  • Fantastic!!!
Does EXACTLY what it says. I used to build these myself until now that I can buy them at this price!!! Perfect for any speaker-level to line-level conversion. They even have "transformer" isolation!!! Fantastic product, I can't say enough good about it!!! I have bought four of them so far. Have used them in automobile applications for feeding line-level to full-range amps and subwoofer amps. These DO NOT have a subwoofer filter in them, they convert the ENTIRE audio range. A subwoofer amp will have it's own filter in it so that won't be a problem unless you are using a regular (non subwoofer) amp as a subwoofer amp. In that case, you are going to need a low-pass filter to filter out all but the subwoofer frequencies. ... show more

  • Good product
Good quality, easy use it worth the price, we had to buy another switch to connect the wires but it has a good sound. I highly recommend it.

  • Worked fine, but note they've revised these from those pictured
I'm using this to pull speaker level output from a set of computer speakers to a small repurposed subwoofer. They work fine for this application, but I've no idea how well they would work in higher fidelity and full range output. One thing to note is that the pictured product clearly has an electrolytic capacitor across each of the channels. My assumption is this is done for DC blocking which is generally a bad thing to subject your speakers to. However, this can impact frequency response. My example instead has resistor where the cap used to be. I assume they changed it because they were unhappy with change in the frequency response. ... show more

  • Best Line Output Converter Out There.
Literally the best converter I've ever used. There is not 25 silly little extra wires on this thing, there is left speaker and right speaker positive and negative. That's it. No power, no ground, no "remote" which is extremely weird for a line output converter anyway, nothing other than positive and negative. I bridged my left and right together also since I'm just running one rear sub. Output is clear, no distortion, no weird clipping, no frequency dead spots, it's awesome. And for $7 you get two of them. ... show more

Garbage, neither one worked.

  • Plus and minus. Where are they?
I don't think I am asking much to have the + and + labeled or documented with the part. Or am I just expecting too much?

  • Great product for the price
The converter is just what I needed especially in a package of two. I have a system in my truck and in my SUV each one works great. Had no problems. Was easy to connect from my factory head unit to add an amplifier and a 10 inch woofer just for little extra base. Great gain control
