Thought about bridging my hertz amp. The rear channels are 150x2 at 4 right now. If I bridged to 4 ohms it would be 250x2. Running Ddvo6x9 , fairing by speakers are mmats and ddb3. Input?

 

500W x 2 @ 4ohms.

 

if you bridge 2 rear channels you end up with one channel
id run the hertz at 150 to each DDVO 6x9 and set xover at 70
the louder you go, the hgher you will need to set your hpf
depends what ur after i guess
if you parallel them speakers to one bridged channel, your presenting a 2 ohm load, amp bridged is only rated for 4 ohm load minimum

 

You won't be able to bridge the channels for the rear speakers and parallel the speakers to run in mono as that would of put a 2 ohm load on the bridged channels. 2 4ohm speakers ran in parallel will equal a 2 ohm load

 

Don't want to bridge that amp bro! As respect said 500 x 2 @ 4 ohms. None of your speakers need that kind of power.

 

Then it would be a 2 channel amp.

Cant do what you are trying.
