Your questions are answered in the quote.
I'd be interested in a little more information.
Is the stock sub a dual or single voice coil? DUAL 2ohm look at the diagram for the premium, there are two sets of wires for 1 subwoofer.
Is the W3 you're running a dual voice coil? DUAL 4ohm
Where are you getting the signal for the amp? The infinity amp wires leading to the sub.
I take it you had to run a new line for the amps remote turn on? My amp has a kick start that reads the signal and turns on. No remote needed
Isn't the stock amp powering the sub at 2 ohms? YES
On another thread a guy using the same sub as you said it didn't fit without using cork board to space it out. Any info on this. IT fit without spacing it. To make sure it didnt whistle or leak I used heavy/wide/thick foam seal tape.
Thanks
Sorry for all the questions

I did this before I started hacking up the factory wiring and the JL sounded good if not better then the stock subwoofer with JUST the infinity amp behind it. I would recommend replacing the sub with a JL Audio W0 series sub if you are not going to add more power!

When just replacing the sub, did you get anymore boom. Or did you just get a nicer, cleaner, crisper, bass.

E1200 JLAudio monoblock 200 watts RMS @ 2ohms (subwoofer wired to 2ohms)
It had better sound quality at lower levels. I didnt have to turn the stereo up to get it to play loud. All the things you said but without having to crank it.

Thats cool, I recommended that you fill the enclosure with the sub your choice. Just as long as its smaller then 4 inches of back mounting depth.

Do you have any more pics of how you tapped into the harness for the sub?
So you used speaker level inputs into your amp?
In the other "Infinity Subwoofer Replacement" post you said that a line level converter should be used when tapping into the factory sub wires so you do not harm the factory Infinity amp. Did you use one? If you did, I can't see it in your pics.
Thanks, and good job btw.

Answers in "wheat" color.

I did not use an inverter but I have my gain turned all the way down. My amp will accept upto an 8 volt input. The infinity amp is 2 volts amplified. It is still too much IMHO but for now its run directly to the amp. I like this because the infinity amp has smart technology to control the output of the amps low pass filiters (see my post on the infinity amp) I just have my amp set on full range and the stock system controls the subwoofer. The gain on my JL Audio amp is all the way down and its still too much!
