Wiring 4 Ohm Subwoofer To Mono Amplifier for 2 Ohms

[chartman18 10+ year member]

My question isnt too complicated, I just am not entirely sure how to do this.

I have a Type-Rawr 1242D 12" Subwoofer and a Hifonics BXi 1606D Mono Amplifier.

I know how to wire 2 Ohms on the sub, but do I wire it back to the amp on both +'s/-'s or just 1 +/- ?

Thanks. Wiring it up today.

Correct me if im wrong but you need two 4 ohm subs to wire down to 2?? I dont kno ill look for you.

No, to wire it to 1 ohm, you need a 2-ohm subwoofer.

In my case, mine is a 4 ohm subwoofer and I need to wire it to 2 ohms, but I just dont know for sure how to wire it on the amp, both terminal +'s/-'s or just 1 terminal?

Yea your right here....this should help

Thanks, but thats not what I was really looking for, lol.

I just need to know how to attach the sub wires on the amp. My amplifier has 2 sub outputs (+/- and another +/-) and Im just not sure if my sub wire (+/-) needs to go on only one amp terminal output or split into both.

Ok so its like this...

Amp

RMS @ 4-Ohm: 1 x 550-Watt

RMS @ 2-Ohm: 1 x 1100-Watt

Type R

RMS Power Range : 50-500 Watts

So you could wire the sub @ 4 ohms briged on the amp.

Its a Alpine Type-R 12" Subwoofer, 4 ohms (wiring to 2 ohms)

And my amp is a Hifonics BXi 1606D Mono amplifier.

If I wire it 2 ohms on my sub, and I 'bridge' it on my amp, does that mean Ill blow it? What does bridging do for me?

But main question is how, lol. Bridging or no at 2 ohms?

the sub is dvc people..... both postives will share a terminal as will both negatives and you will have wire it to 2ohms.

there is no bridging as that is a mono amp

Sooo.....I just use no bridging and just wire my sub to the amp with one (+|-) terminal then?

 

[Worlddre 5,000+ posts]

exactly...the amp cannot be bridged as bridging requires more then one channell

LAWL at no one understanding your question.

You just use one set of terminals. The other one just leave empty.
