Good lord Go with the lowest ohm, Im not sure how ur wiring it but the 1ohm amp will work better than the 4ohm setup If i under stood u right. Ugh I hope u know what your doing

What ohms are the subs each? And are they dual voice coil??

4 ohms and single

This wiring calculator I found let me type in 12--12in 4ohm subs, and in a Parallel load

you should get 1.66ohm thats right a 1ohm...So if that it true I would find one amp thats 1ohm

stable and wire it like that. Check the set up with a ohm meter before you wire it to your amp.

Here is the link i used

That calc is way off... you're gunna need to wire some in series and some in parallel to achieve the resistance you need...

I'd just go with 3 1kw amps, 1 ohm each, keep it simple, if u have the space to mount all those amps at least

or you could go with like an HK4000D, which does like 2k @ 4 ohm, 4k @ 2 ohm, so you should be able to get around 3k @ 3 ohm by wiring all of them down to 1 ohm per section and then the 3 sections in series

After more consideration, this is definitely what I would do. Make sure you have enough battery power to back it up, those amps are current hogs

you should be able to find one for around 400 shipped too

I would have to agree 3 amps would be best. I use those wiring cal to get an idea, But I ALL WAYS CHECK THE OHM'S with a meter before wiring it to

the amp, And lets no forget to check the POLARITY too

if you dont already have the subs just go with like

4 - 12's that are better subs

and

1 big amp

if you are going to be spending a good amount of money you may as well get something better quality.

if its ported then those subs will not handle 250rms each. more like 125 maybe 150.

ok 12 subs..... 4ohms each

break it up into 4 sets of 3

3 4ohm in parrellel = 1.33ohms

so now you have 4 sets of 1.33ohms, break that into 2 sets of 2

2 1.33ohms in series is 2.66ohms

so now you have 2 sets of 6 subs at 2.66, wire those 2 sets in parrallel... final load 1.33ohms

wire it like that, hook it up to a bxi2608 should make for between 175-200w each

which in all honesty doesnt not sound like fun AT ALL, im thinking 4 sdc2.5's on a zx2500 sounds alot better honestly

 

[oldschool4me 10+ year member]

alot of time and work spent on $10 subs.
