Hey guys I need to know which sub be the better sub to run on my 3k

Does anyone had these subs ?

ascendant audio mayhem or fi sp4

Are you serious?

Bro that Mayhem 12" will crush a 15" Sp4, mad deee beeez

low end extension-SP4

Sheer output-mayhem

but why not a mayhem 15?

I found a used 12 mayhem for like 300 bucks is that a deal

Depends on how "used" it is. If it is in decent shape then yeah it is a good deal.

Mayhem is my vote. Gets plenty low and is a monster on output. And for 300 its a good deal if the condition is good.

mayhem is mine as well and for 300 thats not bad for used but if the cone is broke in pretty good u may wanna try to low ball and offer 250 IMO

Please provide a lot more information so we can actually help with an informed decision.
