I just built my entire new trunk setup, Too-bad its still uncarpeted,and sorry no pics yet you'll like em when I post them I'm sure [img]smile.gif[/img] I still need to tweak some wiring.. So, thats what i need to know:

does anybody know how to wire 3 subs @ 4ohms into one set of speakerwires. (1 + 1-) so I can bridge it to my amp.

It Was done right when i got them in the box, but then i took the subs out, and built all seperate boxes, and they arent all next to each other.

anybody have a diagram or can make a quick one for 3 subs and "just say" one "box connector"..

-thanks you stereo Freaks!!

What subs you got (i.e. 2-ohm/4-ohm, dual voice coils)? What amp?

I dont remember if they are 4ohm voice coils though.

I remember that when I did wire them up, it was fun. I might still have the wiring sheet I was sent at my parents house back in the burg. I'll be out there tomorrow or the day after.

3 speakers at 4ohms a peice gives you 1.333 ohms in series. (1/[(1/4)+(1/4)+(1/4)]) You need another sub to get 1 ohm. Or get rid of one sub and you get 2ohms. If they are dual voice then that will be a different story.

The subs, when I bought them and wired them it represented a 4ohm load to the amp according to the wiring sheet.


Yes, they are DVC [img]smile.gif[/img]

Three 4-ohm speakers in parallel give you a 1.3 load. Put them in series and you have a 12-ohm load. Two in series with each other and in parallel with a third would be what, 6 ohms?

don't forget guy's that If you bridge you amp it will only see half of the impedance for instance if you parallel 2 8ohm woofer's you would get 4 ohms of resistance put that to the amp bridged and the amp would see 2 ohms so Zbassman has the best route

The final that the amp would see would be 3ohms IF your amp is only rated at 2ohms bridged this is your safest bet

Sorry, i meant parallel and 2 in series and 1 in parallel give 2.66 Ohms not 6. A good way to figure a rough estimate is that the final ohms will always be lower then the smallest ohm load when involving parallel (so 8 & 4 thus less then 4).

The only 3 speaker setup I know of are the JL 6 ohm series. You still need to get rid of or add a speaker. Most amps do not like the strange ohm loads and can run hot.

Yes they are 4ohm Dual Voice coils (old fosgate 10"s) with a kenwood 600W amp. ( i know, not the greatest for sound quality )
LOL greg, i took the subs out, to measure the box for Cu-area, and to measure the depth for the box, and So i totaly got confused with the wires in the box so i kinda confused myself pretty bad... [img]3.gif[/img]


you guys REALLY have me confused, so your saying go 2 ohm even though there 4ohm subs?

I wish i never undid the wiring, it sounded badass before,
