Hitron HPA400.4

I'm powering (2) 6x9's and (2) 5 1/4 inch speakers with this amp. It does the job pretty darn good. This thing runs hotter than a firecracker tho so I think I'm going to put a couple computer fans on a relay to keep it cool. I was kind of disappointed seeing it only has a 15 amp fuse in it. However if it lasts 6-8 months i can't complain for the price.

I really liked this amp and always have liked the brand hitron in amplifiers. I would recommend it, it does no overheat at all.

Cheap little amp does the job well for what i needed it for.

Already had 4 speakers with sub in expedition... wanted to add extra speakers to 3rd row and tweeter on dash... works great and kids love the improved sound for watching DVDs... I've had it now for several months... no issues

Definitely an improvement in sound quality over my cheap head units "50x4" internal amp, makes the highs sound better, and more power in the bass as well. Louder and overall a cleaner sound then before, except deep bass is more distorted than my internal head unit, but most likely because of the more power being delivered than my stock door speakers can handle, a built in variable high-pass crossover would solve that problem, but then again this is best used for aftermarket speakers anyways For improving the sound of stock speakers this is not a bad choice, it's power output is perfect for the stock speakers.
