SOURCE: KAC-9104D output terminals

ok i have the same amp and 1 2ohm dvc sub and was woundering the same thing but from futher research and askin sum xsperts. What i found out is that it is only one channel and even tho there are 2 (+) and 2(-) they actually connect inside the amp makein it one . so if u wanted to wire sumthing parralel u wouldnt have to hook wires from one coil to the other on the speaker , u can just hook it up to the amp. so basically both +'s and negatives on the amp are actually one within it so all the power if you only use one set of them and if u wanna add more subs its just easier to add to the amp by using the xtras .

There are 2 input ports on the sub woofer. How can i connect them to mono amp


subs usually allow a bridge where you connect the mono positive to one side positive and the mono negative to the other side negative. Does it not mention this in the instructions? If you don't have the instructions, try it. It can't hurt anything, but use low volume when checking. If you want to verify the bridge before hooking up, use an ohmmeter to look across the positive on one side to the negative on the other. If one combination is open or more than 8 ohms, try the other set of positive and cross-negative. OK?

I have a ts-w307d4 pioneer sub woofer and its a 4 ohm sub that has 4 terminals on it 2 red and 2 black how do i wire this sub to my amp i have a sony 1200 watts stereo amp and my sub is a dual voice coil...


conect one of the positive terminal from the sub directli to one chanel of the amp, and do the same with the negative,and do the same with the others terminals from the sub conect to the other chanel

What kind amp should be use for ts-w307d2 subwoofer speaker?


Nice sub, i have 2 308d4s in my car. Okay this sub is a dual coil 2 ohm. so to get best bang for your buck you'll want a 2 channel amp and bridge it. Your sub is 400 watts RMS, So you'll want an amp that has the same rating. I'd recommend the pioneer GM-5400t. Then wire your voice coils in parallel, and bridge your amp, you'll get 380 watts RMS, which is perfect for this sub. If you have questions on wiring or anything you can just ask. thanks, i hope this helps

I need help installing a 4 Channel Power Acoustik Amplifier to Two Pioneer Subwoofers. I hooked up the power wire to the positive battery terminal in the engine compartment. I then cut the power wire and...


You are doing right on what you described. I really like to work with a clearly described what involved in an issue.

Now we have to use a Voltmeter to check if there is power to the amplifier. If there is power to the amplifier terminal, then the problem is at the amplifier, not the connection. Let check it out:

1- Turn on your Kenwood radio, make sure to hear sound from your regular speakers.
2- Turn remote control knob to the mid level between min and max.
3- Measure the blue wire where you spliced to ground to see if you have 12V, if it is not then the problem is right there.
4- Measure the Red wire power from the Amplifier to ground ( the bolt that you connect the negative power to see if there is 12V, if not trace back to the Fuse that you inserted between the positive terminal of the battery and the wire going through the firewall to correct it.
5- If you have 12V at step 3 and 4, then you have a defect unit, return it to the manufacturer for a replacement.

I have the pioneer sub and a sony 600watt 4


it has a detector that kicks in it will usually shut off your amp and it keeps you from blowing your amp the speaker may have to much power and amp may not push it it will start to protect itself

Two terminals? bridging theory?


Hello again jm129852,

Having two power and ground terminals allows you to run two smaller wires instead of one big one. It's a convenience. No, you do not have to use them both. They are connected together inside. Yes, you should still use a single fused battery lead. Connect the big wire and fuse holder to the battery and to a distribution block and run the smaller wires from the output side of the distribution block.

When you connect the outputs of a two channel amp to two separate speakers, each speaker gets the power produced by it's channel only. If you are using only one speaker, and the amp is rated to operate bridged, then the speaker will receive the power from both channels, typically twice as much. You do need to be careful when using bridged mode because many amps will only operate safely at a higher impedance when bridged. For example, when operated with both channels connected to separate speakers (not bridged), it may be stable to 2 ohms. But when you connect both channels together (bridged), it is only stable to 4 ohms. Usually, the specifications will tell you the lowest impedance at which the amp should be operated. The specifications for the current RF Punch 500.2 are like this: 125 watts X 2 at 4 ohms; 250 watts X 2 at 2 ohms; 500 watts X 1 bridged at 4 ohms (4 ohm stable in bridged mode). You would NOT want to connect two 4 ohm subs in parallel to this amp in bridged mode. It would result in a final 2 ohm load and the amp would overheat and fail. One 4 ohm sub would be OK, and it would receive the full 500 watts as stated in the specifications. You could connect four 4 ohm subs, two each in parallel to each channel, and the 2 ohm loads on each channel would be OK. Or you could series two of them together for an 8 ohm load, do the same with the other two, and then parallel the two 8 ohm loads for a final impedance of 4 ohms and connect them into the bridged terminals. With DVC subs the connection possibilities get more complex. There are many good impedance calculators online that can help you determine the best wiring solution for various amp/sub combinations. I like the one above at the12v.com web site. Rockford-Fosgate also has one which allow you to select the a number of subs (up to 4), their voice coil configuration (single or dual), and the voice coil impedance. The RF calculator then shows you what configurations are available and what your final load impedance will be.

Hope this helps.

How do i hook it up


On the Sub you have 4 connectors, 2 for each voice coil... Run a jumper wire from One side of the sub to the other. Positive to negative so that now you have one set of connectors free. Doing this will make the sub able to handle more cause you're using both voice coils. Thats how i've always hooked mine up when i have duel voice coil and they always last a long time. If you're gonna bridge the amp, make sure its turned down for about 5 or 6 hours to let the sub break in.

Is Sub Underrated for my Amp?


fuses wont restrict the current flow the amp is way too much for that sub. it may not have damaged that sub yet but it will. you might only need a 100 watts rms too run it.but you will need sowe where about 2000 watt sub too run off that amp

2 Subs running together


If they have the same impedence (like 4 ohm) then you should be able to run two different model number speakers as if they were the same model number. There might be a slight difference in the way they sound, but I would not expect it to be enough to be noticeable. Good luck.

How to


First of all, make sure your amp is bridgeable. There are a few ways to bridge subs. series: hook one wire from the negative on the left amp output (or whichever is labeled on amp for bridged)to left sub negative. left sub positive to right sub negative, then right sub positive to the amp positive output.(like a big loop through both speakers) parallel: both speakers get their own set of wires, both negatives go to the bridge negative terminal, and both positives go to the positive bridge terminal. Series-parallel: A combination of the two. say two speakers in series, and one hooked up alone, but all to the same amp outputs. Bridging your amp/speakers basically lowers the resistance of the circuit and makes more current flow, more power, louder, harder hit. In series, it also makes both speakers do exactly the same thing, instead of "stereo sound" or L/R differences. What you're probably looking to do is Bridge in parallel. That will drop the resistance of the circuit the lowest, allow the amp to put out the most amount of current to the speakers, and allow your bass to hit the hardest. If your amp only has one output, hook up the same way as above. Just see what resistance your amp is stable down to. If down to 1 ohm, no worries. if stable only to 2 or 4 ohms, you may want to bridge in series to be safe. That will cause the resistance to go up, and will not pull as much current through the amp. The whole time, just remember Bridgeing and higher current mean HEAT so watch your amp. I hope this helped.
