I need advice on running a single Perfect 12.1d It has dual 4 ohm voice coils, and is rated at 350W rms 1400 peak.
I originally planning on using infinity amps, but I have heard bad things about them. How would kicker amps work with infinity subs? Does anybody else have any other ideas? looking to spend around 400-500.
definately cheap compared to your price range, but it puts out the perfect power for that exact sub

what type of box? if sealed that sub is rated for 500w rms
the mtx 421d would get the job done cheap and nicely. not sure which is better between the alpine or mtx? The alpine seems to have some good features but I know the mtx will last. I haven't heard good things about the digital amps lifespan.
It's gonna be in a sealed box, probably around 1^3 exactly. I have heard that perfects can handle much more power than they're rated at, does anybody know about how much they can take in a sealed box?
I don't know where it says it's 500rms for a sealed enclosure...If i'm not mistaken, the rms would increse with a ported box, not a sealed box. Simply because a sealed box allows for more control.
I'm not sure how much they can handle, I'm going to be running mine a little under, about 300.
a sub can handle slightly more power in a sealed enclosure than it can in a ported enclosure.
greater efficiency is achieved at the frequency at which a ported box is tuned, resulting in more output at that frequency. however, it is harder to control the sub below the tuned frequency of the box, which can result in over-excursion, or "blowing" the sub.
in a sealed box there is no way to release the pressure within the box, making it harder to push the cone of the sub out. conversely, in a ported box pressure can release through the port, allowing the cone to move easier, or to move the same distance with less power.
I have a coworker running the infinity 610a on a single perfect 12.1d in a sealed box at 1.2^3. that amp is rated at 657 watts rms! "watts" up with that?
