I see, ok, well, grah - infinity amps arnt very good then? I can get that 600 watt mono amp for 150 bucks, so thats why I was leaning towards it.

There is actually no such thing as underpowering a sub. When you play at low volumes, you are playing at lower powers (say you have 600 rms, when the volume is 1/4 of the way up, it could be putting out 70 or 100 watts). Very rarely do you hit the max of the amp.


I have a Perfect 12.1d by the way. It played well even on 150 watts.

So your all saying that 300 rms to each sub will still make them sound very good, even though they are rated for 350 each? I was worried about not only underpowering them, but trashing my amp, and not having the subs sound up to their potential.

Edit: What would you say about a
Infinity
REF611A
600 Watt Class D Amp for those subs? I can get one fairly cheap. Are infinity amps any good?

Buy Bills amp, or look into a JBL bp600.1, KickerKX600.1, Hifonics (brutus) I dunno the models. MTX500D, or a Rockfordfosgate. All there 600rms(round there) amps can be had for $200 or less. I know some on here don't like MTX or RF, but everyone I know that has used them, hasn't gave out, and put out what they claimed, or were close to it.

ill sell you my american bass amp it does 800 watts at one ohm great amp for these woofers refrences all over this site and ill sell it to you for 250 shipped

You mean dual 4 ohm? You can wire both subs for either 4 ohms or 1 ohm at the amp.

You can look for monoblock 1 ohm amps or bridgable 2-channel amps (4 ohms).

As for 700 rms, you don't need that to get the same performance. 600 rms between the two is still more than enough power for them. They are pretty efficient.


1200 rms amp, yes to upgrading the alternator on 90% of vehicles.
