alarm questions
im sure most of you who have an aftermarket alarm must have at least one backup siren. so you guys may answer the following questions for me:
1. does adding more backup sirens mean less volum? e.g the 1st one you add gives out 12v when the 2nd and the third one are added, it's not gonna be as loud as one?
2. is it better off to install a backup siren inside or outside the car?
3. did you extend the key hole for the backup siren to an accessable but secured spot or it is still on the siren? i've asked two installers and they gave me two different answers, so im wondering.
4. should i put the brain in a hidden spot underneath the dash or there's a better place to hide it? im thinking about put it hehind the dash but not in the hood, possible?
it's great if you can answer me these questions.
