Question about Jl Audio 300/4 Car Audio Amplifier

1 Answer

Can it Be Fixed

Amp was connected directly to positive and negative terminals on car battery. spark flew when positive lead was connected to positive terminal. Front channel had RCA's already connected to the receiver. Now the amp powers on, but the front channel doesn't work at all, and the rear channel is terribly distorted. - What exactly happened, can the amp be fixed, where should trouble shooting begin, and what should be looked for. Thanks.

Nothing should have been damaged. I would assume the speaker output shorted in one way or another...did you have a speaker hooked up? You most likely blew the output transistors and they ALL need to be replaced as one going bad will kill the rest since they're so sensitive. At least the PSU, seemingly, wasn't damaged. Contact www.audiotekx.com, ask for Jason, he's excellent at repairing amps and has great pricing.

Bridging two12" subs and one 15" sub to my Rockford fosgate T 1500bd amp

assuming all 3 subs are 3-4 ohms, running all 3 in parallel (the 3 positive leads all attach to the amp positive terminal, and all 3 speaker negative leads connect to the amp negative terminal) will bring you at or above 1 ohm, which the amp is capable of handling. With 1500 watts, you will want to use 8 gague power leads for the amp, 12 gague speaker cables, and an inline 120 amp fuse between the amp and the battery, within 1 foot of the battery.

Battery sparks on hook up positive and negetive terminals are correct

You will get sparks if you connect or disconnect the battery incorrectly. The problem with sparks are they can fire voltage and current spikes down wires to sensitive electrical/electronic components, meters, clocks, alarms etc.

There is only one way to safely and correctly remove and re-fit a motorcycle battery. To remove it undo negative lead first then positive. To fit/refit a battery connect positive lead first then negative. Hope this helps

I changed the battery and negative treminal for my 1995 ford escort and as soon as I hooked up the battery it blew the 100 amp main fuse under the hood. I replaced the 100 amp fuse and hooked the battery...

At a guess, I'd say that you have got the new battery in back to front. This means that you are hooking the earth wires to the Positive side of the battery.

Where is the negative side for my ignition coil?

In all the automotive vehicle the positive terminals are connected to the body/frame. the wiring which runs around for all the electrical part is always negative terminal.

Smilarly the ignition coil lead is one terminal & the body of the spark plug is other terminal.

That is the reason you see the spark jumps from the center to the lug in spark plug.

Tried to jump my 2003 galant and the cables would spark when trying to connect negative

Be ceratin you have jumper cables to correct terminals. Also, you may connect both jumper cables to the battery of the car your getting power from (be certain not to let other ends of cables touch) connect the positive lead of car being jumped to the battery's positive terminal, then connect the negative lead to the cars ground, not directly to the negative on the battery. Getting a spark when jumping is very common. You do not want to create the spark at the battery because the fumes from the battery acid can be explosive...... That can go very bad! When removing remove the grounded, to the jumped car, and then carefully remove the rest. Again be certain to not let the leads touch.

Please let me know if this had assited you,

Thanks,
Tom

Battery/starter malfunction upon reinstallation of battery

are you absolutely certain that you have the battery back in the bike the right way,as what you have described is battery leads around the wrong way,because if you hook up the positive to the neg terminal and negative to thepositive terminal the bike will try to start(but backwards)as you have effectivly turned the whole electrical sytem inside out,i just hope that the cdi and coils havent been damaged..i certainly hope that,all you can do now is put the battery back on the charger and let it trickle charge,track the leads and be certain which is which before putting them back on (positive is red,negative is black)and the battery should be clearly marked,not only on the front but beside each terminal,hope this helps

Keep blowing fuse under hood when i put power wire in to amp

disconnect the negative battery terminal, replace the fuse with all the wires hooked up to the amp and reconnect the battery terminal, that way the initial surge of power goes through the negative terminal and not your inline fuse. That should solve your problem.
