When I play music loud with the bass up high the subwoofer starts to make crackyling/popping type of noise.
Check any wiring coming or going to the subwoofer. It sounds like it could be a loose connection. Is there a LFE or bass boost knob on your subwoofer? Does turning that up/down cause the crackling (if it exists). If so, you could use some tuner cleaner to clean the contacts on the potentiometer knob.
If the crackling is on the subwoofer only, it might be damaged from bottoming out. See if you can remove the baffle or grille covering the woofer and inspect for visual problems. You can also try to lighly push in and out on the subwoofer to hear if it makes any scraping sounds. If so, it is definitely damaged and the driver will have to be replaced.
My subwoofer Popping qhen I turn it up what can cause it?
Tks Mike, this worked for me. I put some wd40 oil and a little Isopropilic alcohol inside the potenciometers and turned It for both sides many times and the popping noise was over
you're looking for a loud subwoofer you'll need to consider sensitivity,
enclosure type and available power. You'll need to start with a subwoofer with
a high efficiency (sensitivity) rating housed in a ported or band pass box.
Power the sub with an amplifier that has a power output that is within your sub's recommended power range. You'll achieve the slam you're listening for. Using an amplifier with a bass boost control can also help.
