It's not backwards 1 octave above tuning the pressure in the port is equal to the pressure in the enclosure meaning there is no movement. So it is acting just like a sealed enclosure would. If you are only concerned with SPL then yes you can tune high but .....

Its going to depend on how well they are built, volume, port area and tuning. 

LOL I totally misread his post. the 2 tens should be louder on same power as a 12, especially if they are in similar enclosures (both sealed or ported).

The E has 250 watts RMS and R is 500 rms. the R has more Xmax. All in all the R will have the potential to get louder. 

Again it does not have to do with how low the bass is but the response of the system and how a ported enclosure acts. Right now sealed my IDQ sound good on metal and roll off at 30 Hz. When I go ported they will have almost the same response but a little more output from 30 to 45. above that...

Don't listen to those people...lol. Its not about how low your music goes but the response of the system. Tuning that high you will most likely be +6 at 50 Hz and +3 at 55 Hz. Its going to be  steep peak which will be pretty undesirable from a musicality stand point. Where as if you tune lower...

The Demons look great.

So? a ported enclosure is prety much acting like a sealed enclosure an octave above tuning. So if you tune to 40 Hz at 80 hz you would be very similar to a selaed enclosure. Kick drums and bass shine from 50-80. I would recommend tuning lower like 30 hz. With a decent driver you would be...

Is the voltage regulator separate from the alternator on that vehicle? If so I would look there.

Why would you not tune low for metal?? 40 Hz is going to be nasty without alot of eq.

The E series are solid entry level subs. You would not be disappointed in the Demons they are not entry level. As for JL the w3 is not really designed for out put they are more for sound quality. that is not to say they would not have decent output. the Daytons would be on par with the W-3's...

If considering the JL w3 I would do the Dayton HO's for a lot less. They sound just as good.

Are you trying to set the gain on the amp or are you asking what the voltage should be coming from the battery?

the rear speakers are okay as long as they are playing a full range signal. they are doing a lot of funky processing on newer cars OEM systems.

Just because the stated frequency response says they can go down to 37 hz it doe snot mean they will playing in a shitty enclosure like a car door you will be lucky to get down into the 60's.
