I'm finally getting some cash to replace my Crate BX100. I'm looking in the 400 watt territory, and I'm more or less decided I want some form of 410 cab in there. I've been talking over an Ampeg 4x10 for sale thats in the TB FS forums. Seems like a good deal, but then I came across http://www.musiciansfriend.com/srs7...7254290/g=bass/search/detail/base_pid/482027/ this. It may be a tad bit overkill, but I'm a youngin' so I can handle the heavy lifting. I'm just wondering the advantages and disadvantages of buying cabs and head from different places, it just seems like it'd be easier to go for something like the above link. Also, I need a reminder. A cab is lets say 8ohms. That means it can't handle 4 or 2 ohms, correct? And the more ohms, the more resistance, so the less overall power the head can use? Thanks!
