this is the problem with creating multiple threads for the same question...i have a hifonics zeus Z440 110wx4 for my vocals. But my friends giving me a Hifonics amp that is 170wx4 so thats what i will have. Right now i have a 10" o2 speaker, 2 powerhorns, and two 5-1/4 on the amp, but im willing to take off some to add new ones if i need to. Its in a jeep wrangler, and my budget is not very much, im willing to pay money but itll take me a lil to save some up lol. So something reasonible. I have a 2200 watt o2 amp for my two 12" L7's.
