new alarm? parts from old one? which one?

Hi all,

i am new to this board and have a couple questions but 1st some background

I have a 2001 jeep wrangler se model (softtop) has a sound bar and a center console....

i own (when it worked) a ungo ms8300 car alalr, has a double shock sensor, and a proximity sensor

i let soundtrack install it and that was the biggest mistake i have ever made...

the alarm was never mounted properly, and as such, has fallen out at my feet while driving, and now no longer works..

so what alarm should i get i was just gonna install it myself this time, also can i use any of my old sensors? should i get another ungo? seems like most shops arent carrying them anymore.....

since my veh is a manual i cant use remote start (i dont think) and it is a soft top so electric windows wont help lol...

actually can i do remote start? would be nice for the winter.....

sorry this is so long thanks

Aaron
