Re: Correct Amount of Power needed for my subwoofer
1000 watt or bigger you always wanna have a little play room with the amp so it wont blow or short out. also if you do decide to add another sub....the amp will still be able to push both subs.. yeah so at least 1000 would be perfect but if you dont have the money about a 500watt would still push it hard. just make sure you have all of the options on the amp tuned to make it sound the best and make sure you have the right enclosure for your car. 500 would do...but 1000 would be best =)

For optimal performance there is really only one size for the box .Firstly, you get two different types of subwoofers, an open air, or closed air sub. If it is an open air sub ( hole with mesh in the center of the magnet) no ports are required, and the box should be sealed on the inside with silicone sealant. If it is a closed air sub ( no hole in the magnet) you need a 50mm port about 120mm long. If it is a 12 inch speaker, the box size will be 13 inches x 13 inches x 13 inches.
yeah, you likely cant build a box to tune 35hz... try just building a box that has correct spec by the manufacture for ideal operation, and adjust the gain accordingly, that's where you will attain your desired hertz, oh and by the way hertz refers to signal, and pulse rate,

you are going to need an amp that can supply the right amount of rms power to make it sound good. these sony subs are rated for 380 watts rms. so in order to find an amp that will supply two, you must multiply that figure by two. so you will need an amp that can supply around 500 to 750 watts continuously (or rms). also you are going to want an amp that is either class d or class ab rated. these amps are built to push subwoofers exclusively and will give you the best efficiency and sound out of your subs. you will also want to get an amplifier is a monoblock amp, and not a stereo amplifier. make sure the amp can put out that rms rating at 2 ohms as two 4 ohm speakers equal 2 ohms wired in parallel. i have a kenwood kac9152d that puts out about 2000 watts max at 2 or 1 ohms (900 watts rms) that i used with my two sony xplod 10's for about 2 years. it was kick ***! now i dont know if you need that much power but they will handle it as long as you dont push them too hard for long periods of time, otherwise you might end up blowing them up! (depending on the box size that is, and the quality of it as well...)
i have years of car audio installation experience and can help with setting up and wiring any mobile entertainment system you can imagine. may i ask what kind of music you listen to and what kind of box do you have for these subwoofers?
It comes down to Amperage and RMS, your best bet is to go in and talk to a salesman at a stereo shop. That way he can decide on what sort of power you want and how you wanna use the subs. But 1000amp AMP is probably a good start 4 channel of course. Alpine or SOny make some kick a$$ AMPS
