SQ in my truck, upgrade amp or HU?

Im considering changing my high amp to something with a lil bit higher sq in a few months. My old school memphis just had more clarity then my db A5 does at high volumes i think. I was was playing with my amp a day or 2 ago and set max volume for 30. At 28 the speakers didnt have very good clarity but got loud, this was playing a mp3 file. When i increased the gain to make max volume at 24(where i originally have used it) it got just as loud but a bit clearer, not as much back ground noise. Volume can go up to 40 or 45, with internal amp on speakers max with clarity was around 24-26

So i guess is it my amp or my cheaper alpine HU? The door speakers are Hertz HV-165s so its not them.

I was told by a local db drive wasnt SQ oriented, anyone have input on that?

So basically if its the amp whats a good SQ oriented amp that does around 100x4 thats not $400

If its the headunit is there anything new thats got better SQ for around 150? If i go used i really want to pick up an eclipse unit, just got get the ipod box. Ipod/USB interface is a must

There is no real SQ amp, get one that puts out the unclipped power you want. Get better speakers because that's what will make the difference in SQ, then maybe some EQ.
