable goes to the back of the head unit. (You will kost likely need a more modern headunit if urs is stock). Once this is done put the sub in the box (i recomend super glue because metal nails take away from the bass). Put the speaker wire to the speaker positive on left negative on right. Same with the amp. And now ur bumpin ;)

I have a jl 500/1 amp hooked up in my car and the power light comes on for about 5 seconds then turns off. no sound out of the subs. it is hooked up to a factory deck through a high to low level converter....


hook up the remote wire ( or make sure its hooked up good) check your ground! ground wire not big enough awg wire and put on bare metal not more than 1 foot away from amp. bad ground will cause this.

I hooked up a punch 250 a2 amp the l.e.d came on with no problem then i turned the car on and the amp smoked a little bit did i blow the amp the l.e.d still was on i just unhooked quickly to be safe


Hopefully you havent blown the amp, check ALL of the wiring, make sure that your earth connection is connected to a clean metal area and make sure that the power cable you are using is big enough for the job. The Punch range of amps require a fair bit of power. skinny power cables wont help your situation and if too thin, then the amount of current could melt the plastic casing could cause a fire.

Amp shut off has power and grond and remot but only my p550 shut off fuses are ok and all other amps are wourking


how many subs are you running on this amp, and how many ohms are they. if the are bridged, try hooking up stereo and see if the problem still occurs. make sure your scrape off all the paint where the amp is grounded to the frame which should be less than a few feet. i'd also recommend running at least a 4ga wire for both your power and ground.

I have a old 2001 rockford fosgate 2 channel p5002 model in great condition just need to know how many watts is it and which subwoofers are compatible to this amp? thanks


Your amp is rated at 500 watts. Here is the break down of your wattage.

125x2 at 4 ohms
250x2 at 2 ohms
500x1 at bridged 4 ohms

When hooking up the amp make sure to use 4 gauge power and ground wire.

As I said in the previous post no the wiring kit is just fie. Yo uwill need to change the inline fuse and that is about it. The problem exists in how you have your subwoofers wired and what impedance is being presented to the amp. Please read my previous response to your your post.

Amplifier has no sound


Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty. Your amp is clipping.
A thumbs up would be greatly appreciated if this answer is helpful to you. amplifier-no-sound-peeu4x5nsxvd53n2rwetiqa4-3-0.jpg

Something Wrong With my Fosgate 500-a2 Amp


Is the amp being fed directly from the head unit's RCA preamp outputs or is it being fed by another amp's preamp outputs? Try temporarily wiring up a speaker you know is good in place of the sub and see if anything changes.
