i am using 2 channel amp, each channel can accept max load to 2 Ohm. If bridge accept tomax load to 4 Ohm. I am going to buy 2 dual voice coil woofer with 4+4 Ohm. Which connection is better? Connect each woofer voice coil in parallel to get 2 Ohm for each channel OR Connect each woofer voice coil in series to get 8 Ohm and then connect both woofer in parallel to get 4 Ohm for bridge connection.
Thanks.
Bridged to mono would be better for subs as long as the amplifier puts out as much or more RMS watage bridged as it does in stereo. A total load of 4 ohms is easier for a 2 channel amp to deal with. I had a amp that was rated for 2 ohms but only suggested fro 4 ohms in mono. It ran much cooler under the 4 ohm load. Granted the subs had a little less punch (barely noticable), but not enough to justify risking heat damage.

If quiters never win, and winners never quit, who the heck came up with the idea that you should quit while your ahead?
I am using kenwood kac-ps301t. Two channel amp. Woofer is kenwood xw1225db
Connection type:
1. Two channel mode, at 2 Ohm will produce rms 200w X 2 =400w.
2. bridge mode, at 4 Ohm will produce rms 400w X 1 = 400w.
Will it be the same output for both of the connection?
You will get the same amount of power either and performance either way. You can either wire each sub in parallel to it's own channel on the amp (top diagram)
