Just got some pionner speakers 180w max. They sound good and better than oem. Now what hu should i get. I am planning on staying with these speakers since im not wanting to bump it just have a nice set up.

 

I am happy with the sony dsx-s300btx, but you cannot go wrong with any of the major brands (Alpine, Kenwood, JVC, Sony, Pioneer, etc.) I only replaced my HU. I am still running the factory speakers, and I did not get an amp. The sound is much improved over the factory HU.
