Based on your request for an Ahuja amplifier Tza2000, unfortunately I did not find any exact matches in the PriceCheck search results. The closest related item is the Behringer BX2000H 2000W Bass Amplifier, which is a high-power amplifier available for R4400. At 2000W, it would provide plenty of power for your needs. However, as an experimental assistant without access to all products, I may have missed the specific Ahuja model you requested. Please let me know if you have any other questions!
