any good? and will my 380rms amp power this enough to shake the car since its rms in 600

What amp do you have? A model # would be nice.

what amp are we talking about...and how will you run this woofer, in a sealed box or ported box that YOU have built?

[onelivinlarge]

pionner gm 5400 and will be bulding a ported box and going to tune to 40hertz unless yall know of a better tuning i should do for bass

[C-Fizzy]

that amplifier isn't even stable at 2 ohms. Unless you plan on running at 8 ohms. Which you won't get much power at all.

Edit: nevermind, you can run one coil to each channel. Which will work great. I suggest tuning your box to around 35 hz.

i was planing on running at 4 ohms in bridged mode wired like this http://a248.e.akamai.net/pix.crutchfield.com/ca/learningcenter/car/subwoofer_wiring/1DVC_4-ohm_2ch.jpg

edit or you are right running one coil to each channel

You can't run a dual 4ohm woofer at 4 ohms.

thats impossible. you cannot wire a SINGLE dual 4 ohm woofer at 4 ohms. its either 2 (parallel) or 8 (series).

2 channels arent really meant for woofers. if a song you are playing has more bass on the left channel and less on the right (for example), then the voice coils will be fighting eachother and that isnt good.

[onelivinlarge]

but running one to each coil will that be enough power to effectively power the sub?

That's why you use a splitter to make both use the same signal.

Edit: Take one set of RCAs off of the HU and use some RCA splitters to send it into the amp, that way both channels will be identical.
