lol I Love how I unintentionally start arguments... hey guys here is a pic of what im comming from as you can see this is the reason why im going with a single subwoofer versus 2. I do listen to mostly rap but i make all my boxes custom and have so for years certian time sealed certian times ported depending on the sub really " in my experience some subs just do better in one type versus another" and im not opposed to building another if it doesnt come out right.

As for the clipping argument my general process is this ( im an electrical engineer so i have lots of cool testing tools)

1) set unit at max volume with single sine wave for no cilpping/ distortion
2) I have 3sixty so set this as well
3) amp then back down about 20-25%

**if all up to amp is not clipping then make sure there is a little room for varrying levels from differend sources i have very little problems

** i have also built a tiny little addition to my outputs which activales an led when/if ( doesnt happen often in my experience) the signal clips so then i can adjust with volume knob feature of 3sixty processor

This was more of an opinion question to all of you very smart guys on which one would match better with this amp.

I have a buddy in the airforce who's job is to set up communication towers (from scratch) and repair electronics.... he's got access to some crazy stuff too. Oh yeah... he has to make sure the base is shielded from EMP blasts... so he has a giant EMP generator. Course... he then moved to germany.... and then I moved a state south, no longer have access to all his tools.

Wish I had an O-scope... that and a clamp meter and I think I would be happy.

WoW.

Nice "showy" setup you got there.
( a little black carpet on that box goes a long ways. )


That sub setup you got there just KILLED ALL the space in your cargo area.

As much as I would love to have a pair of Type-R 12's in my Yaris, no way was I gonna give up that space back there.

You are going to have a hard time finding one sub that will equal those two bad boys back there.
Since you listen to RAP, you will definitely want a ported box.
And I don't think ANY single 10" will make you happy.
( maybe the JL W7, or a high-power ORION HCCA )

Although, it looks like your box is a sealed box, yeah?
If so, one sub in a ported box might surprise you, playing RAP beats.
I was really surprised at my 10" Type-R in a ported box.
It sounds nice with rock kick drums, but it really shines when I tried some BEAT DOMINATOR on it. The whole car was vibrating really good.
My box is definitely tuned for RAP beats, but it also sounds nice on rock music, which is why I decided to keep this setup.
If I put my Type-R in a sealed box, it would tighten it up some, but I know I would lose some SPL too. It's always a trade-off.

If you are looking to save space, try a single 10" W7 in a ported box.
That might be your solution.
