JBL? are they any good? the 600.1
how about harrison labs 400.1?
xtant a6001?
any other mono amps or 2 channel? i need em for 2 12 W08, ima wire them to a 4 ohms load so i need something like 300@4ohms the most amount ima spend is like 325

 

Most mono's will be Class D.
You not asking for much W's so I would go with 2-channel bridged.
High quality, very musical, and underrated, and US made;
Lunar 60x2, 240Wrms x 1 @ 4Ohm for $289 (small footprint and built-in fan, black or white)
or
Arc Audio 2050CXL, 245Wrms x 1 @ 4Ohm for $284 (available in black chrome or blue).
Both of these amps are underrated and are workhorses. I have a Lunar on my sub and it has performed flawlessly. Very simple but serious amp w/o the bells and whistles. Lunar would be my $300 pick.

 

Phoenix Gold Ti600. Make sure that you get one with a bass adjustment knob. Mine comes with one and is mounted by the cruise on/off switch.

 

Gotta agree with the Phoenix Gold

 

$325? Go with a used old school rockford punch 200ix DSM

 

TLDude:
Or get an old body design Rockford amp...for 300 @ 4 ohms...go grab yourself a 360a2 for around $200...at least my 400a4 was $200. But it'll be a long hunt to find one. I think I did answer this Q online for you though...so well let me know how it goes.

Oh and the PG is a good choice too But I'm an old school RFer
