November 30th 08, 12:51 AM
I am new with car audio and just want to double check.
I have a pioneer 12" TS-W307D4
http://www.pioneerelectronics.ca/POCEN/Products/Car+Audio+Video/Subwoofers/Champion+Series/TS-W307D4
and the guy at the store suggested this amp
pioneer GM-D7400M
http://www.pioneerelectronics.ca/POCEN/Products/Car+Audio+Video/Amplifiers/GM+Series/GM-D7400M?tab=B
when I look at the numbers it seems this amp would under power the sub or am
I getting all the numbers wrong.
as well, the sub is a 4 ohm dual cone but the box says 2 ohm or 8 ohm
impedance, what should I wire it as 2,4, or 8 ohm?
thought I had everything going alright, but to many conflicting numbers (in
my eyes)
any help is greatly appreciated

The sub you have is rated to take 1200 watts maximum power for a
fraction of a second, yet should take 400 watts RMS without issues.
The amp you have in mind should generate 400 watts RMS at a 2 ohm load.
Seems like a perfect match to me.
