Wiring subs to super low ohm's


Recommended Posts

Direct Current Resistance. It is just the resistance of the coil wire when DC is applied. It is the resistance seen if you were to connect a 9 volt battery to the coil.

Music is Alternating Current, not DC. DC would cause the cone to move in one direction and settle in one position based on the voltage applied. AC is why the cone moves in and out (in very simple terms - the positive and negative alternate on the coil terminals). AC impedance changes with frequency, so the coil is given a nominal, or average impedance rating.

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.

Here's the thing.... You are asking if it will be safe - eg reliable, not risky, no chance of failure. Here's the thing.. Wiring at 1/3 ohm will never be safe.

Can you get more power? Maybe. But at a higher risk of frying equipment. You need to decide of that's the risk you are willing to take. No one here can guarantee long term reliability running at .33 ohms.

If you are willing to accept losing an amp wiring that low, then by all means. Go for it. If you aren't, wire to a higher ohm load and get a larger amp that will do the power you need at that load.

people these days wiring amps so damn low, i honestly only do it for spl, for daily i don´t go lower than .5 ohms depending on the electrical, not the impedance rise!

I´m the SPL Gains topic creator!! wanna get louder?? check this: SPL Gains. Panamenian 2009 & 2010 & 2014 Bass Race 149.9 Champion!

2 15" subs and a 2K wired at 1 ohm, http://www.stevemeadedesigns.com/board/topic/167788-fecupe2001-2-15s-on-a-2k-video-on-page-3/

8 Massive 15" subs and small power, http://www.stevemeadedesigns.com/board/topic/179296-fecupe2001s-8-15s-4th-order-bandpass-wall/

have wired way down before on some great electrical, no issues whatsoever.

great electrical consist of

6 runs of 4/0

8 batteries

4 DC power 280 amp alternators

1 mechman AVBM charging at 15.2

ohm loads we run at on a consistant basis (nominal) on music

.17 .35

it also helps to have a good amp that if perhaps it goes into protect, that its able to come out of protect.
