does anyone have an escape audio set up

--------------------------------------------------------------------------------

i have a 98 corolla gli with a 1-din pioneer mp3 player, pioneer 3-3way 6.5 inch rears and jbl seps front, and a hifonics-powered pair of 1o inch boston acoustics subs.

i plan to transfer them to the ford.

problem is the HU, 2-din.

i do not wanna buy a new HU dahil mahal.

where can i get a spacer para malagay 1-din? like sa mga old toyotas na they ave a cassette/container bin na lang to fill the other din?

or where can i buy 2nd hand 2-dins na galing sa mga revo vx200? magaganda naman yun.

if i retain stock unit, may rca outs ba to for subs?

for speakers, do i have to transfer all speakers o lagay ko na lang yung seps in front and use stock rear for fill tapos subs?

finally? sann puede pagawa ito? im wary kasi di naman madalas i set up escape, baka magasgas dash at mabali mga clips pag di marunong
