Subwoofer works with Left speakers, not with right

[hyde]

Is this the right way to hook up the subwoofer or should I hook up both L and R and then wire them to a single connector and then split before the amp and hook it both L & R combined?

Did you get a new sub? Are you using speaker wire and not RCA to give the amp signal?

If youre talking about splicing the L and R speaker wires together then running them into the amp I wouldn't do that. Doenst your connector have 4 wires coming out of it?

Get a subwoofer with dual wound voice coil it will have both left and right inputs for you. Putting left and right positive then left and right negatives together can work but is not a good idea and would have to be after the amp not to it - oh wait just get a bridgeable amp for the sub they have both the inputs and then bridge it to the single output!!!! Yeah do that don't do what you are doing.

Thanks and welcome to the site!
JeepJeepster answered me on a PM with some information, but I just wanted to point out that I do have a bridgeable amp, and in fact my output is bridged so I can get 150W out of it.
My H/U has stereo RCA dedicated sub output (both L and R). So what I will do like you said, I will run the L & R to amp directly, and I will keep the bridged output, and will report back if I see any improvement on bass response.

Ya won't get better bass response but will get more powerful bass from it. Bass is usually distributed evenly to each channel in the studio mix anyway so even if one channel was out you should still have decent bass. Rather than like a 40 watts of input with both channels you would'a had half that as input only with one side working, and then just turn up the gain whatever it takes but bridging is the way to go so you don't combine L/R into each other going in the amp.

I installed a soundstream 5 channel amp, with two 12 inch Pioneer shallow mount subwoofers. The 5th channel is subwoofer dedicated. Both subwoofers are 4 ohms, but are wired in parallel to produce 2 ohms.

If you have one subwoofer, and the amp has LEFT and RIGHT outputs:
- Take the LEFT channel + and the RIGHT channel - and connect it to the subwoofer's + and - respectively.

- cap and stow the LEFT channel - and the RIGHT channel +

Amp has 4 channel speaker line output. It is wired as you said, bridged. I did not cap anything, I simply didnt wire anything on the remaining posts. But I will hook up the R to stereo and amp, and will report back.
