My PPI Art series amp that I use for my mids doesn't have a crossover so I use the crossovers that were supplied with the components. For my subs, I'm currently using an Infinity amp and I use the built in crossover. Back in the day I had an audiocontrol 24xs and 4.1 eq/line driver which I loved but I sold most of my old equiptment. I've been contemplating going back to using some auidocontrol products but I've always struggled to get the level of SQ I'm looking for in this car so I'm not sure it's worth the extra coin.
