Wiring and install question

[drewbillingsley 10+ year member]

I just bought a dual 2 ohm sundown sa15, and a spl 1600w amp that if bridged at 4 ohms will produce 740w. So the shop told me to wire the sub at 4 ohms and bridge the amp. Can and how do i do that?

you wire the sub in series meaning wire positive coil 1 to negative coil 2 them them take neg. coil 1 to neg on amp and pos. on coil 2 to pos on amp

so if i wired it up the way that link says, would the amp be bridged because its wired to the positive of one channel and the negative of the other channel?

This will help you in the future as well..gives you wiring options and ohm loads..hope this helps..better to see/print out take w you, and easier to understand..

Yes the amp will be in mono/bridged mode..just be sure to set your switch from HPF to LPF and turn bass boost down to zero,and gains down and adjust accordingly

what is hpf and lpf? and it would only be putting out 140 more watts than the subs rms when bridged. why would i have to turn everything down?

High pass filter,and low pass filter...you will be generation more power going into mono/bridged mode...i say turn your gains down due to clipping/and or possibly damaging your subs just by a flip of a switch..deff a precaution measure to take/consider

well the specs on the amp say 740w bridged at 4 ohms..

 

[drewbillingsley 10+ year member]

and the amp has knobs for hpf and lpf that you can turn between 40hz and 250hz. what should i do with that? and will it be ok for the amp level to be a little over halfway?

I couldnt find anywhere specs wise that the amp is 2 ohms mono stable..just 2 ohms x2 in stereo stable, and 4 ohms mono/bridged stable..may need to call the manufacture to get the answer on that to run 2 ohms stable mono/bridged, and also look at your pamphlet/specs booklet..I cant find that..i would say its not by specs ive googled up,so i wouldnt try it,you can damage the amplifier/and or your subs too

I don't need it to be 2 ohms mono stable. Its a 2 channel amp that im going to run bridged at 4 ohms with a 2 ohm sub. The amp is a spl z2x 1600.

I think you need to search some manuals or guide in connecting this one so that it will be easy.

I think i pretty much know how to do it now. Looked up a few diagrams and i understand em for the most part. But someone give me a definite answer, u can wire a 2 ohm sub to a 4 ohm load without hurting it right?

HUH?

u have a 2ohm Dual Voice Coil sub. u have two (2) voice coils in your sub that are a 2 ohm resistance EACH! THE SUB IS THE LOAD

You wire both voice coils in series to create a 4ohm load to the bridged amp.
