15 subwoofers on 2 chanel amp.

Hah, I have my flame suit on currently so flame away.. :)

I have a 96 ford aspire in which i use as a winter beater up here in Minnesota. I have alot of spare time on my hands currently, and some extra cash laying around.

I fiberglassing up 15 10" subwoofers in the back (rear seat removed of course). Also 5 pairs of 6.5 coaxials.

Being that I am only using 2 amplifiers to do this, I am curious if any of you electrical geniuses out there can draw me up a couple wiring diagrams on how to wire all this stuff up properly.

one 2 channel amp - to - 15 single VC 4ohm subwoofers
one 4 channel amp - to - 5 (pair) 4 ohm 6.5" (2 pair in front, 3 in rear)

any help is greatly appreciated!

I hope your amp is .25 ohm stable.  Can I just ask one question, WHY??????????????  A really really really old Fosgate or a Orion might work but I think its a waste.

Im moving to MEXICO and Im not speaking spanish!

haha, told you I had my flame suit on.. Im not trying to produce max power out of these. But at least pull a descent amount of power through each one.

Is there any possible way this can be completed? or am I wasting my time, Couldn't I run say 14 instead (7 on each channel)..


The reason I am doing this is for some fiberglass practice, I've been working with it for 5 years now, but I am trying alot of new techniques on my personal vehicle instead of trying on customer cars.

Plus I can find anyone who has put this many subs in the back of an Aspire :)

Here ya go:

1: Wire 3 in series, 4 times. That's a 12 ohm "woofer".
2: Wire all 4 of them in parallel, for 3 ohms.
3: Bridge to the amplifer for 1.5 ohms per channel.

OR:

1: Wire 5 in series, 3 times. That's a 20 ohm "woofer".
2: Wire all three of them in parallel, for 6.666 ohms.
3: Bridge to the amplifer for 3.333 ohms per channel.

That's the best you'll be able to do with the woofers... In fact, they are your ONLY two options.

The 6.5's, again, depending on the amplifier, I'd only try to run two sets front, for 2 ohms, and two sets rear, again, for 2 ohms.

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

Couldn't you wire 5 subs in parallel three seperate times for .8 ohms each, then wire those 3 groups together in series for 2.9? Then you could use all 15.

It was already broken, but I made sure it could never be fixed again.

I appreciate your help!

is this a possibility also? or no?

Im available for all options!

I stand corrected... Two more options. Series-parallel, and/or parallel-series

Then he'd have to bridge the amplifer, still... And actually, it's a 2.4 ohm load.

2.4/2=1.2 ohm load per channel

Then, yes, you could use all 15, BUT the amplifer would have to be one ohm per channel stable. What amplifer is it?

If your amplifer is only 2 ohm stable, this is your only option.

Wow. I'm pretty sure I thought I could add .8+.8+.8? Cool. Time for bed.
