[QUOTE="danielnews, post: 8779209, member: 679797"] I ordered a 5 channel amp but it was on backorder for 4 months so I ended up not getting it. My brother gave me a couple amplifiers and a 12" sub that someone gave to him. I'm wondering if I can string them together, if it'll be enough. I'm not looking for anything crazy, just 4 speakers and a 12" sub. I'm wondering if I necessarily need a large amp to run the Alpine sub, or if I could do with less in the meantime. I seem to remember hearing that if you underpowered a sub it could damage a sub so I wanted to be careful.
