HU restarts - help please

[venture]

first of all, hi everyone, first post here.

i recently put a hifonics bx1205d and two alpine type s subs in my 2002 subaru impreza. before then it had an OEM sub. using an alpine 9856 hu.

the other day i had it turned up to decent listening level, and the hu restarted itself. when it turned back on, and i turned it back up (to around 20) it happened again. and then again one more time. this has happened before, but only once at any given time, never three in a row. it doesnt happen very often either.

i dont have any problems with headlight dimming or other power issues. i am unsure of what could be causing it. any ideas or fixes would be appreciated.

p.s. sorry for poor structure, posting from pda.

My vote is either power or ground wire of the HU vibrating loose.
