I installed my build today and im not sure what i have going on. 4 subs wired to two monoblocks. When i turned on the key for the first time the subs made a thump and a few seconds later i could hear the subs sizzling and i shut the. Key off.. Subs thumped again and i could smell burnt coils and see smoke coming out of the port.. I had the gains all the way down and had not connected the rcas yet... So I pulled the subs and unwired them. Everything appeared wired correctly inside and outside the box.. I had my son turn on the key while i watched the voltage coming out of both amps and i couldn't detect any voltage upon turning the key on and off?? I dont know what the hell happened.. Subs still test 1.7 ohms each. Any ideas?
