SIA2500D
This amp is small but packs a punch . I love the built in fan. It’s also nice how the logo is on both sides so reads good no matter which way you turn it lol. Sonic Electronics has been top notch on shipping and follow up messages to keep you informed throughout the shipping process. I just ordered a couple more things last night .

Gives me what I wanted!
Very good amp! Was able to push my sub to how I wanted, very clean design and great power. If you are looking for a budget friendly sundown amp the SIA series is the best choice!
