I have got a new kenwood 350w amp and 1200w sub, and have wired everything as per instructions, but had a spark jump from the power cable to the ground cable, will this affect anything?
I have a DEH1050E pioneer cd tuner and have connected the rca plugs to the jacks, and getting no sound, is there anything else to be done? and does the power control jack on the amp need to be wired in to work the sub?

Re: nothing working! please help!
No it doesnt HAVE to be wired in it just lets you control the amount of output from the sub. however the spark could have blown out the internal workings of the amp. there are genereally multiple fuses on car amps. have you checked these? if they are blown replace and reinstall if not then it very would could be that the spark caused the amp to fry.

Ok. Simple test to check if your subs are blown. Hook up speaker wire and simply touch each wire to each end of a new aa battery. You should hear like a sizzling static sound from the sub and it should jump slightly if its good. If subs are good you may be having issues with the connection terminals or worse. And it could simply be the audio connection from the stereo or the audio wires need replaced. Possibly replace the stereo or amp. So many more options but this should get you headed in the right direction.
Sony is not a bad brand if you use it correctly... This is what is happening my friend. You are what is called "clipping" your amplifier. What you need to do is make sure you are running your subs at the correct impedance or also known as resistance. Then make sure you are running them at the correct frequency, there is a turn tab on the amp to match the sub to the amp. Then never never turn the gain all the way up. This over works the amp and will wear it out much faster. This also does not actually give more power to the subs it just gains the power sooner then later. Never turn the gain more then half way up.. Hope this can step you in the correct direction my friend.
The Kenwood KAC-6202 2-channel is only rated for 60 watts RMS per channel into a 4 ohm load. That just isn't much power for a pair of 12" subs. Even the bridged output is only 200 watts into 4 ohms, still at the low end for a sub, much less to share between a pair of subs.
Assuming that your subs are 4 ohm, you could probably get more sound by driving just one of them on the bridged terminals. But to get the best power with what you have, connect one sub to each channel, set the filter switch to the far right (LPF), set the operation switch to stereo (both channels driven), set the filter frequency (Hz) to 100 or lower, and adjust the input sensitivity as far clockwise as possible without causing distortion.
But, to do the subs justice, you really need at least 300-400 watts to share between them.
bignatedabal: You can't get something more out of a device than it's rating. In other words, if you have a 400W amp that's all it's going to produce. For example if you're looking to drive both sub spkrs @ 350W each then buy a sub amp with a rating of 700W @ 2ohms & connect your 4ohm spkrs in parallel to the amp. Each spkr will produce 350W of sound if everything is installed correctly.
1 thing to look for in amp mfg's. Look for those who rate their amps in RMS power. This is the true output rating. Many amps are rated in peak-to-peak which seems great but doesn't tell you the real story, unless you know how to do the math to determine the RMS. The better mfg's will take the time to test their amps & rate them properly. Also look for massive heatsinking (the cooling fins). I consider cooling fans to be a benefit as well.
check for any loose connections at the fuse block or a loose fuse
using an ohm meter would help
check the harness on the back of the radio for loose connection
bad igntion switch, again an ohm meter would help !
what type vehicle ?
you can simply take the input and connect it in parallel to the input of the second amplifier. The output of one amp will go to one speaker, and the output of the other amp will go to the other speaker.
The inputs of amplifiers are "high impedance" so putting more than one in parallel won't put any strain on the radio circuit.
Unplug the inputs and outputs from the amp (be sure to mark the wires so you can hook them back up), leaving only the ground, +12, and remote wire hooked up. Now, turn it on. If the amp light goes red, the amp is broken. If it goes green, turn if off, plug in the speakers, then turn it on. if it's red, its a speaker problem, if green, do the same with the inputs, and you'll have your answer.
The problem would be if you had it switched around. The 1200W subwoofer only means that it can handle 1200w of power the 1000w amp means that it can deliver 1000w of power. What you may have is an impedance mismatch. My question is what is the resistance rating on the sub woofer and what is the minimum resistance rating of the amplifier. These are actully the important issues at hand.
the rating of the subwoofer resistance in Ohms should never be lower then the minimum resistance rating on the amplifier. in fact the resistance rating on the amp should match the resistance rating on the subwoofer.
