help wiring mono amp

[gobraves00]

i have a mono amp that is good down to 1 ohm
i have a dvc 4 ohm 15 inch speaker
on the amp there is 2 sets of speaker inputs, 2+'s 2-'s
1.now can i hook up each VC to its own speaker inputs, and if so is the sub now running at 2 ohms
2a. or do i need to splice both +'s and both -'s before the speaker input and then use only 1 of the sets of speaker inputs
2b. if i need to use the second setup should i bridge it, for sum reason i remember sumthing about a mono amp works the same bridged or not
any help would be great, im getting ready to rip all my audio out again and wanna get wiring diagrams done before i start the build

[gobraves00]

this diagram gives me an answer sorta, its just that the amp in the pic only shows 1 set of speaker terminals, where has 2 sets

most mono amps that have 2 sets of terminals are internally bridged. I would wire it like you would if it only had 1 set of terminals and go with it.

if you told me the amp model# i will find everything for you i used to work at two stereo shops

[gobraves00]

Its a bostwick da1200hc
ive searched everywhere and cant find anything
that diagram is interesting to me jimmy, ive never seen it hooked up that way
so the speaker is dual voice coil, so the neg term goes to one voice coils neg, and the pos term goes to the other voice coils post term, then the neg and pos that left over i just hook awire connected them?will this bring it to a 2 ohm load since its a dual 4ohm speaker.
the reason i am asking is because i have two of those amps and 2 15's, right now i have 1 speaker to 1 amp, each voice coil is hooked up to its own terminal.it works fine, but i keep second guessing whether or not its hooked up right.im also considering adding 2 more 15's, so before i do that i wanna be real clear on the wiring.

I just realized I posted the wrong pic, but you are correct gobraves. pos to pos then to a pos terminal, neg to neg then the matching a neg terminal. That should give you a 2 ohm load at the amp.

There are two sets of terminals on the to add in more wiring options. You have d4 subs now. With this style you can add 2 d4 subs to the same amp, instead of either needing to replace the subs with d2 coils or getting a new amp.

cool, thats what i thought
jimmy, u doing any shows anytime soon
have anything setup with your term lab?

if you wire the speaker like it is above in the second post, each speaker will be at an 8 ohm load because they are in series. Then when you put them together on an amp bridged they become a 4 ohm load.

If you wire it positive to positive on the speakers coils and negative to negative and then run it to the terminal on the box. then youll get a 2 ohm load, which will give you a 1 ohm load when bridged. So you need to know what ohm load your amp can run.

I really dont spend much time in atlanta anymore, but I can get you hooked up pretty cheap with my brothers shop. as soon as I can get him the meter and software I will let you know.


I know I posted up the wrong pic, thats why I mentioned it in my last post. If you bridge the terminals on the amp then it should drop the load, but by using 1 set of terminals, it should remain a 2ohm load.

you cant bridge a mono amp though, even if there is 2 outputs. Thats the whole point of mono.

[gobraves00]

i remember once saying that you can though cause its a mono, cause no matter how u wire it still mono, idk, thats why im asking

jimmy where u stay at

its still only 1 channel, but with 2 sets of terminals. Imagine it being like a 2 channel amp. its good at a set load using 1 set of terminals, and another bridging the channels. This is the same way. Using only 1 set its like a standard amp. Using both sets(wired like you would a 2ch amp) its internally bridged requiring a different load.

[gobraves00]

whats wrong with this setup, would this work

and what ohm load would it be?

[b@d @pple]

mono amps with 2 sets of terminals are internally bridged

[gobraves00]

thats what i thought
is this diagram right and if so whats the ohm load the amp will see
they are dual 4 ohm

[b@d @pple]

if you have one 4ohm dvc sub and you wire a positive from one coil to the negative of the othercoil,and the remaing positive and negative to the amp,the sub is in series which will give an 8 ohm load

if you wire positive of one coil to positive of the other coil and negative of one coil to negative of the other coil the sub is parallel and will see a 2 ohm load...if your amp is stable at 2 ohms then parallel the sub to recieve its max output
