Odd Sub Wiring?

[Cpyder 10+ year member]

Can you wire a 4 channel amp to a single voice coil subwoofer?

yes but you can only use two of the channels

ummmmm.............. it might work for a while but it doesnt sound safe.... lol parallel it all.

ummmmmmmm why would it not be safe?? unless he has a single 2 ohm sub and the amp is only 4 ohm stable bridged there won't be any problems. perfectly safe duh

You can bridge the amp so that's it has 2 channels(which would both be stable at 4ohms and probably not much less), then run each bridged channel to the VC of the sub...I assume it a 4ohm SVC sub, right?

What sub/amp are you working with? Are you using the 4 channel purely for the sub, or are you using two of the channel for your dorr speakers as well?

you saying he can run all 4 channels to the sub?? if so i've never tried that before

I've done it before with no issues...granted I wasn't driving the amp very hard. You'll basically just have the two channels seeing a 4ohm load since they both go directly to the 4ohm VC, so you'd be safe...I assume.

might find a cheap 4 ch to try it with. always thought they would feed back into each other.

whooaaaa you saying to run all four channels to one svc? you do that with one of ur amps now. and take a video

and wats with the huge avatar?

The sub is a JL Audio 6w3v3, 4 ohm. I just installed a Polk PA500.4 in place of a Lanzar Vibe418, so now it's a spare. I'd like to use the spare Lanzar to power the JL (using all 4 channels) for some very snappy midbass up front. I know the Lanzer specs say 125W RMS x 4 or something but it's probably more like 35W or 40W x 4.

If I bridge the amp to make 2 channels and then connect both of those to the subs voice coil, will that run around 120W RMS x 1 now?

Sorry, Vibe416

Yeah, bridge two channels (Only two wires) and run them to the sub. Its a lanzar, so it probably wont be 120 RMS more like 90? The other two channels will go unused...

If you try bridging all four channels your amp will either go into protect mode or blow up....I hope for the latter.

In my experience Lanzar amps havnt really been overrated. MAybe 15-20 watts.

How were you testing that?
