    • Budget Amo that doesn’t give Budget Power
Review Image by Wendy and Bryan Escalante
This is 100% a budget amp but it pushes my 12” REAudio SXX sub to its limits. This is a great amp that doesn’t break the bank but when it comes to the controls and crossovers you have to realize that this is not a high end amp and you’re going to get what you pay for, you want an amazing amp then you go salt line if you’re looking for power on a budget from a reliable amp then you can go with this SIA. It fits my needs perfectly and I have no complaints ... show more
