need some impendence help (pics)

[Crzy 10+ year member]

ok so i followed a diagram on another audio forum to wire my DVC 4 ohm subs to 1 ohm. so today i rewired the back from 16 guage to 14 since i had 14 guage left over. i decided to meter the coils to see what they actually were, turns out each sub reads 2 ohms. jumps from 1.9 to like 2.4 stays at 2.0 for a bit type deal. so how can i make it so my amp sees each sub at 1 ohm and not 2?

It says that for my type-r's too but when I wired it all up and tested the terminals on the box...it said a final impedance of 1ohm...meh...I really have no clue but as long as it came out correct I didnt care much of it...

4 ohm dual subs can only be wired to 2 ohm or 8 ohm (talking about a single sub set up)

EDIT: nm, i think you're talking about 2 subs, try using the wiring diagram on this forum?

yes i have 2 subs, so how shoud i wire it to the amp? each in their own terminal or a bridged type setup, or each to one terminal?

bump anyone? how should i wire the 2 subs to amp to get 1 ohm impendence?

You can get down to 1 ohm as a total for both subs together. But you can only get each individual sub down to 2 ohms. so take the subs as the are now (2ohms) and paralell them to the amp and it will see 1 ohm

so both subs hooked up to one of the 2 outputs? sorry still sorta new to this

 

[project f-150 10+ year member]

yes... if you put both sets of positives and negatives together from both subs you should read 1 ohm. but by you saying put it on one of the two outputs i'm guessing your using a 2 channel amp? If so you have to to make sure it is bridgeable and wire it up the way it wants for a bridged connection. Only thing to be careful with is most 2 channel amps will not run at 1ohm mono(bridged). So running at 1 ohm could send the amp into protect if not damage the amp.

Am I the only one that noticed he is using a DC multimeter? Wire all 4 positives together, and all 4 negaties together. then hook any one of the pos and any one of the neg up to you amp

Also the only real way to test your ac resistance once all is said and done is to measure the Voltage AC while playing a 60HZ tone, then take a current reading and use Ohms law to calculate.

no its a mono, but it has 2 outputs?

from what I just saw that amp is only 2ohm stable...

Nevermind, 500W by 1 @ 1ohm

ok then the answer to your is yes and no. Yes you could wire it to just one terminal and show the amp 1 ohm. but on that amp the two terminals are actually connected together inside the amp. so to keep the install cleaner just take one of your subs wired at 2 ohms and connect it to one side +/- and then take the other 2 ohm sub and wire it to the other +/-. and your all set

so basicially its a mono block, but split the mono to 2 outputs for cleaner install of 2 subs?

thanks for your hekp guys so justw ire it as normal and it will see 500 watts each sub theroetcially if evetrythign goes right. cant wait //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
