Ok guys i think this will help all of us noob's How can you tell if the subs you have are going to fry your amp. Ex. I have a Kenwood KAC-9102d amplifier will two 12 inch alpine type r's kill this amp the subs say 1000 rms (combined and a max 3000 rms combined. what do you think the say four ohms to what ever that means
go to rockfordfosgate.com the go to the support menu and click woofer wiring wizard. Generally 2 dual voice coil subs can be wired at 1 or 4 ohms, but cheap amps will fry at 1 ohm.
