Thats a sweet idea...
what would be better, 3 12's (TYPE R's)
or 2 12's and 1 (15" TYPE R also, and seprate freq's.)
(so buy another 12, or buy a 15)
and, what about porting it through and into the car, what would that be like, i was thinking of porting into the middle of the back of the seat (in the middle seat) a big (but properly designed port) or a couple even.
I thought of porting through and into the rear deck, but think this would be bad for the rear glass due to the intense SPL. and tornado like winds!
(*talking about porting the box into the car, not porting the rear deck , (thats already done to help vent the trunk*)
I want it to be tight though so I am leaning once again to sealed, (have the ported box now, kinda miss my 4 10's on tightness)
- i was thinkin 2 sealed 12's and 1 ported 15 (so the 12's could be sealed, seprate chambers, and the 15 in a ported chamber between the 2 12's
-any Ideas on the 180 degree mounting, meaning 2 facine out, 1 facing in (just wire out of phase? right)

Cool thanks Brando, I am going to go with 3 12's in sealed (3 separate chambers)
I want to show off my huge magnets, the Type -Rs are heavy duty.
I think I am going to make a straight box with 3 12's all in a row, thinking about having one in the middle inverted. or the 2 outside ones inverted.
duno..

Hi All,
Electronics, as used in sound systems, have changed considerably since I dabbled in the hobby, but I don't think the need for free movement of cones have.
Are the above mentioned sealed enclosures actually air tight, or are they just called sealed?
If they are airtight, what changed?
Regards, Norm

Yes, they are air tight, all seams are caulked. Not sure what you mean by what has changed? Sealed enclosures have been around for quite some time....
Here's a little info to read about them...

Funny how much I've forgotten over the years.

Quote: Yes, lower resistance equals more distortion, but with subwoofers...you're not gonna be able to tell much of a difference...especially in a car. ok, but how about blowing the subs, i've already blown 2 of these a long time ago, then i changed the freq to 35hz on my EQ (instead of 90, or 110)and down for the subs. QUESTION: is this true? Quote: If you decide to bridge the amp, you have to be even more careful. Bridging, or combining, two channels of an amp will make the amp "see" half the impedance of your sub system. So if you have your 2-ohm-stable, two-channel amp bridged, you can't put anything lower than a 4-ohm sub setup on the bridged single channel.
So if i bridge my 1 ohm stable amp onto say 2 4ohm subs in parallel (2ohm)
then when bridge my amp onto that, it will see half of the (2 ohm) and equal a 1ohm load??
That doesn't sound right to me, this is the first I have heard of this??

werd.
People are stupid and put the gain past halfway, generally this is a bad idea.
I guess you could be killing subs by overloading them mechanically such as throwing 3000 watts on a 400 watt sub dont expect it to last to long.
