i was just hosing some degreaser out of my engine bay , and i accidently hit my alarm siren . it has just started making some really weird sounds , like screatching and roaring . water must have gotten in the speaker ! i tried arming and disarming , and you couldnt hear anything , but weird sounds. now iv left it for a bit and it had gotten a bit better , im wondering could i replace the speaker in it? or is the whole thing f**kd?
