suggestions to connect a dual coil sub

makanaka · 12th August 2008, 22:22

hello friends
today i replaced my old sony subwoofer with a brand new pioneer TS-W307D4, now this sub has got a dual 4 ohms voice coil and has got 4 connection terminals, a positive negative and then again one more positive and negative terminals, now please tell me how to connect my sub to my amplifier, which is the best possible way to connect it, i mean in 2 ohms or 4 ohms or 8 ohms and right now iv got only one positive and one negative wire so how am i gonna connect it, iv got no idea so explain please and please keep in mind that im using a sony 4 channel XM-ZR604 amplifier, with 2 channels to support my 6 by 9 rear speakers and 2 channels in bridged mode to power my sub and im using a ported box made with mdf 3/4 inches thick in size with 15*14*13 dimensions(inches), im new to this so kindly bear with my ignorance

You amp is best suited to drive a 4 ohm sub when bridged. The sub you have can either be wired in 2 ohms or 8 ohms. If you wire the sub to 2 ohms your amp will over heat, if you wire your sub to 8 ohms you amp will not provide enough drive.

options
1. change sub to a SVC sub of 4 ohms or DVC subs having 2 8ohms or 2 2 ohm coils.
2. add/change amp to monoblock for sub capable of driving a 2 ohm load
3. use amp to drive one one coil of sub and short the second coil. this is not recommended as it can cause distortions but it wont damage the sub so it can be tried.

i dont wana change my sub and if possible my amp too, so tell me which is the best possible way to run them in accord right now and how, in detail please

you can explore option 3 given by navin then
otherwise you may also be able to use all 4 channels for the sub.
but then you will have to connect the 6*9 directly to the HU

if its possible to use all four channels of my amp to drive this sub im ready to do that, but i dont think its possible coz of 2 reasons, first is that there is only one lpf filter for 2 channels which are currently driving my sub, the other 2 channels have a hpf and no lpf the ones which drive my 6by9, so is it possible to use all the 4 channels to drive this sub, it just might be coz the sub can produce frequencies from 18 to 500 hz so even if there is no lpf the sub wont be able to produce these sounds, right ????? second reason is that i think all the 4 channels of an amp should not run in a bridged mode, i mean in either ( option 1) 4 by 2 or (opton 2) , 2by1 + 2by1 . confirm if im correct or post suggestions please, if i run my sub in 2 ohm mode in low to moderate volumes will it still overheat my amp or cause any damage????

Gunbir and Mr Rana are your men...catch them

You can wire two channel of the amp to each of the coil of the sub. Use the rest two for the speakers.

the amp is not a high power one. it will barely drive the sub this way but yes it will work.

I agree with Navin Ji since he has a 4 ohm he can use the bridged channel and wire the sub. But he will have to set the gains accordingly.

can i use all the 4 channels of my amp to drive my sub? i mean bridge them in 2 by1 and 2 by 1 and then join these 2 bridged channels to both of my voice coils?????? is it possible, i can join my rear 6 by 9 directly to my head unit, im sorry guys im really new to this so please be a bit patient, just trying to learn from u guys
