Hey guys, glad to be back on here. I just bought some new equipment:
2 - JL Audio 12w3d2 (300wRMS each)
1 - Kenwood KAC-9102d
Kenwood specs:
ftp://inform.kenwoodusa.com/Manuals/kac9152d.pdf
The JL's as most of you know are dual 2ohm coil speakers. I plan on wiring each speaker's coils in series resulting in a 4ohm load for each. Then I will wire the 2 speakers in parallel for a total load of 2ohms.
The Kenwood amp is stable at 2ohms. However, I don't know how to wire the amp. Specifically, since I'm running in parallel do I take the two positives and place them on one of the + inputs on the amp and the negatives on one - input? If so, which set of terminals? I was under the impression that, some mono amps are internally wired to run the inputs in parallel, which makes me think that I would wire each speaker into their own set of terminals, then the amp runs them in parallel for me...but I'm confused. THe manual isn't very detailed.
Could someone with intricate knowledge of this amp, or mono amps in general point me in the right direction? Thanks in advance guys, I know y'all will come through...you always do!!

These subs match that amp well. As you have stated, wire each sub for 4 ohms. (both coils wired in series, observe polarity)
Then wire each sub (4 ohms) to the amp. This amp has 2 sets of output lugs for ease of wiring multiple subs. They will be in parallel via the amp output automatically giving you a 2 ohm net load.
If you have a ported or vented enclosure, use the Infrasonic filter setting of 25 Hz. Avoid using excess bass boost features on the amp. (not more than +3 dB)
We have a diagram link that shows how to wire your subs and amp in a series/parallel configuration to 1 set of output lugs on an amp. This method will work fine too.
