How to change impedance

Ok, you're going to want to bridge the amp...

So, channel 1&2... bridge. Take the positive and negative from one subwoofer and wire them up to the amp according the the "bridged" configuration noted on the terminals.

Do the same for the second woofer, except on channel 3&4...

what does lower impedances do to the system?
I can try to explain it, but it would be a little to much for you. Basically lower imp allows more stuff to flow. more stuff usually = more power than you had. BUT, you have to have the amp to support it, and the speakers to set it up.

Are you in HS? If you are, you could go and ask one of your physics/science teachers, and I'm sure they could help you. If not, then ask to borrow a physics I book, and then look for the electicity chapter. Will tell you everything about it you need to know.

 
I already took physics, but we never got to the electricity chapters lol. I hooked up both the subs at a 2 ohm load, bridging just two of the channels, and it sounded as if i had all four channels bridged. So a lower impedance with lower wattages is equal to higher wattages with a higher impedance? It seemed as if the speakers were more in sync than otherwise though. My amp is old and i have no idea what ohm loads it supports though, after about 5 minutes with them at 2 ohms, the amp was able to fry eggs. That normally takes 30-45 minutes to get that hot with all four channels bridged at 4 ohms. I'm still curious about being able to bridge all four channels at a two ohm load with 2 svc speakers though, that would allow my speakers to get the power they need to run at rms. So if i were to hook the positive and negatives of the speakers together, then splice two new wires from each one, and bridged all four channels, would that be of any use? Or would the speakers just sound messed up, from getting the output from four different channels?

 
Instead of buying a new amp, i've realized that just having one of the 15's bridged into all four channels and facing the rear of the trunk it is best. It tops both 15's squished next to each other running at 2 ohms with the four channels.

 
I've decided that the four channels are not enough, so i was wondering if it's possible to use two amps to drive one speaker? Would they have to be the same kind of amp if i did? Could I use one amp to drive one channel, persay have one amp for the left channel running at 250 watts, and for the left channel have an amp running it at 300 watts? would i need to splice four wires from the speakers two wires? It is just a svc speaker... So if i were to run two positive wires from the positive and the same for the negative and then hook the four wires from the one speaker into the two different amplifiers as if it were two different speakers, would It be ok? Should I set the gain on the 300 watt amplifier down to 250 watts, so that the channels were even in wattage?

 
No man, its a hell of alot louder if you run 1500 rms to the left side, and 200rms to the right. //content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif

But in all reality, please dont blow up your stuff that you have. Read around a little more or go let someone install it. Go to http://www.the12volt.com and go the sub wiring configurations.
