Just purchased the aquatic av head unit. Want to upgrade speakers while I'm in there. Don't have the funds for an amp after these two purchases. What would be good speakers for this unit? please take into consideration that I'll be adding an amp in the hopefully not too distant future.

Thanks for any help!

 

Don't they have a built in amp? Specs say 4x45 watts and 2 ohm stable. The Infinity 62.11's are very popular and at 2 ohms will be louder than 4 ohm speakers.
