Wiring for a 4 ohm question

Ron-P

My Tempest is a duel-voice coil driver. I want to wire it up for a 4 ohm load. So...

Would I wire both (+)'s and (-)'s together and then run 1 set of wires to the 5-way binding posts on the sonotube?

Then, with only one set of binding posts on the sonotube, would I run both right and left channels out of the amp, combine them together and then connect the now 1 set of speaker wires to the binding posts?

I'm 99% sure this is what to do, just want to double check with the pros.

First, is the dual coil rated at 8 ohms each?? If so, yes you wire them parallel as ohms law states that "if 2 like resistances are parallel, the total resistance is half the rating of one resistance rating".

Secondly, I would not suggest you combine the amp outputs and hook them to a common load. I would suggest bridging the amp which effectivly puts the amp outputs in "series" internaly and allows you to drive lower impedence loads.

Simply paralleling the amp outputs could possibly damage the amp or the drivers, espicially if it (amp) is not intended for that type of wiring configuration.

Let us know the outcome.

Peace.

Well, the amp came last night and low-and-behold, there is only one set of speaker outs because it is a subwoofer amp. So, that answered that question real easy.

And yes, both are 8 ohm coils. Thanks Joe!

What amp did you get Ron?

Thought you where using the Velodyne amp?

Ron-P

No on the use of the Velodyne amp. I picked up a Plate Amp from MCM Electronics for $105.00, 250watts. Besides, when the sonosub is done, I want to sell my velo and recoupe some of the cost.

Are you going to mount the plate amp to the sono tube? I have seen it done but it looked tricky.

I am ordering my driver today and will start my project this weekend.
