Overpowering subs?

[slapperz 10+ year member]

So I saw this good deal on 2 Rockford Fosagate 12" P1's 55 ea new. and i was thinking of throwing them in a sealed box wired to 2 ohms.

Only thing is my amp is a kicker 600.1 so it puts out twice their rms rating which is 150x2 so 300 rms total. Is it worth it to buy them and give them that much power or will they blow anytime?

Also would one Kicker 12" L7 in a ported box tuned to 36hz with the same 600.1 amp be louder than the P1's? Loud is what im going for

Go with the L7...you want loud, thats what solo's give ya, I ran 10" infinity's(sealed) and kenwood 12's(bandpass) for years, I was all about SQ...Never really dabled in SPL, and if you're lookin for spl, take my advice, solo barics built to right specs are the best IMO.

Im a kicker fan tho.

I ran 1000wrms daily into a single 12" RSDc, rated at 600rms. Sub is still going strong, never a problem. It's bottomed out on several occasions, but apparently no damage...

YMMV

Amplifier output can be limited by setting the gains artificially low.

Don't do it. It's hard to tell what might happen to the space/time continuum. You could create a black hole that swallows the earth...

Dont do what? and i always thought the gain didnt determine total power? Like if it was half way it meant 300mrs or 1/4 it meant 150 it was only to match the voltage?

You can lower the gain to reduce the amount of power you amp will output. All you want to do is set it to produce the amount of power you require...

Gains are not 'volume knobs' is what you've always heard. But yes, they can be set artificially low to limit output from the amp. Imagine it like this, you are decreasing the amp's input sensitivity, so when your h/u's volume knob is at max, the amp is still capable of more output, because you've set the gain artificially low.
You never want to set the gains artificially high to try and get more power out of an amp than it is rated/designed for, as this leads to clipping. But you can certainly turn them low to limit output.

put all 600 on them you probably wont pull all the power you can from the amp and in a sealed box shouldnt hurt over powering them a bit

Put all the power to them they will take before bottoming out or getting stinky. Who cares exactly how many watts this works out to be.
