im going to be installing a sytem into my ute this is what ill be running
Diamond Audio -hex series s600s splits rated at 120wrms
Phoenix Gold -Xenon series x10d2 sub rated at 450wrms
i only want to use 1 amp to run it all and ive found these 2 please give me your opinions on the 2 ive listed and your recommendations,
1. Soundstream - van gogh series VGA500.4
2. MTX - thunder 1004

there both rated at 125wrms x4 or 500wrms x2 at 4 ohm which matches the power ratings for the speakers ill be using.

which would be better for SQ?

im assuming the soundstream cause of the triple darlignton output which is high end.

ill be using a alpine or eclipse head unit.
