[QUOTE="EDL, post: 7387772, member: 634038"] I don't have an amp yet. I have a Dodge Ram quadcab pickup. I want to run the Infinity's in the front and a single sub under the rear passenger seat. Space is very limited, so running a mono block for the sub and another amp for the speakers probably isn't going to fit. I can't put an amp under the front seats (power seats), no room. The idea is a sealed box under the rear passenger seat for the sub and an amp under the driver side rear seat. I was thinking a 4-channel amp, run the Infinity's off two channels and bridge the rear two for the sub. Rear speakers in the doors to run off the HU, just for fill. So, if I understand correctly, bridging the rear 2 channels will run them at 4 ohm, but the front 2 can still run at 2 ohm? Also, in this config, I need either a 4 ohm single voice coil, or a 2 ohm dual voice coil sub so it presents a 4 ohm load when wired up? [/QUOTE]
