What a mixed bag of reviews for an item from a reputable company. I guess you never know how someone wires up an amp or how they run it. I use to buy soundstream back in the early 2000's and never had a single issue with them. Bought this to replace my old HOGTUNES amp on my 09 Harley Davidson Ultra Classic. 4 6ohm speakers (hogtunes) wired in parallel to the front channels (3ohms). Used the High Level Inputs and removed the additional ground wire from the inputs because it was giving electrical feedback. All in all great little amp. Much higher and crisper sound...will definitely need to swap out the speakers soon as I'm sure they'll be put to work from the amp. At this price, and this size, it's really hard to beat.
