Hello everyone, I have a quick question, can a subwoofer wear out and loose power? I feel like mine barely sounds, it does move, its not seized, I have turned up the bass on the stereo but I don't get the same "boom" from the sub like in my 08 ES350. I have an 04 LS430. Maybe it's the amp that it's not producing enough power? Could I get a lower ohm sub so that it gets more power? If the problem is the amp, I'll just leave it like it is, but if it's a quick, cheap fix like a 60$ sub, I'd do it.
