I'm having the worst time trying to find a replacement cab(s) for my Ampeg SVT410 HLF. First off, the only thing I really like about my currect cab is the wattage rating. I hate the size and the booming low end. So I've deciced to buy some or one Avatar cab. I want the 2x10, but I'm scared I'll have too little low end. So, I'm not sure if I want the 2x10 plus a 15, or if I just want the 2x12 combo. the only reason I'm skeptical about the 2x12 is, I'm not sure it'll fit in the back of my car. Can anyone help me?
