got pionner deh-p6800mp..should I buy a new one?
 

I got a pionner deh-p6800mp HU and I'm gonna buy :

-front speakers : Alpine type R component (6.5 inch)
-rear speakers: alpine type R coaxiale 6,5
-Amp : dont know yet

- sub : probably a JL audio 10w6v2
-amp : dont know yet

I was wondering if my HU will be ok ( 2.2v...high impedance) or should I try to sell it and buy a new one..at least the premier...
