so in my expy i just installed my 4 memphis pr 10's with my hifonics zeus xi which gives me a total of 1200 watts towards subs/lows but the problem here is my speakers all around the car are stock and i knew it would be a problem but i didnt think it would be this bad because the car has the stock mach 460. anyways, when im really bumpin i can barely hear the music so what can i do to give me alot more on the high-end? i dont really want to add another amp because my electric system is still completely stock and i dont want to strain anymore than it already is. any help would be appreciated
