well, I have the AIWA x227 and the MA-01 and I love them both. I have had the x227 for about a year, and the MA-01 for about a month. I bought them because they have the front audio input, which I use to plug in my laptop and watch movies on trips. The x127 is basically just the x227 without the removable face. I screwed the face on anyways, so not a big deal to me. I love music, but I am not one to spend a lot on car audio. I listen to mostly punk and ska. You don't need a big amp and subwoofer for that. Both units put plenty of volume through my infinity speakers without an amp of any kind. I have owned pioneer and kenwood and alpine, but I spent way too much on them. I am much happier with what I have now. Everything I want at half the price. I am very impressed with the quality of AIWA products. I also love crutchfield! Talk about awesome customer service! This is a hot deal. Jump on it.
