I have a Korean JARGUAR SUHYOUNG PA-203XG stereo mixing amplifier. I can find any label on the back of it to tell me where to hook up my power subwoofer to this amplifier. Please help! Thanks


The unnamed sub itself would dictate what you need to feed it.

Many self-powered subs accept either Line Level or Speaker Level inputs.

You should look at the manual that came with your sub.

Should it need Line Level, you could replace those jumpers with RCA-cable splitters and share that signal with the internal amp and the Sub amp. If the Sub Amp accepts Speaker Level input, use that.

Sub cutting out


Check the 12v wire running from the battery to the amplifier. Also the sony explode is a garbage subwoofer compared to the Alpine.. sony (they say 1200w max but its more like 100w to power the thing) Amp could be going. Is the amplifier hot when running. If there is a burnt smell comming from the amp, its the amplifier

Amp powers on but sub does not come on


I would double-check your RCA's on the amplifier. You should hear a thud if you unplug them. If not they are either not hooked up or defective.

KAC-9102d no sound, Amp powers on but no sound to the subs.


If the sub isn't working, you won't get a pop. All you need is a small speaker. Don't need a sub, you just want to test the sound. I recently blew 2 subs, no smoke, no smell, no sign of being blown. Absolutely nothing from the subs.... In the past my sub locked up. You can take your sub out of the box and hook the + and - to the battery to see if you can get the sub to pop there. I believe a small box will push a sub into a deep excursion to the center of the cone. I have 2 lanzar VW12D's that just quit. I hooked a 6 x 9 up to my amp and low and behold I had sound! Try that and see what you get...

One speaker is working more than the other


I would replace the wire your sub is hooked up to and try hooking up the sub that was sparked to the opposite channel on the amp to make sure the amp is not the culprit. Also switch RCA cables L to R, R to L
