Ive recently had my sub woofer un secured banging about in my boot, and it finally caught up with me, it endid up slamming into my amop and breaking the RCA's leaving them breaking inside the imput plugs, so what id like to know is would this be easily fixable, and would i risk damaging the amp by taking it apart, as well as is it possible to connect new RCA heads to the existing cable? (Dont wana rewire it again :P) Any help would be greatly appreciated Cheers Hamish

Hello The power rating for this amp is as follows. Two channel: Sub woofer: Min 35Watts Two channel: Other than sub woofer : 70Watts One channel: sub woofer; 100Watts One channel: other than sub woofer: 200Watts. OK.
A 4 Gauge or even better a 2 Gauge power cable Starting from the Battery going thru a fuse block which should not be more than 12 inches away from the battery then to the battery connection on your amplifier the states 12V.
A similar gauge cable connected from the GND negative (minus) of the amplifier to a good clean and cleared of paint location on the chassis somewhere in the boot (secure well)
A cable connected form the blue and white cable at the back of your head unit to the remote input of your amplifier which is next to the speaker outputs on your amplifier and clearly indicates REMOTE.
A stereo RCA interconnect from the output of your head unit to the line in of your amplifier. Best if there is a dedicated sub woofer output.
You then connect your sub woofer.
If you are getting power to the amp, try this....Find a small speaker, unhook your sub and wire speaker to amp. Turn on your system at a low volume....If the other speaker is playing through amp, then your sub is shot.....If the small speaker doesnt work, then its either your channel is gone on the amp or the rcas have quit off off your head unit.
if u have the amp bridged un bridge it. chack an see wat the ohms are on the subs an make sure the amp is stable to carry the ohm load..if u have 4ohm subs one sub per channel then u shud be fine that wud make the amp see 4ohms but if u have dual voice coil subs it cud be the configuration of the subs..here's a link on how to wire subs hope this help..http://mobile.jlaudio.com/support_pages.php?page_id=145
The JL Audio 500/1 outputs 500 watts RMS into a load from 1.5 to 4 ohms. Whether your subs have 2 ohm or 4 ohm voice coils, they should be wired in series and the subs paralleled to the amp. The final load to the amp will be either 2 ohms or 4 ohms, both of which the amp can handle. If you parallel the voice coils and then parallel the subs, the final impedance will be either 0.5 ohm or 1 ohm, both too low for the amp.
You can wire each sub to a separate set of terminals or both to the same set. The terminals are connected internally. It doesn't matter which of the +'s or -'s you use.
Your subs will share the amp output. And if you are not careful, you'll end up blowing them. The amp puts out 1300 watts RMS at 2ohms, the subs have an RMS power range of from 75-350 watts, and you'll be driving them with 650 watts each. A better power match would be to series the subs to present an 8ohm final load. This will reduce the output power to a level the subs can handle. Or you could buy 2 more 12.1's and connect them series-parallel for a 4ohm load and each sub would still be getting 325 watts RMS, just about the maximum they are rated to handle.
Hope this helps.
Some older Pioneer radios require you to connect the Subwoofer RCA to the rear output on the back of the radio and then you have to turn on the subwoofer in the menu on the radio. What model Pioneer radio is it? Also, make sure that the RCA plugged into the amp is on the input side, not the output side.
When you say the 40 Amp fuse blew. Was it your mains battery fuse or was it the fuse on the amplifier? If it was the fuse on the amplifier then you may have hurt the amplifier. The Kenwood KAC-8101D is a 1000 Watt monoblock amplifier. Therefore if you say that 1 of your woofers is not playing, then it is almost certainly blown if you are sure it is connected correctly. Try disconnecting it and only running the woofer that tries to play. If this woofer is still working correctly, you will notice a drastic drop if the sound of your bass. The reason for this is because you have changed the impedance load on your amplifier due to the fact that the other woofer is not working. Have your working woofer checked and replace the faulty woofer then you should be banging again.
