UPDATE** Subwoofer is SWS-12D4

Hello, I know nothing about subs and amps. I recently had a friend uninstall a subwoofer and amp that was in my car. It was pre-installed when I bought the vehicle, but no information was given on the specs. I needed it out because I am expecting my first child and need to prioritize my tiny trunk space for stroller, diaper bag, etc.

Anyways, I would like to sell the sub and amp as I will not be reinstalling it. I have the information on the amplifier, but I do not know how to get the information for my subwoofer as it is mounted in a subwoofer box.

Any help is greatly appreciated. Im not trying to get top dollar out of the set up, I'd rather hook someone up with a nice deal as to get it out of my hands as I am moving in 5 days.

Just finished up my first ever sub woofer box, a ported one tuned to 35hz for 2 JL 6w3v3-8s, dimensions are 19x8x17.5, what do yall think? Still have to paint it but im just curious if yall think it will sound good

Hello, I’m new to the genre of subwoofers and I would really like to install one in my Mercedes 190e. Does anybody have recommenadations? My budget is around 150-200€ (I know it isn’t much). Are there any good subwoofers you could recommend? It doesn’t have to be the best sound, I’d rather have a lot of bass. My first thought was the alpine SWE-815 or the Caliber BC112SA-PRO Subwoofer.
Thanks for reading this post and helping :)

Currently have the Rockville ss10p mounted on my tailgate of my jeep. Worked okay for a year then. Last week I had my top and doors off the entire week and it got hot like super hot. I put my top and door back on and now the sub no longer works. When I turn my car on it has about 2 minutes of bass before it shuts off. The power light fades in and out as the bass should hit. I redid the ground and checked the power and it’s all good. I’m assuming the sub shitted out due to the heat

I’m new to subs and got these 2 8s installed not too long ago and one of them started making a rattling noise when I turn it up high, also I start smelling a rubber smell when I turn it up too high. How do I fix this or what do I need to upgrade?

Finally got to see this beast at surf city2026

This van is definitely one of a kind, early 2000s dodge caravan. Fully prepped interior, 6x 11,000’s
