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.

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, 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.

Moet je persé de gtr 601 gebruiken of zijn er ook andere versterkers die ik kan gebruike

Asked by: Bambinobogers
Goedemorgen, Uiteraard kan je ook andere versterkers gebruiken. Je zal hiervoor echter zelf de gegeven van de Subwoofer erbij moeten zoeken, en dan kijken welke versterkers hier bij passen. Je zal dan moeten kijken of de weerstand ( 4ohm/8ohm ) past bij de Subwoofer, en of het maximale en de nominale uitvoer niet te hoog of te laag is ( Amplification Power ). Je kan hiervoor de specsheets vinden op de produktpagina van elke versterker. Mocht je hier hulp bij nodig hebben, neem dan even contact op met onze klantenservice, dan helpen we je graag verder

Asked by: Antoincatz
Bonjour, Nous vous remercions pour votre question. Le caisson n'est pas auto-amplifié et il vous faudra rajouter un amplificateur externe afin de connecter ce produit.
