I was hoping someone could please help me out.

Currently I have a JBL 300.1 mono amp that is 150 x 1 @ 4 ohm,
and 300 x 1 @ 2ohm (RMS).

I am thinking about buying a 12" Punch p2 sub (200rms, 400max), 4 ohm sub.

Question is:
1. Would you even recommend this?
2. Can I run this sub @ 2 ohms? Or would it sound any different if I ran it at
4 ohm?
3. How do I hook up my amp to run the sub @ 2 ohm or 4 ohm?
4. Is this amp too much power for this sub @ 2ohm?

As you can tell I don't know jack about subs/amps. I used to have a 12" JL W3 in my box, but it broke from just being too old. Any insight would be much appreciated.

Thanks.

1. Sounds like a fine setup
2. If its a single coil 4 ohm sub then its 4 ohms. No way around it. General generic rule when you cut the impedence (ohms) in half you double the amp work or power (watts). If it was a dual voice coil sub with 2-4 ohm coils then you could run them in a 2 ohm configuration.

With the setup you are proposing - you will have a 150 watt setup. Not really any other options. Now if you have 2-4ohms subs you could wire them for a 2 ohm load thus maximizing your amp.

But you should be fine with a singe 4 ohm sub and that amp. It all depends what you want out of your system.

Hope this helps
