How the best way is to hook up 2 400 wat amp's to 3 subs

Bridging an amplifier refers to combining the power of two channels to run one speaker at higher power. If it is wired correctly, your amplifier is running with 4 channels bridged into 2 speakers now.

Hi, you have two choices for hooking up a sub to the 4160 amp. You can either connect your sub to one of the two available channels, or if the amp supports it, you can bridge channels 3 and 4 to get increased power to your sub. You have a 4 channel amp - channel 1 and 2 go to your 3-way speakers up front, which leaves channel 3 and 4 available for your sub.

Your best bet will be to wire 2 subs in parallel to the amp. Each sub should be rated for at least 300 watts rms at 4 ohms. This will give you a total impedance of 2 ohms, and your amp will put out 600 watts rms at that impedance. That way, each sub will receive 300 wats rms. I would not recommend wiring subs in parallel, as you will need two 1 ohm subs at 300 watts rms, which are harder to find and will be more expensive. A parallel circuit is the most efficient way to do it.

run two 6x8s on each of the front channels of the amp. then depending on the sub you can bridge it on the rear channels.only if its a single four ohm. if its a dual 2 ohm sub run each coil on each channel. 1 coil-1channel. the other coil-the other channel. amp should run fine may run a little hot since it will be doing all it can do at a safe ohm load. just make sure it is mounted in a well vented area. should be safe.

If you are trying to use 3 amps to drive a single cabinet, it can not be done. Bridging amplifiers requires a specific circuit design for that application. There is no way to hook up multiple amps to a single speaker.

one of the channels your using may be burned out or there is sum wire touching inside the amp so take the cover off and make sure nuthn is touching and see if sumthn is burnt and also try using a different channel on the sub

Hi,
This should work if channel 3 & 4 are bridged at 4 ohm.
channel 1 should be stable at 2ohm
channel 2 should be stable at 2 ohm
You can hook up the right side speakers together ( + with + and - with - ) . same thing with the left side. this will give you 2 ohm each channel. this will cause your amp to run hot (this might be tuff on the amp). It will give you right (2 speakers) and left ( 2 speakers ), no front and rear adjustement if you need to balance your sound. I think you should be better buying another amp for your sub and take your 4 channels for your 4 car speakers. this amp as a rca output that can feed the other amp ( sub amp ). it is possible to do it.

Good luck

bridge it and rear channel if you need to know how to bridge let me know

That's a 4-channel amp, not a 2-channel, which makes me wonder exactly how you have it hooked up to your sub. Is the LED light on the amp coming on? How many subs do you have hooked up to it, and how is it wired?
