I have two subwoofers.

Each subwoofer is 2 ohms.

I have two amps that are 1 ohm stable and capable of strapping.

Is this the correct speaker wire strapping configuration:

connect the master amp + to subwoofer 1 +

connect the slave amp - to subwoofer 2 +

connect subwoofer 1 - to subwoofer 2 -

Will my amps be putting out 1 ohm power with this strapping configuration?

What are you trying to do? Are the subs dvcs or svcs? I would just run an amp to each sub wired to 1 ohm given that the subs are dvcs....

If they are 1 ohm stable alone each amp, the lowest you can go strapped is 2 ohms.

For strapping the majority of amplifiers, this is how you do it, unless manual states otherwise.

But being you dont have the amp brand/model listed there is only so much that can be said.

When you strap 2 amps together you connect negative speaker outputs from one amp to the other.

Its normally best to keep these negative jumper wires from amp to amp 16inches or less, and you can use both negatives if you want from one amp to the other.

The Master amp is the amp that your main rca's go into from the headunit, sometimes there will be a master/slave switch. Leave it as master.

The slave amp is the amp that you have the jumper rca running too, and if there is a switch flip it to slave.

You will not use any of the settings on this amp normally.

The master amps positive speaker outputs connect to the positive speaker wire on the woofer.

The slave amps positive speaker outputs connect to the negative speaker wire on the woofer.

*****When you have a pair of 1ohm stable amps strapped together, the lowest stable ohmload of the amplifiers is now 2ohms when strapped. This is the same as if you bridge a 2 channel amplifier that is only stable at 2ohms per channel, but when its bridged it is only stable at 4ohms mono.

So if you wire your woofers for 2ohms for the strapped pair of amps, each amp will be acting as if it was wired at 1 ohm still.

The subs are SVC. I want the amps to see 1 ohm so I get more power out of them. Hence the reason for strapping.

If you wire Two 2ohm single coil woofers together you will be at 1ohm strapped, meaning 0.5ohms per amp which is lower than their stable ohm rating of 1ohm.

Chances are if you dont have the proper electrical, and depending on the amps, and woofers. Something is going to be going up in smoke very soon.

what amps are we talking about?

some amps do great at .5 (my 1400s love it!)

but other amps can't handle it!

your electrical is another thing.

if.your amps.draw 150amps at 1ohm they will almost double that draw at .5


jvc deck

stinger 1800 front

hc 2000 kinetic rear

2 runs of 1/0g

big 3/4

ct 60.4

2 ct 1400.1

ct EXO 15 d1

lots of deadner

type r comps front stage

6 kicker tweets rear stage

lots of great stuff

coming soon

more bats

ct comps for front stage

more deadner

sweet amp rack

lots of L.E.D lights

new deck (thinking 80 prs, or flip out)

I have a S4.1000.D and A1800 only one amp has master/slave switch. How can I strap these 2 amps to be at 2ohm stable without blowing up my car. I think I have an idea. Other then that I really don't want to end up buying a new car and sounds.

You do not strap two different amps.
