I am trying to wire my JBL Px600.2 to my new Pioneer Premier TS-W30001D4. Stats are as follows:
Amp:
180 Watts RMS x 2 channels at 4 ohms
290 Watts RMS x 2 channels at 2 ohms
714 watts at 4 ohms
Sub:
12" Dual 4 ohms Premier® Champion Series PRO Sub
Power Handling:
Peak: 3000 watts
RMS: 1000 watts
Impedance: Dual 4 ohms
I have blown a few subs so far by not asking for help, so here I am asking for help. Do I run the sub bridged mono or stereo? And which was should I wire the sub? The RMS on the sub should be able to handle the amp this time I would surely think, but I really don't want to blow another sub and just give up on this system setup.
Any assistance would be much appreciated, thanks in advance. Merry Christmas.

Also, I did look at the diagrams available:

and

but I want to double check what I am doing before I kill another sub.

Option 2 (series) = 8 ohm load
Voice coils wired in series
Recommended Amplifier: Stable at 4, 2, or 1 ohm mono |  |
With the amp and sub you have, this is your only safe possibility if you want to bridge the amp. You could also connect it in stereo with the same amount of power output from the amp. You would have been better off with a Dual 2 ohm speaker. Or a dual 8 ohm.

I don't necessarily have to bridge it, I just want the safest setup for what I have. Unfortunately I was sort of talked into this amp which really wound up being more than I needed. Is wiring it in stereo going to be safer?

The amp will produce exactly the same amount of power into an 8 ohm mono load as it will into a 4 ohm stereo load. I just looked at the specs you posted for your amp. The 714 watts must be peak output and the 290 a channel the RMS rating. The RMS rating is 580 X 1 into 4 Ohms

Thank you very much for the quick responses! Would the sub more than likely be safe from being overpowered in theory as well since it is rated at 1000 watts RMS?

In Theory all will be fine. 360 watts should not hurt the 1000 watt woofer.

Sorry to bump such an old post, but my bass is nowhere near where I feel it should be for the amount of money that I have put into this so far. I used to have a cheap Sony Xplod amp pushing two cheap 12" Kenwood subs, but it sounded WAY better. I got talked into making a single 12" fiberglass box that looks stock in my trunk by a buddy and he told me that if I got a dual voice coil sub it would sound every bit as good if not better than my previous setup. Now the box looks great and it does take up way less room than the two huge bandpass boxes did, but the sound just isn't there. So, my question. Would I be better off looking for a different sub here to make it louder or try to trade my amp for something that can push my sub better? Would love suggestions if anyone has any. If I should post somewhere else I apologize in advance. Amp: | Power Output | 180 watts RMS x 2 channels at 4 ohms
and ≤ 1% THD + N
290 watts RMS x 2 channels at 2 ohms,
14.4 V supply and ≤ 1% THD + N |
Sub:
12" Dual 4 ohms Premier® Champion Series PRO Sub
Power Handling:
Peak: 3000 watts
RMS: 1000 watts
Impedance: Dual 4 ohms

It is probably you box. Check the cubic footage with packing peanuts. Also make sure the fiberglass box is thick enough and not flexing. Also you buddy is worng, a dual voicecoil subwoofer has nuthing to do with how it will sound or how loud your subwoofer will play. They are simply mostly for wiring options.
