Bridging AMp

I'm pretty sure you can do it but just to be sure do you have the model # or do you know how many ohms each sub is also are they DVC or SVC?

lol I knew that sounded like a Pioneer model number.... anything with DEH is always gonna be pioneer.

As for the bridging question, it all depends on what kind of subs they are; i.e. whether or not they are DVC, and what impedence each voice coil is.  Most likely you can bridge the 4 channels into 2 channels, and as long as the subs have voice coils of 4 ohms or higher you will be alright.  Or I guess if you had 2-ohm voice coils you could wire them in series and then run that bridged to two channels, but best way to do it is with a dvc sub that has 2 4-ohm voice coils.

I;'m guessing those pioneer subs are not DVC, in which case you will definitely be able to run them bridged to the amp with no problems.
