depends on how they are attached to your current charging system. If wired in series then yes. I have had to make a self contained jump start for a boat we did because the stereo was so large in it, it would drain the main battery if they were floating on the lake listening to music for a few hours without starting the engine.

can someone give me a clear diagram for two 4 ohm DVC subs getting a 1 ohm load on a mono amplifier please...a clear diagram, i dont understand the ones at 12volt and rockford fosgate, i understand crutchfields but they dint have how to get a 1 ohm load with 2 4-ohm DVC subs.;

here you go

Connecting the voice coils of each driver in parallel (+ to +, - to -) and the drivers themselves in parallel (+ to +, etc.) will result in the following impedances:
Dual-6 Ohm Subwoofers: 1.5 Ohms
Dual-4 Ohm Subwoofers: 1 Ohm
Dual-2 Ohm Subwoofers: 0.5 Ohm
Dual-1.5 Ohm Subwoofer: 0.38 Ohms

thanks, im getting this amp http://www.sonicelectronix.com/item_...KAC-9104D.html

What does it mean wen it says "1 ohm: >900 watts x 1 chan." does that mean more than 900watts or less?

**carsey** · 06-08-2009, 03:20 PM

900Watts RMS at 1ohm resistance with 1 channel.

NOt sure if you will get more....but RMS figures should be precise

rvpr4 · 06-08-2009, 06:45 PM

oh,
i knew i was gunna get 900 watts RMS at 2ohm and 1 ohm but wen it said 900 watts RMS @ 1 ohm it had a ">" sign before it said 900 watts, it didnt say that for 2 ohm, so thats why i was wondering if ill get more or less than 900 watts AT 1 ohm.

lcurle · 06-09-2009, 08:07 AM

> = More then, < = Less then, They have not confirmed their numbers that is why it is just a ">900" That mean the amp is not CEA approved.

rvpr4 · 06-09-2009, 11:14 AM

but it says CEA 2006 compliant amplfier...i thought kenwood amps were CEA approved...
well so i guess its better for a 1 ohm load than 2 ohm load since > means more than 900watts..

lcurle · 06-09-2009, 02:17 PM

it is set up for a 1ohm load more so then a 2ohm load, if it says CEA 2006 compliant then your good to go.

rvpr4 · 06-09-2009, 03:23 PM

thanks for yur help:) ill set it up to 1 ohm load.

rvpr4 · 06-10-2009, 05:21 PM

Can someone give me there opinion on this amplifier? http://www.sonicelectronix.com/item_...on+X1200M.html

It's a Kenwood eXcelon amp, it's 1200watts RMS@ 2 ohm 2400 watts peak. It says CEA-2006 compliant amplifier so it shud be good, i just want someone elses opinion.

thanks.

lcurle · 06-11-2009, 06:36 AM

it is a kenwood, I have had some bad luck in the past with them, unsure of their current amplifiers though...I need to be because I sell them....now I have to go look.

**Raylo** · 06-11-2009, 06:02 PM

Wow, all this concern over alternator, capacitor,wire, and battery size and capacity. What about the young man's internal organs after 2000 watts of 5 hz bass go through them? ;-) You kids... Good luck!! I hope it all works out!

lcurle · 06-11-2009, 07:03 PM

2000 it peanuts when talking SPL (Sound Pressure Level). Double beating your heart...making your eyes fall out, now thats power!!

rvpr4 · 06-12-2009, 05:33 AM

lol im not even going for 2000 rms anymore, im just getting 1000 rms, but ill still have to upgrade the big 3 cuz the amplifier is fused at 150A! thats like 1500 watts right? its a fosgate btw:P

**carsey** · 06-12-2009, 02:28 PM

I read in my vibe amps instruction manual that a amplifier might potentally pull the fused amp load. But the more than likely run at a 1/3 of their fused load.

Quote:

An aftermarket audio amplifier will place an additional load on the vehicles charging system, most
modern vehicles have sufficient capacity in the charging system as not all the electrical
components of the vehicle will be switched on at once. Check the fuse rating of the amplifier and
use this as the peak current requirement, generally the continuous current draw will be a third of
the peak current, in other words an amplifier fused at 30 amps will have a continuous current
draw of 10 amps when playing music, however it may peak at 30 amps on occasions. Please
check with the manufacturer as to whether your vehicle can cope with the additional load of your
amplifier, in some instances it may be necessary to upgrade the alternator and battery or risk
damage to the vehicles electrical system.

most amplifiers have a "warming" on them about charging systems.

rvpr4 · 06-16-2009, 07:21 PM

anybody know if lightning audio amps are good? im looking at a strike series 1000 watts RMS @1 ohm...it says CEA-2006 Compliant Amplifier....but does anyone have experience with them?
