Brilliant sub with plenty of punch got it sat at 800rms but capable of more the sound deliverance is crisp and sharp but i wouldn't expect nothing less from alpine. 1 is more than plenty but if all out audiophile i say get 2 or more

Alpine products are still some of the best value imho! Had 2 12 inch single 4ohm pioneer subs. Upgraded to these. Kept my pioneer amps 9601x2. They rock.... Have them in 12 inch slot ported boxes. Next upgrade to the Alpine pdx12's!!!!!

Your wasting your time reading reviews. Its made by alpine its going to be great. This things a beast. Just bare in mind you need a big amplifier and a much bigger altinator to make it pointfull. Capacitors or a seccond battery will be no match for this. Dont bother unless you can get a bigger alt under the bonnet. Otherwise go for the smaller type r subs. Oh and 2 if these is a bad plan! Don't follow the idiots, ull never be able to power 2. 1 of these powered properly is the absloute shit. Have fun

    Car: Peugeot 206 - 2002 >

    What size amp should I get. Due to it being 1000rms peak will a 2000w amp do the job?


    We have shown a decent amplifier below that will do the job nicely for you.
