Ok, not sure if everyone understands, for the last time i realise about the benefits of wiring options, so stop explaining that, i know!! Ok here's an example. If i had a 10cm long wire wrapped into one single loop vs a 50cm long wire wrapped into 10 loops, which one would produce the bigger...

Obviously you don't know a lot about electronics and/or physics. My question is a lower resistance can be achieved by: - More coils (longer wire) - Thinner wire (Lower cross sectional area impedes current) But if more coils are utilised, the magnetic flux is increased, which i believe would...

what you laughing at? It's a completely valid question

I have an interesting question. If you were to get two identical subs but with different voice coil arrangements (one with 4 ohm DVC and one with 2 ohm DVC) would there be any noticeable sound quality differences? Would the 4 ohm sub have more coils to achieve a higher resistance whist providing...

What about something like this: http://cgi.ebay.com.au/2-X-DUAL-FAN-ANODIZED-ALUMINIUM-HDD-COOLER-KITS-Blue_W0QQitemZ8723221948QQcategoryZ70876QQrdZ1QQcmdZViewItem I could attach it to the amp with thermal adhesive (Transfers heat, but kinda like super glue) what do you reckon of this idea?

Haha sounds humorous, subs on a cart. anyways have you thought about the electrical system? Surely you wouldn't have the power to run something half decent

P=VI V=IR P=I^2*R When voltage is doubled in the case of bridging, the following happens P=2VI Therefore P=2V^2*R For example if voltage was 10v in stereo and 20v bridged, then @ 4ohms In bridged- (20)^2*4= 1600 watts In stereo- (10)^2*4= 400 watts So bridging has the effect of...

sorry i was confusing, if you want to be confused more then the technical reason is: In bridged mode, the voltage is effectively doubled, hence you get double the power, at this point running at 4 ohms mono takes as much power as 2 ohm stereo. It's hard to explain but it comes down to ohms law...

Hey guys, my 4 channel amp is waiting to have 2 of it's channels bridged to run a sub, pics at: http://home.iprimus.com.au/m_baldan/ With two channels bridged it will put out 380wrms @ 14.4v @ 4 ohms. I have a few problems, however. Firstly what is the best size for rock music. I would love...

In mono mode, both channels see half the load, i.e. in stereo mode 2 ohms is the equivalent of having 4 ohms (as there is 2 ohms present on each channel) in mono mode, 2 ohms in mono would mean your amp is stable at 1 ohm in stereo

Yer, if you want a ballpark figure, assume your amp is 70% efficient, if you know the exact value then that is better. But at 2000wrms @ 70% efficiency your power draw is 2800w, i=p/v, therefore i=2800/14.4, or 194 amps!!!!!!! You're gonna need a serious alternator not to mention some serious...

Assuming your amp is 70% efficient, i don't know if this is a reasonable figure, but anyways. The current drawn will be: i=p/v where i is unknown p= 1560w (70% efficient) v= 14.4v (If this is the quoted voltage for 1200wrms) Therefore i= 108 amps You have a little bit of reserve to play...

Hi there, i don't know a terrible lot about amps but i know a whole heap about electronics. Can you make an amp stable at a lower impedance? Theoretically yes, but in practical terms no. The heart of an amp consists of mosfets, semiconductors that basically take a small input voltage and pass a...

thanks for all the input guys, i'll see how it goes. It will be interesting to see how much hotter it gets when i get a sub going. Are there any easy ways to cool amps? I was thinking of attaching a couple of computer fans on it, and running them off the relay which switches on with the remote...

Hey guys, i just turned 18 ang got my self a 1992 S13 Nissan silvia Q. As i have limited space to play with in the boot, i mounted the amp on it's side against the rear of the back seats, you can see the pics at: http://home.iprimus.com.au/m_baldan/ the amp puts out 100 wrms into 4 channels...
