wiring a dual voice coil sub?

[sweeteffx]

I'm new to the whole dual voice coil concept. I have an MTX thunder 8000 dual voice coil sub (1000 MAX/400 RMS). I want to know the best way to wire my speaker for the best output. I have a 2 channel amp that can be bridged
The amp works:
2-4 OHM in stereo
4-8 OHM in bridged

I know that there's a way to run the sub parallel or series. But which is which? + to + and - to - is parallel i guess?? and is the series + to - to + on the amp and - to + on the - terminal on the amp?

Or would it be best to run them independant? each coil as a different sub on the amp? coil 1 as left and coil 2 as right? Or would that mess it all up? (forgive my ignorance) :oops:

Does the amp have two 4ohm coils or two 2ohm coils? Some also have 3 or 6 ohm coils this is something we need to know.

I am guessing that you meant sub not amp?

Size---------------------------------------------10"
Impedance-------------------------------------Dual 4 Ohm
Frequency Response--------------------------28-150Hz
Power Handling--------------------------------400 RMS / 800 Watts Total
Sensitivity--------------------------------------84.3dB
Voice Coil Size---------------------------------2 1/2"
Magnet Weight---------------------------------102oz
Mounting Depth--------------------------------5.000"

wiring one of the - off of one coil to the + off the other coil, then using the remainding + and - to run to the amp would make your dual 4ohm int oan 8ohm load for the amp. both + together and both - together will show your amp a 2ohm load.

at 8ohm mono i doubt your amp is gona be puttin out many watts. i dont know the specs on your amp however..

if you ran each coil t oa dif chan, youre only gona receive signal from the left or right chan. cause you cant run both coils and have them on opposing channells left/right. it would have to see a mono load as in only right or only left.

you could either
a) get an amp that accepts a 2ohm load
b) buy another sub an run it 2ohm stereo into 2 subs
c) run it 8ohm mono

w/out knowing the specs on your amp i cant really say..
runnin it 8ohm will work tho, an your amp will run alot cooler

[daveb91]

Yeah I ment subs wire them 2 ohm and hook them up stereo now if you can get a mono input to the amp that would be best. Or you can wire up your subs 8 ohm and run them parallel to the bridged input for a total of a 4ohm load. Just suggestions.

[daveb91]

Though he had two. The amp might handle a 2ohm mono load if it gets extra cooling and depending on the thermal shutdown circuit it has on it will probably not last long.

some amps will handle the extra load, some will trip as soon as it hits the 1st bass note. it will def make the amp run alot hotter.. and shorten the life of it, but it may work, depends on the amp

By dual 4 ohm do you mean (2) 4-ohm coils or (2) 2-ohm coils? My sub was also labeled dual 4 ohm, but it was a dual (2) 2-ohm (4 ohm total) sub.

What? :?

[tristanlee85]

Lol. Nevermind.

[sweeteffx]

I'm gonna run it 2 ohm i spose + + + and - - -. Is that parallel?
