Best way to wire 4 channel amp.

[systembumping 10+ year member]

What's up, I just got an Eclipse 3640 4 channel ampthat I am going to eventually hook up to my components but for right now I am using it for my subs (2 mtx thunder 6000 10's) and I wanna now what's the best way to wire it to get the most power into the subs. Thanks.

What's the impedance configuration of your subs...

 

[systembumping 10+ year member]

There 4 ohm I believe.

SVC or DVC?

 

[systembumping 10+ year member]

They have 2 sets of thing to hook the wires to but I looked on ebay and it said single voice coil, I bought them used so I really dont know. All I really know is there wired to 4 ohms.

Can somebody tell me.

Cant tell you anything if we dont know if your subs are dual voice coil or not.

Can you post up some pictures?

They are dual voice coil, I just asked the guy I bought them from and I looked on the website, and I don't own a digital camera.

The Eclipse is not rated for a 2ohm bridged load so this is the way you want to wire it.

Wire each sub like this and connect to each bridged channel.

OK I appreciate the help Stone, you always looking out.

Hi folks,

I know this is an old thread but I don't want someone to read this erroneous info and wreck their system. I'm not sure why nobody else realized this...

Here are the specs for that Eclipse amp, it's the same as the 36401...40x4 watts at 4 ohm, 60x4 at 2 ohm.. If you bridged it you could drive 2 Ohms at 120 Watts max 2 channels.

I never even heard of an 8 ohm car audio system. 8 Ohms is mostly reserved for home stereo equipment.

Chances are they are 2 Ohm coils so hooking them in series would yield a 4 Ohm speaker. If you wire the 2 coils in parallel you end up with a one ohm speaker then you could wire the duals in series for a 2 ohm load. That is if you want to run a mono amp at 2 Ohm. 9 out of 10 times you would want to run the right channel output to one coil and the left channel output to the other coil on each speaker so both speakers would reproduce the bass from both channels simultaneously. If you connect the voice coils up in series on all 4 coils in series for 8 Ohms like suggested I don't know what one would expect.? Probably wouldn't get much sound from the 4 coils in series for 8 ohms. That may even blow your outputs from to low of a load if you hammered on it trying to get them to bump. Having the wrong impedence is almost as bad as a dead short or free wheeling open loads allowing the outputs to run away as they say. Most amps are protected against that these days though...

Good luck with your 8 Ohm car audio installations. Actually I do remeber a mobile radio that used an 8 ohm speaker but it was a Realistic CB radio from Radio Shack from the late 80's, not a car stereo...

Just a thought....

Really?

You just brought back a thread that has been dead for six years and you are absolutely wrong.

First the amp bridged is not stable to a 2 ohm load. When bridged it is rated at 120Wx2 into 4 ohms, trying to use the amp bridged into anything less than 4 ohms is only asking for trouble.

Second dual voice coil 4 ohm drivers are very common in car audio. Since the OP was using a four channel amp bridged to two channels the only safe way to wire the dual 4 ohm subs was to wire the two coils in series for an 8 ohm load with one sub on each of the bridged channels. The higher impedance will not harm the amplifier just cut it's output. He will be seeing 80Wx2 instead of 120Wx2. Technically if they were dual 2 ohm drivers you would wire them exactly the same way so each sub has a final 4 ohm load.
