2 RCA's coming from amp into radio's single subwoofer output RCA?

very good ! there is nothig wrong with your system, buy a stereo to mono RCA jack (Rs10/-) and connect the subwoofer (if single coiled) L+ & R-- of your existing amplifier. NB: Please go through the manual of amplifier
.

Connect front the sub out (single) on the amp to one of the rca inputs on the sub, This will work reasonably well but to make the most from the sub buy a 2 rca to 1 rca cable and use it to connect both rca inputs on the sub to the single output on the amp

If your indash radio does not have RCA outputs, you can do two things. You can purchase a line level converter and hook it to one of the rear speakers. This will allow you to tap into the speaker wire, then convert the signal to RCA. Then you plug your RCA cables in there. The other (my recommendation) is to purchase an "add an amp" wiring harness. This harness will install between your radio and vehicle harnesses. It will have RCA output and remote wire. Then you run those back to your amp and there you go. You can find these at the scosche or PAC websites. You can also try www.crutchfield.com

Hello there this subwoofer has a built in crossover variable from 50hz to 150hz which means that any signal you feed it the sub it will ignore anything but bass anyway.

As for the connection it is made quite difficult if you don't already have an amplifier powering your other speakers, usually home cinema amplifiers have a low level pre out for subwoofers, for which you would just need a phono to phono cable.

However if it doesn't and you have any type of amplifier with at least 2 separate left and right speakers you can connect the wires from these into the subwoofer and it will output the bass from these 2 channels.

Another option is to use a mono to stereo (2 to 1) phono cable where the 2 connectors at one end connect to a tape or record output on your amplifier and the single phono at the other connects to the subwoofer, the same would go if you have a red & white phono (RCA) output on your TV you could also use this to power the sub, in the worst case scenario you could use a single to single phono or rca cable to connect one of the output channels (left or right) on your TV to the subwoofer however this would mean that the subwoofer would only output bass from either the left or right channel.

Hope this helps

Kind Regards

First of all get yourself a Y-LINK cable. (single male RCA on one side/ double female RCA on the other side) Connect the Y-LINK to your head unit sub woofer output with the stereo RCA that leads to the sub woofer amplifier. Now you are connected to the correct output. I do not know what head unit you had connected before to base your comparison, however there is a output voltage difference from one head unit to another, (1.2V, 2V, 2.5V, 4V, 5V) and that is what determines where the gain on the amplifier should be set to. Always match the headunit output voltage with the amplifier gain control to be the same. It is not uncommon for some entry level units to have a single sub woofer output. dreamsystems

it has 3 pairs of rca outputs, one pair for the front, one for the rear, and another for the subwoofer. the other sub preamp output is not needed to run to your amplifier.

For better sound quality, buy an RCA Y splitter cable (single male connection to double female connections), and run your regular pair of rca cables to the amp.

#1 you need a ground loop isolator to put on the RCA cables. that should fix the problem... put one off the amp leading to the sub also cause that will also fix it these gorund loop isolators can be picked up at any electronic installer shop.., you might be able to find them at radio shack to but i would not buy those cause they dont work as well as the better ones, i would suggest any auto alarm radio installer shop.... hope this helps you...

If you are running a set or a single subwoofer with the jensen amp than you will want to hook up the rca cord to the subwoofer rca connection on the back of the stereo unit-the other rca outputs are there in the event that you want to run a 2 or 4 channel amp to power the speakers that are generally located in the doors or back deck-with that set up properly you would still be able to adjust the balance and the fader just as though you were powering the speakers with the deck. Pug the free ends of the RCA cord into the input rca receptacles of the amp- the stereo now will feed a signal to the amplifier that only contains bass - good luck

Subwoofer signals should be MONO - not stereo (hence the single Component out on the radio)
Only use one RCA to send signal to your amplifier.

If you use a Y splitter - the signal voltage will be cut in half - deteriorating the quality, and therefore amplifying "dirty" signal.
