Ok, so yesterday I was warming the car up for an oil change and started beating on the system a bit. I noticed one woofer not moving quite as much as the other. So today I took all the speaker wire out of the amps (2 bc3500's strapped) and each woofer is reading 4 ohms??? It's supposed to be wired to 1 ohm per woofer 2 ohm strapped. I don't know what I did wrong. I'm not sure if there is a different way to check impedence if the amps are strapped.? I notices the master amp gets slightly warm and the slave is cold. I need some advice as I'm gettign frazzled. The woofers are 2 fi btl 15's Dual 2's I put a camera inside the box to make sure no wires came loose but everything seemed ok. Also, when I checked the wires still in the amps they gave me 1.4ish ohms on one woofer and 2.6 on the other... now out of the amps they are giving me 4 ohms each...so idk Heres how they are wired: pos from one coil to a negative of the other coil. Do that for both subs. Wire the two remaining positives to the positive of the master amp. Wire the two remaining negatives to the positive of the slave amp. Connect the two ground terminals of the master amp to the two ground terminals of the slave amp.
