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.

What amp should I use?


Yes they information available on them they are still around. You will need a class-D 300 watt RMS amp to run them at perfect power if i remember right they are 150 watt RMS,, 450 watt max per sub.// just never mind the max it means nothing. They are a 4 ohm sub i believe so you would want to get a 1 ohm stable amp. two 4 ohm subs can be run at 1 ohm wired in series. they are actually made by audio vox corp.to wire them is easy ill give a link to do so easy to use. and handy. let me look for some info on your sub...? Yes there is info out there here is another link. Need additional help give a shout.

Cant hear anything out of my speakers connected to djio


Are you using a Mixer as a pre-amp for this set-up? For example, I have a Numark CM200 where I have all of the inputs and outputs I need to run. DJ IO is connected to Chanel 1 and Chanel 2 Lines in my mixer. The DJ IO is conected to my computer by USB cable. In Traktor souncard settings chanel 1 is set to (3&4) Chanel 2 (2&1) also, devise set up is Numark DJ IO and in External mode. Of course the mixer is conected to my amp and speakers conected to the amp as well.

Dont know how to wire a subwoofer


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:

http://mobile.jensen.com/jensen/

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

If this helps, please rate it as "FixYa". Thanks!

DON'T KNOW WHAT WIRING KIT TO USE FOR 400WATT 4 CHANNEL AMP


well i will let you know now that 400 watts running into two subs like that will never match. You will want to run only one sub or get a bigger amp. But for that amp a standard 6 gauge power wire will be sufficient to run it. The ground wire about 4 gauge is good.

L7 wiring options


yes it should work fine i would bridge them up to 4 ohms each speaker then bridge them back bye conectin them on the amp by puting the red with the red and puting the black with the black if the amp only has 1 chanel then put both speakers red on the same positive on the amp and same with the negative now to bring the ohms up to 4 ohms conect the solid red to the black with dot with a short wire ok then the ones that are not run together will go to the amp giving offf 4 ohms and with the 2 speakers bridged together thay will reduce to 2 ohms witch means that eatch speaker will get about 600 wats of rms from the amp
