okay so im looking to get a decent alarm system with remote start. I already have a remote start system in it but there isnt an alarm with bothers me since my cousin walked up to my car and opened my door with his 2002 s10 key. I dont want to risk my sub/lights getting stolen when i move to the city! heres what ive found so far Omega AL-1820-EDP (al1820edp) - Car Alarms with 2-way Paging - Sonic Electronix
would i run into any problem instaling this since it already has a r/s installed? opinions please!
