IMhizzle, I have the same sub and my amp died too. Is the amp you bought a direct drop in replacement? Holes lined up correctly, etc..? Thanks.
Crazy necro - but yes, it's legitimately the same plate amp the sub ships with.
They are exactly the same size, and the spl-150 amp fits perfectly in the R-115SW cabinet.If you follow the link posted in post#14 (see below) it says the exact R-115SW replacement is back-ordered (likely, forever) but offers a link to an SPL-150 amp which it says can work as a direct replacement. No idea about the holes lining up perfectly but it appears maybe so.
edit: I see that someone in the comments section for the SPL-150 amp claims that there is a 1" size difference between the 2 amps. No idea whether that is correct or not, though. Seems they might be assuming that based upon the posted photos, though. They appear to me (as best I can tell) to be the same size in the photos.
