thanks for tha help, i want to bridge for more power but i dont really know what the ohms are on my subs....all i got is...

resistance is 2x3.2 ohms then

nominal impedance is 2x4 ohms...

so.....

nominal resistance is 4 ohms + 4 0hms that means each coil is a 4 ohm coil so the above diagram is 1 possibility. It really depends on the amps minimum ohm load that it can accept.

Wire it like the picture...I'd say that its the best way. The NOMINAL impedance is 4ohm. so you have dual 4ohm speakers. MOST(95%) two channel amps that are bridgeable have a minimal of 4ohm load when bridged...or 2ohm stereo (not bridged). So use this set up.

Icearrow6 is correct , most bridgeable 2 channel amps are 4 ohm bridged. JL is 1 exception that comes to mind right away though, (just not a huge fan of JL) good product, but too spendy for me lolz

You will have to wire the speakers in series for an 8 ohm load. You will not gain any power at all.

alright...if I bridge the subs and have both of them on 1 channel...how many ohms is the amp pushin out...

Te picture shows a series/parallel setup. The speakers are first in series and then parallel to the amp. You are getting a total of 4ohm load on the amp. This is the ideal setup for the "bridge" on your amp.

Bridge = 2 separate channels into a common load. You can not bridge it on one channel.

It depends on how you have the speakers wired (Series or Parallel) as to what ohm load the amp will be seeing.
