Unfortunately I dont have the greatest subs/speaker combo goin in as of now. I still have to budget my self. I have a pair of 10"type x that i have from my last setup only i never shoved this much power into them. For my next choice though i dont know if they will be 10s or go back to 12's space is a big issue and weight, well thats kinda gone. Im stuck between 2 batteries and between choosing alternators. This setup isnt gonna be going in for a while. At least I know the amps will last and can be moved to my next car.
