ok guys...i found a few of these amps for sell and i can get any of them for ~$300 shipped! (the CF 1000d is $250 shipped)

i'm putting my bp1200.1 on ebay very soon, and i'm gonna prolly get on of these amps. which of these do you think would be my best bet in an SPL install for my SX15 (dvc 2ohm). (i'm gonna use it daily too, but in another box.)

i'm going for SPL here, and i wanna stay in usaci 0-300 classes. my box is gonna be double walled 3/4" mdf, 1/2" threaded rod for bracing, bout 80-100sq inches of port, and bout 5.5cu ft(all w/ 1/4-piped corners and maybe a lil concrete :-) )...i already have the MDF, i'm gonna prolly do the build this saturday. i'm gonna take my deep cycle/cranking batt out of my boat and use it just for the comps...lmao (850cca, 205 reserve capacity)

this is for some comp comming up on oct 15th and 22nd. the highest spl of the day last year at the oct 15th show was 149.xdB w/ 1 dd9515 and 2 xs100's in a CRX...winning spl in most classes was in the 143-147 range. i'm doing 145dB as of right now...help me out here guys.

Well you just answered your own question. If you want to stay in the 0-300 classes, Orion 275G4 is it.
That amp is stereo, so it'll work perfectly with 2ohms DVC.
In case you forgot, 275 is 1200w rms at 12v.

But all of those amps are legal in the 0-300w classes.

I wonder how much louder (if any) those amps would be than my bp1200.1. You see, as of right now my box rise is about 3.3ohms...all of the amps i listed put out ~400-450wrms at that load, but the bp1200.1 is rated at 600wrms @4ohm...that would be like 750-800wrms at 3.3ohm w/ box rise.

crap...i think i'm bout to talk myself out of buying a new amp :-(...someone set me rite!
