Parameters for the SWR-1242D ?
 

Does anyone have the parameters? I cant find then, now I can't calculate a box. And would a AUTOSTUDIO : E-180.2 be enough for this sub? The parameters for this amp are as follows:

Power@4Oom(RMS): 2x180W
Power@4Oom(RMS): 1x560W
Power@2Oom(RMS): 2x280W

Frequency: 10Hz - 50kHz
Inner sensitivity: 200mV - 6V
Hi-pass filter: 75Hz - 2kHz@18dB/Oct.
Lo-pass filter: 35Hz - 300Hz
Size: 250x57x360mm

if the amp is not bridgeable, then i don't see how you can properly power that sub. At the same time, even if it was..... 520watts is how much that R is getting assuming no voltage drops/box ris/ amp does rated, etc.

your gonna see less than that anyway......

go to alpines website under subwoofers, there is a downloadable pdf file
for the params.

Thx for the link Ruger.

Very true but that amp is bridgeable and yes thats not enough power for that sub.
