Wiring Two subs together?

[rys272]

Before I hook this up I wanna make sure I got em wired correctly?

2 channel 1000 watt amp
Two 12” Subs

So I’m gonna have the subs going to the one channel and extreme hack wiring diagram but this is how I have them wired as of now is this even close to correct?

That looks to me like you are trying to run two speakers in parallel which would make the load 1/2 of what the speakers are labeled as in two x 8ohms in parallel is 4 ohms 2 x 4 ohms parallel is 2 ohms. You need to see what load your amp is supposed to have too low of a load will short an amp. If you wire them in series 2 x8 ohms would be 16 ohms 2x4 ohms would be 8 ohms

So if I’m wiring speakers into this amp
They should be 2/8 ohm but if I’m doing subs or “bridging amplifier” my connection needs to be either 4/8 ohms

I’m basically looking for the safest way to wire these but still have them fairly kicking.

ask chat gpt, i bet it could tell you.

Those aren't the best pics but those look like dual voice coil 4 ohm subs. The way you have your diagram will put a 1 ohm load on the bridged channel of the amp. High quality amps usually are 1 ohm stable. Drive em hard and they will get hot. I'm curious to see the enclosure and how you plan to mount them...

Yeah they are DVC 1000 watt 4 ohm subs, gonna make box behind seat. Seats gonna have to come forward a lot but I’ll have to make it work lol.

Would this be a better way of wiring them?

Also would under powering them do anything bad? Or only if you overpower

To wire your Sony XM-N1002 (2-channel, 1000W amp) to two 12" subwoofers, we need to consider:

1. Subwoofer impedance (ohms) – Are your subs 4-ohm single voice coil (SVC), 2-ohm, or dual voice coil (DVC)?
2. Power handling – What’s their RMS power rating?
3. Wiring options – Whether to bridge the amp for more power or wire the subs separately.

Amp Specs (Sony XM-N1002)​

• 2-Channel Amp
• Max Power: 500W per channel (1000W total)
• RMS Power(real power):
  • 70W x 2 @ 4Ω
  • 85W x 2 @ 2Ω
  • 175W x 1 @ 4Ω (Bridged)

Wiring Options for Two 12” Subs​

Best Option: Bridged Mode (If Subs Are 4Ω SVC or 2Ω DVC)​

Wiring two subs in parallel for a 4-ohm final load (for best performance)


Most power from the amp (175W RMS at 4Ω bridged)
Works best with two 4-ohm subs (SVC) or two 2-ohm DVC subs


How to wire:

• Connect both positive terminals of subs together, then to the amp's + (bridged terminal) on the RIGHT channel.
• Connect both negative terminals of subs together, then to the amp's - (bridged terminal) on the LEFT channel.
• Set the amp to LPF (low-pass filter) for subwoofer operation.

Diagram:

Amp Right + (bridged) → Sub 1 + → Sub 2 +
Amp Left - (bridged) → Sub 1 - → Sub 2 -

---

Alternative: Stereo Wiring (If Bridging Isn’t an Option)​

• If each sub is 4Ω SVC, wire one to each channel.
• Each sub gets 70W RMS (less power than bridging).

How to wire:

• Sub 1: Connect + to the amp’s Right +, - to amp’s Right -.
• Sub 2: Connect + to the amp’s Left +, - to amp’s Left -.

Diagram:

Amp Right + → Sub 1 +
Amp Right - → Sub 1 -
Amp Left + → Sub 2 +
Amp Left - → Sub 2 -


This setup is weaker than bridging but easier to wire.

Which Setup Should You Use?​

• If you have two 4Ω SVC subs → Bridged mode (175W total) is best.
• If you have two 2Ω DVC subs → Wire them in parallel for a 4Ω final load, then bridge the amp.
• If you have two 8Ω SVC subs → Use stereo mode (each on a separate channel).

---

Final Tips​

Use a proper power wire (at least 4-8 gauge) to prevent voltage drops.
Set the amp’s LPF filter (80Hz recommended) to keep it from playing high frequencies.
Check your subs' impedance before wiring!


Do you know the exact impedance of your subs (SVC/DVC, 2Ω/4Ω/8Ω)? That will confirm the best setup.

This is a visual. For me...less is more. If you want something musical, like a 4 Ohm set up. 1 ohm you are just gonna get you and your car rattled, especially the car 3 places from you. So all about what you're trying to accomplish.

Really nice site for 12 volt A/V stuff: https://www.the12volt.com/caraudio/subwoofer-wiring-diagrams.asp

Will supply all you need to know about subs and wiring. Just make sure your Alt-Batt-Wiring are capable of sustaining your amps power needs. I see no mention of your current electrical system. For example, a '85 comes with a 63 or 78 amp alternator in most cases and using this streetwise method of ( AltAmps x10 ) will give the approximate RMS maximum of what you could run but keep in mind that you have other electrical items that need to be figured into that equation as well. Ya never want to cause undue strain on the alternator.

Yeah I want them more musical don’t care about it shaking the whole truck, so go with that middle diagram?

I'd follow the read from @CountKrunk.
We know you have two DVC subs, but what ohms? Seems like you're gonna want amp bridged mono and run subs in parallel if at 2ohms each. Don't just pick a diagram...
