We just changed the speakers only, and that made a worthwhile improvement, even with keeping the standard head unit. It was about 5 years ago I changed them, but I think it was pioneers I found to be the closest match for size.

I seemed to lose BHP when I removed the intake resonator! I've got a performance meter which I use now and again. Here's the results I've recorded so far with my 06 WRX. Power is at wheels Standard 180 bhp K&N Filter 180 bhp K&N with intake resonator removed 173 bhp (I conduct the test on the same stretch of flat road, and perform 8 runs. Then calculate the average reading) I was gutted, as the noise it make is lovely. But I've fitted it back on again last night due to the above result. When I get time, I've going to get a spare resonator and cut off the silencer part, as I've read someone else do. This should keep the cool ducting into the airbox. If I do this, I'll post the results here also.
