Ok I don't usually like to ask these type of versus questions but I've narrowed my replacement amp (for my blown RE35.1D) to these last 3(I needed a 1500 watt amp that is <18" in length and these were the only few i could find):

-RF BD1500-1, the new model

-Sundown SAZ-1500D

-USAmps md2d

The Sundown is the largest and the hardest to put on my amp rack but it's also the cheapest and from all the opinions I've seen a very nice choice.

The USAmps is tempting though the most expensive choice.

The RF is just tiny nd woud make installs easier. However, I can only afford it if I purchase it on ebay which means it will have a crappy warranty.

Any opinion, positive or negative is welcome. IF you can think of any amps that size then please add.

Seems the clear solution would be to get the sundown and MAKE it fit.

Full warranty + kick ass amp + cheap = good times

I like Johns idea, but my vote does not count.

I'd go with the US Amps, but I'm a little biased.

I'd go with what makes you happy.
