[QUOTE="Jeffdachef, post: 8583688, member: 650438"] throw your stock speakers back on and put them on the amp. They'll surprise you. Every radio has a DAC or else it wont be able to play anything. The stock stereo also has its own built in EQ curve which boost things up to try to make up for the low quality stock speakers they used. So in a sense the stock stereo will only work well with stock speakers. When you use aftermarkets, they are subjected to the same EQ cuve which boosts frequencies that should not be boosted which leads you to your issue of harsh highs. Yes a DSP will make every difference possible. You wont get anywhere without EQ tuning even in a good setup with a good head unit and great speakers, you'll still need massive amounts of EQ tuning due to the listening environment. Those polk MM marine speakers shouldn't sound harsh at all, my old manager's boat used them and he barely needed to lower the 6.3khz range a bit on his kenwood head unit. Soo how crappy the sound would look like without EQ? with EQ should be more straight and linear which leads to very pleasant, full, smooth and detailed sounding music.
