bass shaker hook-up! Again

[dholmes]

Okay Ive got 4 bass shakers & a plate amp for a sub, what is the best way to hook them up? I was thinking that the plate amp has a 2 spk hook-up, run the 2 positive on the amp to 2 bass shakers jump from there to the other 2 & do the same to negs. Is there a site where I can go to to figure this out thanks

What impedience is the amp rated at? What nom. impedence are the bass shakers? A little more info if you want a good answer...



Rtotal = (1/R1 + 1/R2)^-1 parallel
Rtotal = R1 + R2 series

These apply for nominal loads. If your shakers are anything like speakers, the load varies with frequency. But that wont matter for what you're doing....

the shakers are 4ohms & so is the amp.

To stay at a 4ohm load, you'll need to wire 2 separate pairs in series, the wire the separate pairs together in parallel.

Yup.... here's a rough pic

Same result, but the pic shows 2 separate pairs in parallel, then the 2 pairs wired in series.

6 of one - half a dozen... you end up at 4ohm.

Yeah I guess I should have explained that... I was working on the pic when you posted
