How Do i wire my Type R subs?

[dredey 10+ year member]

i got 2 type r 1242d (4ohm) subs

and the wiring on the manual is pretty weird

http://akamaipix.crutchfield.com/Man...500SWR1242.PDF

is this configuration really better?

and what exactly do the jumper cables do?

i also found this wiring config.

http://akamaipix.crutchfield.com/ca/...4-ohm_mono.jpg

so which one should i use thanks

im thinking the alpine manual was using a mono amp ?

but i got a 2 channel amp

i know i have the samethin posted but i think the title change will draw more answers

Hi the links you posted dont seem to work, but you want to send a mono signal to your subs so i dont know what amp you have but i presume you can bridge it.

You can wire to 4ohms or 1ohm depending on what you amp specs are.

Try going to a website like crutchfield.com to use the wiring wizard to see how to correctly wire your subs.

you can run them on separate channels. wire them to 2ohm each and then to each of the channels on the amp.

what amp are you planning to run?

 

[dredey 10+ year member]

those are the three diagrams im confused about

idk which to use

i have a wack ass boss 2 channel amp

im saving for an upgrade

but i want to set it up as good for now

cuz i dont make much money

I don't see why you are confused with those diagrams it's pretty self explanatory.

 

[dredey 10+ year member]

im not confused i just want to know which one would be best for my subs

 

[C3 Customs 10+ year member]

Best will depend on a lot of factors, your amp, charging system, your ears, your enclosure, crossover freq, your car acoustics,....what I can say is this if you want to optimize your amp performance you can bridge the amp and run the subs in series with each sub wired in parallel so that your amp will see a 4ohm load.

wouldnt this setup give me 2 ohms

so wouldnt that give me more power

the first pic i put the 2 DCV 4 ohm 2 channel in parallel

 

[dredey 10+ year member]

wait doesnt 2 ohm mono = 1 ohm stereo so both of our setups would be the same?

wait doesnt 2 ohm mono = 1 ohm stereo so both of our setups would be the same?

each sub in parallel = 2ohm sub, 2ohm sub

when the subs are wired in series you add the resistance 2+2=4ohm

when you bridge a 2 channel you get a mono amp but that does not increase or decrease the ohm load that is presented to the amplifier.

so how can i bridge my 2 channel amp and get 2 ohms out of it with the type rs

im guessing 2 ohms will give the most power

the audioque 1200 d is stable to to 1 ohm

so ican do that to right, without harming my amp or subs

these are the specs..

youll get much more response wiring to a 2 ohm load than wiring to 8 ohm

 

[dredey 10+ year member]

what about wiring to 1 0hm

also i just read this whcih is saying 8 ohm is better

the lower the final impedance (ohms) at the amp the lower the sound quality but the easier/cheaper it is to power

most amps are not stable below 2ohms so they would run hot and go into protection a lot

one DVC 4ohm sub can give you impedances of 2 or 8ohms at the amp

one 2ohm DVC sub can give you impedances or 1 or 4ohms at the amp

an 8ohm final impedance at the amp will give you better sound quality than 4ohms but it will cost about twice as much and you wont really be able to tell because most of your sound quality should come from your inside speakers
