Ohm load of X amount of speakers

Coils in series add:

R(total) = R + R + . . . .

Coils in parallel add as inverse:

1/R(total) = 1/R + 1/R + . . . .

Draw it out on paper. You can have any combination of series parallel you want as long as it is SYMMETRICAL (don't put 3 coils in series paralleled with 2 coils in series, etc.)

Example:

6 subs with dual 2 ohm voice coils (12 coils total):

You can have 12 coils in series = 24 ohms

(6 coils in series) paralleled with (6 coils in series) = 6 ohms

(4 coils in series) paralleled with (4 coils in series) paralleled with (4 coils in series) = 2.67 ohms

(3 coils in series) paralleled with (3 coils in series) paralleled with (3 coils in series) paralleled with (3 coils in series) = 1.5 ohms

etc.

Just use the nominal impedance - D1, D2, D4

0.7 and 1.4 are the DCR and should not be used to calculate your impedance.

Current system:

1997 Blazer - (4) Customer Fi NEO subs with (8) American Bass Elite 2800.1s

Previous systems:

2000 Suburban - (4) BTL 15's and (4) IA 40.1's = 157.7 dB at 37 Hz.

1992 Astro Van - (6) BTL 15's and (6) IA 40.1's = 159.7 dB at 43 Hz.

HUH???? lol I'm to drink to think now. ill re in mornin :cheers:

Seems like sum good info thaugh

12- DC Audio m2Lvl3 12's1- Hertz HSK3 way2- DC5K's2- ZX350.42- Stinger SP1500D batteries in rear3- runs of 1/0ga. to the rearTeam DC Audiodc-banner.jpgdcsoundlab.com

Quality is all in how you take pictures ;) I have plenty of projects that look WAY better on camera then in person :D

crazy to fit so many in so little. Reminds me of some of the porns I've seen?

The answer is.....negative 2 ohms!

2006 Cadillac Escalade

2/3 drop on 28" wheels

Two RE SX 18" subs

RF T2500-1bdCP amp, 3531watts on birthsheet

Custom carbon fiber sub box

EVERYTHING else is stock, for now

149.4 @ 37hz, Termlab, dash, open window on two AQ3 18s all stock electrical, wired to .25 ohm on a RF T2500

148.8 @ 36hz, Termlab, dash, open window on one AQ3 18 all stock electrical, wired to .5 ohm on a RF T2500

147.8 @ 38hz, Termlab, legal, sealed on two RE SX 18s

146.4 @ 36hz, Termlab, legal, sealed on one RE SX 18
