I would recommend that you just start reading through posts and absorbing information ... there are so many variables it will make your head spin, but eventually you will start to see how everything comes together.
It could be very powerful but it depends on box design like sealed vs ported, tuning like time alignment and phase cohesion and if ported the fb, cabin gain at what frequency, and the list goes on. Get it all right and 500 watts with a decent 12 can be more than enough.
500 watts is plenty for a first time subwoofer owner especially if you are just simply adding to an existing stock system. Put it in a sealed box and if it's not loud enough go with a ported enclosure.
Just want to add, that it takes an amp rated substantially higher than 500 wts RMS to actually deliver 500 wts. (look up impedance drop) I wouldn't hesitate to run an 800-1000wt amp to that sub, just to ensure it gets actual rated power.
Ok, I am building a box for a R2D2-10 Fosgate Sub.
Fosgate recommends a box with a (Gross) Vb of 0.59 cu ft.
The say this will give a Qtc of 0.75.
When I enter the woofers Qts (0.47), Vas (1.377), Fs (34.6) and a Vb of 0.59 into a Qtc calculator,
I get a Qtc of 0.85, not 0.75.
Good news! I got a quote from them this morning. As expected, however, it’s not cheap. Regardless, I’m moving forward and will be sending payment shortly. But I would really appreciate any donations from the community that I can get to help me offset those costs and, namely...
Okay, so lets say you have a 4 ch amp that puts out 75 wts x 4 RMS @ 4 ohms. The same amp puts out 150 wt x 4 RMS @ 2 ohms.
So now lets say, you are powering four 4 ohm mid bass speakers with only two of the amps channels. In other words, your making a 2 ohm load, on each of "two" of the amps...
I got this thing for nearly nothing... looks pretty cool. This thing sold for over $800 in 1991.

First let me say I am not the installer here (right - asking for a friend!). I took my car to a professional installation shop here in town. Quite a few excellent ratings on Google and a Linkedin profile that reflects 20+ years in the business.
I have an Audison AV 5.1K HD amplifier and a...
