Please help wiring subs for vehicle use
      #1036804 - 06/03/13 09:43 PM
Hi Everyone

Hope we all doing well

I Can't Seem to get this right.

I want to get 2x Pioneer TS-W309D4 1400W DVC Subwoofers. Now they are 400W RMS and rated at 4Ohms:
http://www.pioneerelectronics.com/PUSA/Car/Subwoofers/Champion+Series/TS-W 309D4

Now most of the monoblock amps i have found are 3000w but then only 380w RMS @ 4ohm and 750w RMS @ 2ohm so now i have found a 9000W mono but 1800w @ 1Ohm Targa Viper 9000:
http://www.autostyle.co.za/car-audio-1/car-amplifiers-crossovers/targa-180 0-rms-1-ohm-amplifier.html

(I am from South Africa hence the autostyle site)

I have found the wiring diagram to wire them to 1Ohm at:
http://a248.e.akamai.net/pix.crutchfield.com/ca/learningcenter/car/subwoof er_wiring/2-DVC-4-ohm-mono-low-imp.jpg

And 4Ohm at:
http://a248.e.akamai.net/pix.crutchfield.com/ca/learningcenter/car/subwoof er_wiring/2DVC_4-ohm_mono.jpg

Now considering the 2x 400w rms subs and the 1800rms 1ohm amp how would you recommend wiring it so i don't blow anything and have the best sound?

4Ohm on the amp will push out 650W... is that right?

Thanks for any and all future help

Car audio isn't really what this forum is about... and you already seem to have the appropriate wiring diagrams to connect your dual voice-coil speakers in such a way that they present a 1 Ohm load to your amp.

So I don't really understand what you're asking, or why you're asking it here.

Hopefully you'll have your car's body panels shaking and rattling excessively very soon!

Thanks H

My thing is that the subs are 2x 400W with 2x4Ohm coils each. The Amp is 1800W at 1Ohm which would cook the subs... now if i go to 2O then i have around (im guesssing) 1200W which is still a tad strong. 4Ohm is around 650W which is now too low i assume, and there will be clipping, im asking how to wire them in such a way to get the best quality and power without cooking anything.

The Amp that i showed is a 9000W amp (which is 1800W at 1Ohm) is that too high? there is a 4000W that is 500w RMS at 1Ohm so what do i do

Thanks
Yubbz

Then don't turn it up full!

The amp manufacturer should give ratings for higher load impedances. Generally, it is better to have more power on hand than the speaker's rated power.

If you can't find anyone with specific experience of these components in a car-audio application, then I would suggest experimenting with differeing wiring arrangemetns to see what works best.

I'd suggest starting off by wiring them for a 4ohm load (wire the two coils of each speaker in series to give 8ohms per speaker, and then wire the two speakers in parallel to give a four ohm total load to the amp.

Depending on how well that rearranges your internal organs, you could then re-wire to try a 2ohm load (wire to only one set of coils for each speaker, and wire the speakers in parallel), or the 1 ohm load (both colis in parallel, and both speakers in parallel).

You'll probably find this forum of more specific help:

Thanks H

This will Help a lot...

One last thing.... do you think this is overkill for 4x 50Rms 4way speakers?? im after a good sound system, not an organ remover :P

Thanks

I'm not an expert in car sound systems I'm afraid, and I've never really seen the point in spending vast amounts of money on specialist 'hi-fi' equipment for use in an electrically and acoustically very hostile environment, which is easily steal-able, and one in which excessively loud music will potentially distract from the life-critical role of driving.

I like good sound, I like to listen to music while I drive, but I'm yet to meet a factory-fit install that wasn't adequate for that purpose...

As I said, I think you will get more relevant and supportive advice from a dedicated car hifi forum and website. But I hope you achieve what you are trying to do and wish you good luck with it.

Interesting - I've yet to meet one that is...

That said, I probably have at least one order-of-magnitude less amplification than the OP.

Small and highly resonant environment with atrocious standing waves, vibrating surfaces, and an ambient noise floor above 55dB SPL on a really good day. Not exactly a quality listening environment, is it? And more power really isn't the answer...

I find the stock car audio system useful.
When I can't turn it up loud enough to drown out the graunchy rumble, it means I really DO need to change the wheel bearings.

Factory fitted systems have come on in leaps and bounds in the last 25 years. When I was younger, the first thing I would do when I bought a new car would be to put in a decent stereo and wire up my B&W LM-10 speakers. I haven't felt the need to do that in the last few cars I've owned.
