Need help choosing a good amp

[DWBass]

Ohms Law was named after Georg Ohm.

Some more info.

This is one of my amps. On the left you will see 8ohms=200w and 4ohms=300w. On the right you will see 'speaker output', wattage and rating. 4ohms being the minimum. I could use (1) cab at 8ohms and get 200w from the amp. Or I could use (2) cabs at 8ohms each (or (1) 4ohm cab) for a total load of 4ohms and get 300w from the amp. I cannot use an 8ohm cab + 4ohm cab. This would bring my load below (2.67ohms) the minimum. Nor could I use (2) 4ohm cabs (2ohms). I could go higher but the higher you go, the lesser amount of wattage results. I hope this helps.

Awesome, i'm starting to see the light at the end of the tunnel.  I appreciate all your help in explaining to me regarding ohms, now i know what to look for.

here are specs for a carving bx 1200
Technical Specs
 
• Advanced Equalization - three EQ sections
• Active Passive front panel input gain switch
• 5-band three sweep tone control section
• 9-band foot switch able graphic EQ
• Single knob silent Optical compressor with auto limiter
• Internal crossover for bi-amping
• Preamp DRIVE and MASTER volume controls
• XLR Direct out with Level, ground lift & pre-post preamp controls
• Effects loop Switch able by front panel or FS22 footswitch
• Tune output jack independent of mute switch.
• High-current Spekon connectors
• RMS 225W @ 8 ohms, 400W @ 4 ohms, 600W @ 2 ohms
• 800W 8 ohm bridge, 1200W 4 ohm bridge
• THD less than .03% at 90% output.
• Freq. Resp.: 20-20k Hz
• Dual speed fan
• Active Passive input (-10DB)
• 5.7 inches high x 21.6 inches wide x 12 inches deep
• Weight: 23 lbs.
• Made in San Diego, California

So when it says 600w @2hms that means it can handle a minimal load of 2ohms?

Yes it can.

I hope I don't confuse you with this, But here goes.

 Ohm's Law defines the relationships between (P) power, (E) voltage, (I) current, and (R) resistance. One ohm is the resistance value through which one volt will maintain a current of one ampere.

( I ) Current is what flows on a wire or conductor like water flowing down a river. Current flows from negative to positive on the surface of a conductor. Current is measured in (A) amperes or amps.

( E ) Voltage is the difference in electrical potential between two points in a circuit. It's the push or pressure behind current flow through a circuit, and is measured in (V) volts.

( R ) Resistance determines how much current will flow through a component. Resistors are used to control voltage and current levels. A very high resistance allows a small amount of current to flow. A very low resistance allows a large amount of current to flow. Resistance is measured in  ohms.

( P ) Power is the amount of current times the voltage level at a given point measured in wattage or watts.
 
Ohms represents the amount of resistance in circuit. The circuit being  your power amp and cabs. The lower the resistance the higher the power. The higher the resistance the lower the power. I hope this has helped

Okay.... some more info for those who care ... http://www.sengpielaudio.com/calculator-ohm.htm

Check out the Kustom Groove Bass 1200 HD. You won't be disappointed. I've had mine for about 6 months. LOVE IT. I think it retails for about $650.
