Hi all, I have a 12" sub I'd like to refinish the box and bring it to use for my home theatre. I'd buy a plate amp to wire it up properly. Is there anything I should be worried about? It's a 12" Sundown Audio C12 in a ported box tuned to 28hz. Thoughts?

Where's the plate amp going to sit, and what don't you like about the box now?

The box is in "rough" shape. The previous owner never finished carpeting, etc.
Plate amp would likely sit on the back of the box.

The difference between a car sub and a home sub is a home sub
is like furniture, a car sub not so much...

many of the best home sub, use cars sub, just build new boxes to company specs,and make the finish to your desire. just think of jl audio, they use the same driver as there car lines of driver. the phatom f 113 use there 13 w7 driver serie.
as for amp any pro audio amp will do the trick. I use crown macrotech 3600 amp . just choose a driver with 4 ohm or more preferably.

Sorry autocorrect messed up the number. It's a Sundown X12.

So I'm assuming it's ok to use in that case?

Perhaps the issue will be where you get a powerful enough plate amp for that sub that's rated at 1500w RMS.
You might be better looking out for a pro amp and building the sub passive.

Thought about that, but at the end of the day I don't need it to work at its fullest potential. Right now I'm only using a 500wrms amp in my car and it sounds amazing. Just looking for it to compliment my current surround sound, not overpower it. I found a plate amp on parts express rated for 1000wrms , $329. Not a bad price (USD of course...) lol

A power amp would be nice but I'm trying not to break the bank and make it a clean install. If I can help having another amp somewhere that would be great

Is there a spec sheet for it? Very few car subs work well in a home environment. Usually they have a much higher FS and higher QTS, gives them a bump in response between 40-70hz. In a home they usually have a very boomy one-note type of sound.

Scroll to the bottom of the page and select X12.

Specifications X 12"D2 X 12" D4
RE (ohms) 3.80 ohm 6.1 ohm
FS (Hz) 36.1 hz 38.3 hz
Vas (L) 17.1L 13.2L
Qes 0.44 0.50
Qms 4.89 4.92
Qts 0.41 0.45
Le (mH) 2.41 mH 3.82 mH
BL (NA) 25.2 30.0
Mms (Grams) 326.2 g 305.6 g
Cms (uM/N) 0.06 mm/N 0.06 mm/N
Sens (1w/1m) 84.4 db 84.4 d

These should be good in a box, though at only 84db/W you'll need lots of power to stir them up.

Was thinking one of these:

Was also thinking of a power amp (behringer or something) but most don't have 12v triggers.

that sub should do pretty damn fine in home, as long as its well implemented !

All my subs at home came from "car audio" subs, it all depends on the specs of the sub, although, i find that you usually cant have the same box for home and car environment... you dont have the low end "cabin gain" in your home like you do in your car. But of course try it out first and if it sounds right to you with the same box then thats what's most important!

I personally always go sealed or very low tuned for home use, usually ~18hz to 25hz max...

also, a pro audio amp will always be more versatile on the long run, especially if you wanna switch subs/enclosure every now and then, you wont be attached like you would with the plate amp.
