    Custom RCA to 1/4 mono subwoofer cable ?

    I want to make a subwoofer cable with a RCA connector and a 1/4 mono plug. I am planning to use a old MonsterBass™ 300 Subwoofer cable and use the one of the RCA on it and cut an end off and solider a 1/4 mono plug on the other end. Now the question is what a good 1/4 mono plug that will fit on this cable and should I even use the monster cable or get a different cable? I all ready have two of these cables one is in great condition that I dont want to chop up but the other is not even being use and has 1 damaged rca connector anyways. Any Ideas what do you guys think. Here's a pic of the damaged RCA if you want to see.

    'Should work fine. You could also solder on a new RCA and use an adapter from Rat Shack to convert to 1/4". Connectors vary in the size of their sleeve/strain relief, so make sure you get one with a big enough "hole" to accommodate your cable. This Cardas beauty

    from Welborne Labs should be good. For something less pricey, check Parts Express or Markertek.

        RadioShack has one that works pretty well in a pinch if you have a local store. I built the same configuration cable and their 1/4" plug worked well. It has a good size opening that should accommodate most any cable.

          Yea you were the one who got me thinking of doing this wire. You did not have very good luck with a rca to 1/4 adapters did you. I think I might be having the same issue. This is for my Ep1500 amp powering a RL-p15 and It just seems like I need to turn up my sub out to get a good single no matter where the amp is set. It does sound pretty good right now but I figured its worth it to try and see if it helps. What made you make your own cable, what was your system doing that made you think of doing it?

            You are right, I didn't have good luck with the adapter - many people use them, so I'm assuming I just got a dud.

            This wasn't my first DIY cable project, but I chose to build one in this case because I wanted a specific configuration and the cheapest option was to build. I bought the cable from PE (it's 2 conductor, shielded) and the terminations at RS (I already had them lying around, otherwise, I would have got them from PE also). I have the shield floating on one end, grounded on the other.

            I use the cable (or will when my RL-p15 gets here on Monday) for connecting my FBQ2496 to the EP2500 amp.

              Jerm, I made a custom RCA - XLR cable for my Feedback Destroyer, and although some of it was pretty fiddly work I was happy with the result. I think going 1/4" to RCA should be a little easier because you're not going from balanced to unbalanced (I could be wrong), but just test your connections before you solder and you should be in good shape.

              Here's a link to my cables if it's any help: http://ca.geocities.com/ojbartley@ro...les/cables.htm

                Markertek has about every kind of cable you can imagine at reasonable prices.

                  Yes, the physical connection points are straightforward in his case - a little more so than for a XLR to RCA cable (still no big deal, just have to pay attention).

                  He is technically still making an unbalanced connection as you did...

                    What do you guys think of using 60%tin 40% lead solder to do this with? Will this be fine I ask because I have 2 1lb. rolls sitting here and would reather not buy a new roll of 4% silver content solder for just like 2 dots. Or I have some 50%tin / 50% lead but it seems that most of the good silver stuff is closer to the 60/40 what do you think

                        So here it is My finished RCA to 1/4 mono subwoofer cable. I got to say it did just what I thought, I now get a better single from my receiver. I no longer have to set my sub out to +5 or more to get good bass it is now strong and thick at -1 or 0 on the receivers sub output setting :B There is a nice improvement from what I had before using a rca monster cable subwoofer cable and one of these



                        Maybe I got a bum adapter or something but regardless the case I'm never going to look back. And a Thanks to Owen Bartley for the Techflex idea. I had some left overs from my PC project that I would have never thought of using for this.

                          I have really got to stop going into my local dealer. Everytime I go in I come out with something new. Just not right. Last night I picked up a new Paradigm PS-1000v4 sub and had to get a cable. Went into my local Future Shop and the had a 12ft AR Master Series MS202 RCA to RCA video cable for $30CDN....

                          I have a pretty hefty bandpass box with two 10"s that I'm currently using for my sub. It's a box mostly meant for car audio competitions but right now it's filling in for HT duty until I get something else built. It has two 4Ω drivers and I can wire them however I need to (they are arranged...

                          Hi all,
                          I thought this was so simple! optical being digital should be better than analog RCA connector!! Well, seems not to be the case... atleast for stereo listening

                          My setup is

                          12v trigger can I use a stereo cable 3.5mm 1/8
                          by misterdoggy
                          I read in a few threads that some people said you can use a 1/8 3.5mm stereo jack instead of a mono, cable as a 12v trigger. Is this true or will I blow up my Krells as I haven't found a mono 3.5 cable yet here in France
