First of all, any testomonials about this amp?

I have 2 400W RMS, 600W max, 4ohm 10" Kenwood subs. They're sorta old, probably from the 90s so I think they're single voice coils.

if you look at the specs of the amp here:

it says that bridged, it can do 400W x 2, which would be perfect for my subs right? however it says that it's stable into 4 ohms in mono mode... my subs are 4 ohms, but I also remember reading somewhere that when bridged, a 4 ohm load reads as 2 ohms to the amplifier. can someone verify this? would the amp be stable running 400W monoi bridged into 2 separate 4ohm subs?

 

I can help ya here. I have the 600a4, two channels running my components, the other two channels bridged to one sub. I will assume you want to bridge your amp from 4 channels to 2 channels.

Since you have 2 subwoofers, each one being 4 ohms, you should bridge the front channels (left & right) together and put one sub on it, then bridge the rear channels (left & right) together to power the second sub. You will NOT connect the two subs together; they are run independently of each other.

In this configuration, you will put a 4 ohm load on each bridged pair of channels, which is FINE.

Hope this helps.

 

jhargrove is right. you are not bridging the subs together. you are bridging the channels on the amp.

so you would want this:

ch 1 = positive from sub #1
ch 2 = negative from sub #1
ch 3 = positive from sub #2
ch 4 = negative from sub #2
