Can someone tell me how you correctly strap 4 mono amps together for me using a quad 2ohm sub.

I've tried doing a search but nadda. Termpro's search isn't even working right now either.

How do ya wire em!? [img]graemlins/dunno.gif[/img]

and if you're feeling like pullin some jazzy reply, Microsoft Paint it up and draw a diagram! pwease?

My guess would be either,
Strap 2 amps to 2 coils @ 1ohm and do the same to the other coils, or strap 2 amps to 2 coils @ 4ohms and the same to the other two coils.

 

Correct me if I am wrong but would it not be better to just run 1 per coil and match your gains and I would like to know that aswell I thought you could only strap 2 amps together but we'll see

See no periods.... [img]graemlins/laugh.gif[/img] sorry about that man how is the spling?lol

 

Well we'd have to know what impedance the amps likes.

The reason you can'thave one amp per coil is because theres a conductor limit of 4.

Quad 2ohm sub.
and each amp puts out 1200w @ 1ohm

If I knew how amps strap together, I would guess that you could wire it like 2 DVC subs and use 2 amps per 2 coils.

But of course I don't know what I'm talking about...

Beer me.

Well which amps are they? Can they be strapped?

If you can strap them then you could try them at 1 ohm per pair if it works.

When you strap 1 ohm amps they end result is a pair of amps that put out at 2 ohms.

Or if DB Steve doesn't have a fit you could try these little fancy boxes that I'm waiting to get it!

I think the answer u are looking for Bidnyk is to have one master amp and one slave amp (thats if they are strapable)
set one in zero (0-180 phaze) and the other 180

then put your speaker terminals - to - and your plus + one on each coil (yes one + to negative and one to positive for probably 2 ohm cause your amp are 1 ohm each together at 2 ohms

Then u hit the other coil to get u a 1 ohm load

grab 2 more amps and do the same , good luck man see ya soon

PM if u need more help

 

any mono block is strappable

 

Any mono block is not actually strapable, I wish they were and I would be strapping everything. Even the bridging modules that are out there do not make every amp strapable.
Best thing to do is to find amps that are strappable, there are alot of them out there now and then you know you have amps that have been tested to work properly in that application.
One tip: You have to make sure that each amp still needs to see a load it can handle and the final impedence gets halved between the two amps.
So if you have amps that can handle a 1 ohm load each, you need to have a 2 ohm coil for the two of them, so they each "see" a 1 ohm load.

 

^ actually no, you can bridge any two monoblock channels quite easily...

If the amps fit this criteria you need a bridge modual or a phase switch.... run one amp 180 degrees out and connect +ve out on both amps to either side of the sub coils...


since this is for SPL app it is quite common to run well below rated load for the amp because of impedance rise at resonance... just watch it for daily driving...

Edit: it can't hurt to measure impdance rise or to bench the amp to see what its got below rated load when deciding on wiring configurations...
