On a single good battery that is 650si or less you'll maybe get 1500w from a 20.1. At 08 finals we tested the Stetsom 4k2d @ .5ohms is .5db down from a 10k @.5ohms. If I remember correctly 10k netted about 4000w dropping voltage to 10.3-10.5v and 4k2d about 3500w dropping to 10.7v. As you can see the small battery for street A is tough to get good power from.
Besides the amps listed above your other good choices for street A are
American Bass 500.1
American Bass 1000.1
Cactus Sounds 5k
Cactus Sounds 7000.1
Cactus Sounds elite 12
DD Z1A
DD Z2LV
Now these are pretty expensive amps but are all with in .5db for a 650si battery.
If money is tight and you don't mind amps that are .5-1.5db down from amps listed above then for around $700-$800
Sundown 3000

Cactus 5k
Stetsom 4k2d
American Bass 500.1
I probably missed a couple amps but hope this helps. Street A comes down to efficiency due to limited battery size.
