I'll used window caulk on the seams inside the box

Immensely. Helps me with my planning stage. Which is half the battle.

Most of the newer Crunch amps put out rated power or above I was surprised to see.

You need to be prepared to keep your voltage in the 12's. Two red tops isn't going to do that for you. You'll need to upgrade your alternator to something in the neighborhood of 200 amps and get a more stout battery under the hood (or in the trunk).

How did you do 3-way active + sub with the H701?

I bet Cammie was happy to get rid of all the scrap

The BTL isn't a sub that's supposed to sound good or get low. It's supposed to kill the meter. You should probably step down to the BL depending what power you have.

You may get some port noise, but with a flared port it'll be minimal at best. You really can't go with anything larger because it would have to be longer.. and you only have 14" to work with.

Damnit Neil, I didn't need MOAR to read.

It's a birth sheet.. of course it does what it says it does.

At 28hz using 2 2" ports they need to be 7.59". Use a flared port if possible.

If you're worried about output, port the Q. It'll still sound better than the BL ported. Tune it to something around 29hz-32hz and call it a day.

Stable voltage.

Go for it. No one here will hold you back.

4 BL 12's for me

What's your total internal capacity? And what would you like the box tuned too?

If your amp is indeed .5 ohm stable, than the sub woofer will be just fine. You wire both of the positive wires to the positive on the amp and the same for the negatives to the negative on the amp.

An isolator only really gives you the benefit of playing the stereo with the car off and still being able to start the car after you're done.

All four coils or both subs?

Yup

Did some more digging. Looks like impedance changes when you fade left to right. Presenting an ever fluctuating ohm load. One speaker acts as a ground and the other as a positive L and R. http://www.audioasylum.com/scripts/t.pl?f=...ge&m=122267 http://www.geocities.com/quadaudio/page13VariousVariety.html http://en.wikipedia.org/wiki/Quadraphonic#Hafler_circuit Crazy stuff, I need to read MOAR!

Lethal Injection Death Row Death Penalty What's the FL again? And is the Warden coming soon?

It's more complicated than that. It's almost like strapping two amps together.. but then again not. You're forcing the amp to send power to itself, except with a huge resistor in the way. Essentially putting most of the sound out of phase.

Nicely done! you'll like it

Two of the D2904/6000-01 28mm dome tweeter, neo magnet And two of the W18NX-001 (E0042) Nextel cone 7" woofer At least they're pretty
