dont u need relays or something...where do i get them?

if it helps, im runnin a 250 amp mechman alt...kinetik 2400 and kinetik 3800.

You'll want to run a relay that sends power to the sirens switched by the siren output on the alarm.

Search for a member named ''blados'',I believe. He had a similar high number of piezos. Might give you some ideas.

no amp needed,they hook up to the alarm brain

aight cool. im thinkin bout 20 now cuz I just got offered 20 for $50.

Question...how hard is it to install these to an existing alarm? im gettin my alarm installed friday...but if these dont come in tha mail until saturday would it be hard to go back and hook them up? like would you have to do tha whole alarm install over? or should I just wait for them to get here to get my alarm installed.

Id wait, and have them do it all at once. if you're going to run 20 (a little overkill IMO, 5-10 would be plenty loud inside and outside the car) you're going to need to run at least a couple relay's. Find out how much current each piezo draws, and add relay's as needed.

Basically you use the siren output to trigger the relay(s) with the siren, thus whenever the siren is blaring, so are your piezos.
