    Question about my amp

    I am running 2 12W0 JL Audio 12"s.

    I have them hooked up to an Alpine MRD-M300 which is a 300 watt amp. I bought the amp for $250 which isn't too bad since the lowest I saw it for was $200 when looking online.

    I feel like the subs could probably handle more power and I am wanting to upgrade my amp. Anyone reccomend if I should upgrade since I think the subs could take more than 150 watts each?

    Your amp is 300W at 2ohm
    Your subs are 125W at 4 or 8ohm, chances are at least 8ohm with 2 wired in series (though I could never really remember the rules of resistance...stupid electronics)

    So yes, you can definitely upgrade your amp. The Alpine MRD-M500 will give you 250x1 at 4ohm with a 14.4V input; meaning that in essence 125W per driver and then maxing your speakers; if the wiring ends up meaning they really are putting 4ohm on the Amp

    Again, I don't nkow much about the whole resistance thing, but I know your drivers are 4ohms each, and so going with that MRD-M500 would put out considerably more power and not blow your speakers; but if you want to max them out wait for someone a bit more knowledgable to tell you if the resistance is actually 8 or even 16ohm because you're running 2 drivers.

    Your amp is rated at 300 W into 2 ohms. If you have two 4 ohm 12W0s wired in parallel (2 ohms total impedance), you're already a bit past the limit. I did blow a 4 ohm 12W0 about a year ago with a amp rated at 150 W into 4 ohms. The speaker's power handling is also going to be determined by the size of the enclosure they are in. The bigger the enclosure, the less power they will be able to handle.
