F-Mod! thanks.
it was totally eluding my memory there.

yeah Fmod 20Hz high-pass filter.
blocks anything below 20Hz, which prevents loss of damping for the driver.
this means no damage to the sub when it tries to hit frequencies below that of the tuned port.

3" ID ports are good for up to 10" subs
4" ID for 12"
6" ID for 15" and larger.

for the JBL amps yes, get two (2M-1F) RCA Y splitters. that will give signal to all 4 inputs, which means the input stage of teh amp gets full voltage on all inputs and the resulting output will be noticeably stronger.
http://www.knukonceptz.com has these splitters for about $2.50 each I believe.

They are crossovers.

In the FAQ it tells you what the TS Parameters are needed.

Also if the given TS parameters dont match the units liseted on the winISD program you can click on the units and they will cahnge. THis makes it so you dont have to calculate them :)

I did download WinISD, I typed in f-mod and came up with it, on those jbl amps, I heard if you plug in all the RCA input/output that it sounds better? And what will the f-mods do when hooked up?

Type in F-mod into the search at partsexpress..It should come up. Look for the 20 hz F-mod. That should be fine. For the RE8, id suggest a 3" round port. That's what i'm using and it works fine. Download WinISD like suggested and play around with it and find out what works out best for you. My box is around .9 cu ft, but you could go smaller..actually I would suggest it. .75 cu ft would be perfect for a single RE8..again you could still go smaller..maybe .5 cu ft.

If you have any problems with it let me know.

Its fairly easy to use I think :)

I was fairly confused with it. I entered the specs on the RE8 but, I couldn't find them all. I got the ones the re shows on there site, but "Pe, Z....." one more I couldn't find but I dont remember the letter, so it wouldn't tell me the port lenght because I didn't have the Pe.

Also: Couldn't find that filter kiki, I entered it in the search, but said it wasn't in there database. Since that JBL amp doesn't have one, should I look else where??

you'll want an infrasonic filter if you're going ported, but with a JBL amp you can always just add an RCA level infrasonic filter from partsexpress.com
they're about $25.

I read this on a diff forum " four re8s in a 2.56 cubic one chamber box with a 4" port thats 7.75 inches long" its in a one chamber box his is in a 2002 s10, so perfect fit.

Damn waiting for all this to be bought/made/installed, in the end well worth the wait I suppose
