Hello, can someone help me, i want to know how to connect the wires if i want to use 2 channel instead of 4. THANKS IN ADVANCE!!!!!!!!!!!!!!

2 wires plus ground needs a stereo 1/4 plug. Don't know Mark 4, but Mark 3 has 2 button fs with 3 wires plus ground. Schematic here: http://el34world.com/charts/Schematics/files/peavey/peavey_mark_3_bass_with_pa.pdf
shows 3 wires plus ground. Stereo plug does not have enough connections, only ground plus 2 wires.
Count the pins of socket and find DIN plug with proper pin-out for socket. Search google for DIN plugs.

You would want to bridge 2 of the left channels and 2 of the right channels, essentially combining the power output of the amp.

This article should help you out:
http://knowledge.sonicelectronix.com/car-audio-and-video/car-amplifiers/how-to-bridge-an-amplifier.html

Essentially you will just be using 2 channels (left, right) instead of 4 (front left, front right, rear left, rear right) essentially combining the power of those outputs. You'll want to check the amp to see if it tells you which of the outputs should be used for the "bridged" method.

make sur you are not in phantom mode for the center channel issue. The rear channel circuit could have a connection problem off the voltage driver ic. Larry's Electronic's [email protected]

Hello k_rabbit89,

A 4 ohm DVC sub can be wired in series like you described for an 8 ohm load or the voice coils can be wired in parallel for a 2 ohm load.

If your 2-channel amp isn't stable down to 2 ohms when the channels are bridged (most 2-channel amps are only stable to 4 ohms when bridged), you do not want the voice coils paralleled. The amp will overheat, go into protection mode, and eventually fail completely. A sub with 2 ohm voice coils would be a better fit. That way, you could series the coils for a 4 ohm load and the amp would operate OK with the channels bridged into that load.

But anyway, for the best power from THAT amp to THAT sub, your best wiring solution would be to wire each voice coil to a separate channel. The problem with that is that the signal to each coil needs to be EXACTLY the same or you will have one coil trying to move the cone out while the other one tries to move it in. You can closely approximate identical signals on the output side by using the same input to both channels. Do this by using only one RCA connection (either right or left channel) from your head unit and split it with a "Y" cable.

Hope this helps.

Hello canelo63,

Your question appears under the product listing for the Dual XPA4100 but the in the text you say the amp is actually a Jensen, so it's not possible to provide specific connection information.

But most bridgeable amps can be connected to a single subwoofer and the other two channels used to drive a set of regular speakers. I'd connect the front speakers to channels 1 and 2 and wire the subwoofer to the bridge connections of channels 3 and 4. On the XPA4100, the bridge terminals are the first (negative) terminal on channel 4 and the last (positive) terminal on channel 3.

Hope this helps.

I would connect the 4 speakers to channels 1-2 in stereo with high pass filter. Bridge the sub to channels 3-4.
A thumbs up would be greatly appreciated if this answer is helpful to you.

Hello ace_sterling,

Not knowing what you have the SPL-620 driving or knowing how you have it wired, it's rather difficult to determine if it's wired "wrong".

I show the SPL DK2-620 as being a 2-channel amp with 150 watts output at 4 ohms, or 180 watts at 2 ohms. Even if the power is somewhat overrated, it should provide more than enough power for a set of standard 2-way or 3-way speakers, or component speakers with a separate crossover.

Powering one or more subs is another thing. You would get sound, but the subs would not be very loud. In bridged mode, the amp is only stable to 4 ohms. So if you are trying to power 2 4-ohm subs, the best connection would be 1 sub connected to each channel. If you are powering only 1 sub, then the bridged connection would be best.

Hope this helps. If it does, please rate as "FixYa".

Hello,

The Jensen XS1010 is a 4-ohm sub and should work properly off of the outputs of most any single channel monoblock sub amp or off a bridged 2-channel. You did not say what brand or type of amp you intend to use, but in any case, there's only 2 wires to connect to the sub, one positive (+) , the other negative (-). Simply match them up with the positive and negative on the amp speaker output and you are ready to bump.

Here's the link to Jensen's website:

I'd recommend downloading the XS1010 manual. They recommend an enclosure with at least .75 CuFt internal volume.

Hello huko,

I see from your profile that you are in Bulgaria. Assuming that you are using the European PMR446 version of the Uniden radio in question, the channels / frequencies should be;

1 - 446.00625 MHz
2 - 446.01875 MHz
3 - 446.03125 MHz
4 - 446.04375 MHz
5 - 446.05625 MHz
6 - 446.06875 MHz
7 - 446.08125 MHz
8 - 446.09375 MHz
So, to operate on 446.09375 MHz you would chose channel 8.

If your radio has more then 8 channels, then you may have the U.S. version of the radio which operates on a different set of frequencies and does not have a channel that corresponds to 446.09375 MHz.

Best Regards,
Ken
