I found 3 decent amplifiers that I would recommend before Id buy that Onyx for the under $200 range that are some amps that will last you, and give you the head room for upgrading.These 2 are refurbished but come with a 3YR warranty, rather than a traditional 1yr warranty-#1-Soundstream Rubicon 1.1600D for $169.90 shipped, SoundStream Lilwonder LW1.1700D for $194.90 shipped.Brand new 1yr warranty DB Okur A4 1800D Mono AB $154.15 shipped.Id take the LIL Wonder then the Rubi,and that Okur would be my last Choice, but the S Stream amps are built much better than that MB,and should be a better made amp In My Opinion..Built Like Tanks.Just a couple more suggestions for you.//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
