Sorry I got it mixed up between the RMS stuff.

So, if I got this...

http://iweb.alpine-usa.com/pls/admn/...=104&p_main=10

and...

http://iweb.alpine-usa.com/pls/admn/...=120&p_main=10

That would be the perfect match because the amp does 40x4 and those speakers are 40RMS?

But then this HU...

http://iweb.alpine-usa.com/pls/admn/...y=45&p_main=10

Does 50x4, so I wouldn't need the amp if I got the Type-S speakers?

And if I got the sub would a mono amp be okay?

Like this one?

http://iweb.alpine-usa.com/pls/admn/...=140&p_main=10

For this sub:

http://iweb.alpine-usa.com/pls/admn/...=150&p_main=10

Or would I need a stronger amp and or stereo one instead of mono?

Thanks again man!
