wiring four 12 inch 4 ohm subwoofers

hey guys im new to this forum and car audio in general. My question is how to wire up four 12" 4 ohm subwoofers. right now i have 2 12" 4ohm 250 watt jl audio subs. i want to add two more of the same subs to this setup. i have a jvc 2 channel 250 watt amp stable down to 2 ohms.

any help is greatly appreciated, thank you

what model number subs?

what model number amp?

you need bigger amp before you plan anything further ok

wiring 4x subs depends on how many voice coils each has (svc/dvc) so post the model numbers and we can help you decide which is better

the subs are the 12w 1v2's

as far as the amp goes im not so sure about that, sorry about that but i gotta dig up the papers on that

Connect 2 speakers to one channel and 2 speakers to the other channel.  Each channel will see a 2 ohm load.  The following diagram is showing the 2 speakes wired to one channel of the amp.  You will have to do this twice.

The 4 woofers wired for a 4 ohm mono load will yield the same exact amount of power as the following.  It is just easier to wire 2 ohms per channel.

Option 1 (parallel) = 2 ohm load Speakers wired in parallel Recommended Amplifier: Stable at 2 or 1 ohm mono

thanks a lot guys this really helps. and to wire two subs into one channel should i put  the leads of both subs into the channel( either it be positive or negative), like put them both in seperately or should i twist the wires together?

sorry if im confusing anyone im just not so sure how to word this

thanks again

It makes no difference as to whether you twist them together or put them in separately. Ideally with a couple of wires going in I would put them in separately, one on either side of the screw. Even better is to get a proper spade terminal and crimp or solder it onto the wire and put it under the screw. This also makes for a cleaner install.

I also agree about the post made about clipping an amplifier. It makes no difference to the amp as far as what is connected to it. It is all about the signal getting into the amp that is important. Feed the amp distortion, the speakers will play distortion until they die a horrible smelly smoky death. While kbirtch is on the right path, he is not quite at the end of it.

kbirtch, don't go away, come back and learn. Ask questions, as many as you need. Nobody here is going to judge you, especially the senior industry guys on this forum. Learn and then you are passing along the correct information and not improper information that another person in the future may rely on. Post up a help me understand thread if you want, I would most certainly respond to it when I have the time and I know for sure that the other people here on the site would as well. There is always something to be learned.
