I have 2 12'' sonys. one blew and i wand to just use the other cuz it's still good. how do i wire the single woofer to the amp. heres the amp specs:
ARC Audio ks 300.2
Power output RMS @ 4 ohms 2 x 180 watts
Power output RMS @ 2 ohms 2 x 350 watts
Power output RMS @ 4 ohms bridged 1 x 700 watts
Transient Distortion (100 watts) <.01%
Frequency Response 20Hz - 20 KHz
Signal to Noise Ratio >98dB
Bass Boost +18db@45Hz
Crossover (Butterworth) 55Hz - 5.5 KHz variable 12dB
Fuse 30A x 3
Size 13.0''(L) x 8.0''(W) x 2 3/8''(H)

and here's the sub system:
Sony XS L120B5D

MDF construction with black carpet covering
two 12'' five-sided polypropylene woofers with rubber surrounds
4-ohm total impedance

power handling: 100-600 watts RMS (2,000 watts peak)
sensitivity: 89 dB
32''W x 16-1/16''H x 18''D1 x 15-1/4''D2

i want to remove the good sub and connect it to the amp... a also want to know how big of an enclosure to get

Is the speaker a dual voice coil speaker? If so you can wire it up a couple of diferent ways, go to rockfordfosgate.com they have a woolfer wiring wizard that can show you the different ways to wire for 8 ohm.....4 ohm.....2 ohm....and 1 ohm...I would figure out how to get the most power out of the amp in mono mode, take that ohm load from there and see if you can wire your speaker to match it.

What's the best way to hook up my jl audio 13" w 7 sub to my jl audio 1000/1 amp


the best way? hmm. i would start off with some wire. Keep in mind that you will need to separate the positive (usually red or has a stripe or marking on it) from the negative (Black usually is the common color for this wire) and hook the up according to your amps positive and negative hook ups / terminals following your sub-woofers terminals. then depending on your sub woofers Voice coils (Duel or single voice coils) yours are duel or quad coils but i\'m sure they are duel (2 of each positive and negative equaling a total of 4 posts on each sub-woofer). figure out your amps ohm load handling and does your amp run hot (1,2 or 4 ohm stable some are even less like 0.5 or lower) i would run at a 1 or 2 ohm load as that is usually standard on 1 channel amps. make sure to check your wiring and if your not sure about ohm loads just Google wiring for sub-woofer ohm loads such as 0.5 ohm, 1 ohm, 2 ohm or 4 ohm loads. also make sure your box is not sealed do to the fact they are siht and cant produce sound like a vented / ported enclosure keep the size as big as you can fit in your car or truck the bigger the better. i had one 8\'\' sony sub pounding like a 15\'\' sub real loud . Also MDF particle board is garbage it causes port noise and absorbs water

If the lights on your sub box aren't coming on it's either your ground of power wire came loose or the transformer blew. As for the subs, make sure all the connections are good, especially on your RCA wires. If your amp is getting power, then check your speaker connections. Also, make sure to turn the gain know up. The gain knob is located next to the RCA input on the amp. Let me know if this helps.

Make sure you are wiring the sub to the correct ohm's. Some amps have a protective feature that will send them into protect mode if they do not since the right ohm load. If the sub is wired correctly double check your ground wire on the amplifier, and if that if also fine then your amp will need serviced.

My xploid amp blows the fuses in the amp if my subs hit to hard and i dont know why?


It sounds like you have the levels improperly matched or the wiring to the sub woofers making an improper impedance match. Make sure you are not overdriving the amp by running the levels lower, or check if you need to rewire the speakers to get the right ohmic value at the amp. A good resource for sub woofer wiring can be found at this web site:

You need to use an amplified sub. The Yamaha receiver is only sending "Pre-Amp Signal" not amplified audio like the rest of your speakers. If your sub has a crossover built in, connect it's speaker level (wires) to the "B" side of the receiver which will send audio to your sub and it will cross it over internally. Not the best sounding, but it works. Amplified subs range in price from 200 and up. Hope this helps

Open your sub-woofer and check the continuity of your bass speaker. Chcek also the fuse of the sub-woofer amp...the fuse might be busted already.

How many svc subs at 4ohm does it take to get this amp to 1ohm stable and can you reccomend a good sub combo for this amp whether it be dvc or svc


It depends if your sub is 4ohm svc, or 2ohm svc. 4ohm would take 4 subs wired in parallel, 2ohm would take 2 subs wired in parallel. But for a amp that big, subs that'll handle it are definitely gonna be dvc. I'd recommend 2 Orion 4ohm dvc hcca's. They come in either 15in or 12in. the 15s are louder if you have the space for them. As far as wiring goes, wire the voice coils on the subs in parallel to 2ohm per sub, then wire the 2 subs in parallel to 1ohm. Goodluck and congrats on the equipment, Orion is about as good as you can go for subs and amps. just be ready to lay down some dynamat cuz this system'll bloww your vehicle apart! good luck...

Bare wire sub to single RCA jack receiver


Yes you can modify RCA cables to make bare wire tails.
If the unit has a sub o/p then you just connect up your sub bass unit to whatever the amp needs.

An RCA cable is 2 wire which is all you would normally need for sub bass speaker level signal.
It may be a good idea to eventually upgrade the wire size if you want really good sub bass as lower frequencies draw more current and so require more copper.

Please let me know if this any help, thanks for using FixYa.

Amp light is on but no power to my subs!


Hi There.

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.

Hope this helps!!
