2:28 seriously a SPIDER?!😫😫😫

[@amad27]

yes, one of speaker driver parts is "spider" shorturl.at/empBK

[@Quetzalcoatl0]

250w be really pushing it.
I give it no more than 100w sustained.
Sadly, the budged pre-build car subs are kind of crap and it's full of 1000 WATTS of them.

[@nicoastylehifiman]

Haha i remember i have jbl gto 1200b in my first car in 2005 2006

[@sofianelmoussaoui2926]

There is Also worse on 12 inch i have an active 150w rms 12 inch bass tube .

[@sashanash2200]

250w RMS 😂

[@sofianelmoussaoui2926]

There is also worse on 12 inch i have an active 150w rms 12 inch bass tube but it sounds nice the only drawback is distorsion at high level due to weak amplifier

[@Jonathan_Doe_]

They can take more. Someone hit one with 1000w, in free air, no enclosure, and it took a couple of minutes for it to die.
They’ll handle a 500w rms amp playing music all day, which will mean peaks of around 700-800 watts, so they weren’t bs’ing that massively. They’re also pretty efficient, so you don’t need to hit them with many watts for things to get loud anyway.
