RE: My new sub/amp
The adhesive foam that came with my sub- where does this go? It was in the same packaging as the outside plastic ring for the sub but does it go in between the sub and the box or the outside ring and the sub? Thanks.

RE: My new sub/amp
OK, i wasnt sure what his sub was rated at, didnt exactly give the model number. Yeah you should be fine with the single sub there.

And it also means each voice coil will be able to handle the rms power rating of the sub. So you are just going in circles.
IMO, your setup is fine. You will not be underpowering the sub. The sub you bought is rated at 200watts RMS at 4ohm, 400 watts at 2ohm. Your amp is rated at 150 watts at 4ohm, and 300 watts at 2ohm. So in your specific situation you will be running the amp at 150 watts RMS at 4ohm and the sub will be able to handle 200watts RMS at 4ohm. This should be fine. It will thump plenty loud and you shouldn't have to worry about burning up your voice coil or blowing the sub.

OK i just looked up the spec's to your amp, it is basically saying if you put it going into a 4 ohm speaker you will be outputting at 150 watts RMS. If you put it into a 2 ohm speaker it will output at 300 watts RMS.
Depending on what the sub is rated at, yes it might be under powered. So with that being said let me give you a little lesson on amps and subs.
If your amp is out putting at 150Watt RMS you want your sub/speaker to be between 250 and 600 watt RMS at the most.
If your amp is out putting 300 watt RMS you want your sub to be between 400 and 800 Watt RMS at the most.
Now since your amp can run at 2 ohm load, i suggest returning that sub you purchased and buy a dual voice coil 4 ohm, or buying a second 4 ohm single voice coil sub. What this means is each voice coil/sub will be 4 ohm, and when you hook them up to the amp in parallel the amp will see it as a 2 ohm load and you will get more output of your amp.

Hey, just got my fosgate P2 single voice coil 4 ohm sub and p3001 amp in. My friend scared me when he said that amp might be under-powered for my sub. Anything to worry about?
Also, after looking at the amps directions, i'm confused. I know there's always a way to wire up this stuff but on the amp, there are two + & - terminals for speakers. Even thought this is a mono amp it looks as though it's two channel. Anyways, I only have one sub so how would I wire this sub to 4 ohm...it looks like if I only utilize one of the speaker outputs it has to be at 2 ohm. what gives? Thanks.
