AA mayhem vs. Fi sp4

I’ve been looking around for a new sub for a while, basically a beast of a daily driver sub, and have narrowed it down to two subs, aa mayhem or the fi sp4. Found a post asking the same question as I’m going to ask and everyone was leaning more towards the mayhem side, just because no one really had any experience with the sp4. Now I found a video explaining the sp4 was made to compete right against the smd subs that steve meade uses, just a lil less power then what they use.



I have a sundown 2000saz amp. So I was wondering if anyone has experience with the sp4 yet? And if so is it worth getting or just go with the mayhem?

Also, I am open to any suggestions on any other subs also, as long as there 18” subs, just looking for one 18” sub

 
From the looks of the SP4 it isn't anything like the mayhem...the mayhem relies on large motor force whereas the SP4 has some serious excursion to it. I would imagine the SP4 does better on the lows than the mayhem.

 
Your forum was actually the one that I seen, and like you said they voted for the mayhem, but thats just because no one really messed with the sp4 when you had the thread going, thats why I started this thread, mabye someone had some experience with them and could make the decision a lil bit easier

I asked the same question too a few months ago.If you search for it you will find the thread.

everyone voted for the mayhem.
 
I don’t want to compete; this is just more of a hobby/interest that I like doing, But honestly would be better with a 2000 watt amp for going low daily? The way it sounds like the sp4 would be better, but I just want to make sure

 
You answered my question before I could ask it lol, but just want to make sure about the 2000 watts part

For a low daily sub get the sp4 if you wanna compete and need the #s get the mayhem they both sound good either way.
 
both are sick daily drivers, both need more than 2k to utilize their potential,

both will be stupid loud.. the sp is gonna want a slightly bigger box and is gonna have slightly flatter curve..

if it was a daily driver tuned below 35 I'd go fi if not go with the mayhem..
