Images didn't want to show up so we'll try again...No that amp is not going to be enough. I'd highly suggest you go right up to at least an amp rated at 500-watts rms into 4Ω and buy an 8Ω cab for it. It will deliver about 250-watts into one 8Ω cab and I'd suggest (and use) an 8 ohm 210 cab for that. Cab should handle 300-watts rms or more so 250-watts should be fine with it. My 8Ω [Invalid or Expired Link Removed] handles 700-watts and I feed it 400-watts from my DNA-800. Then when you need to play a bigger place you can buy a second 8Ω - 210 cab. Two 8Ω cabs will put a 4Ω load on the amp and unleash the other 250-watts rms that the 500-watt amp can put out. That gives you a de facto 500-watt 410 set-up, which should be plenty for any place you play without FOH reinforcement. Down the road you may eventually want to go up to an 800-watt amp.
Take a look at the Eden TN-501 class D amp. It puts out 500-watts into 4Ω and weighs 5.3-lbs. You may also want to take a look at the [Invalid or Expired Link Removed] amp. I use one of those. It puts out 800-watts rms into either 4Ω or 2Ω and has a built in compressor with adjustable threshold and ratio controls. It weighs 4.8-lbs. Street price on the DNA-800 amp is $799. I think the TN501 is about $150 less than the DNA-800 amp. You may be able to find them used for less. Street price on DNS-210 is ~$849 and used is usually around $600 though I saw one for $499 once.
Be aware with most amps if you buy one 4Ω cab, you won't be able to add a second cab later because that would drop the ohms load to 2Ω. Most amps have a 4Ω minimum ohms load. If you get an amp that can handle a 2Ω load, then you can get two of the 4Ω cabs. But if it doesn't handle a 2 Ω load, you can't and you really should get an 8Ω cab so you have room to add another cab later.
