Hello, is it possible to fit JBL S3-1224 to this sub enclosure?

Asked by: Martin M
Hi Martin The CSX-1400BP is a complete Bandpass subwoofer. We would not recommend to replace the woofer that's already inside the CSX-1400BP.

I have a pioneer d9601 which is 500rms at 4ohm load would sub be ok for this amp as I hear jbl subwoofers can take more clean power if run in correctly

Asked by: Mark050472
Hi As long as you don't push the amp to it's limit ( to the point of clipping ), there should not be any issue

Hi there, I didnt receive 12 V pigtail wire for the led lighting. Is it fine to make a connection from amp turn on port to the subwoofer ? Is it necessary to ground it as the amplifier has ground wire connected to it.

Asked by: shah
Hi Thank you for your question Yes it is fine to make a connection to the amp turn on port. you also need a ground connection or the LED light will not work. Have a nice day.

Hi, My LED lights not illuminating ,lights are working but its low light why??

Asked by: shaur bjd
Hi. We cannot answer your question here. If you have connected 12 Volts to the socket as indicated in the manual, it should light up with the intensity that was planned. How much that is, and whether it is enough is another question. You can contact the helpdesk to seek further assistance, of course. Contact details are found on the JBL web page, under Support.

Does the sub box have a access panel to replace speaker

Asked by: Mark050472
Hi. Access to the speaker must take place through the opening that is available when you remove the plexi window. It takes some dexterity, since space is limited.
