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?

****, i was one minute late on that post...

lol new amp ftw

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.

If i wanted bullshit, i would of asked. I'm just wondering if anyone has used two amps into a svc speaker before.

sob, after getting it all hooked up, the newer amp's stupid protection light came on, and it was only getting power from my older amp, lame new amps...

yer a dumbass

 

[Hydrastas 10+ year member]

Instead of just being a ***, how about explaining why the protection light came on?

They've tried, and you ignored them. The protection light came on because you wired everything wrong. You can't bridge all four channels of a four channel amp to a single coil speaker. It is not possible. I don't care what you think you have done, you didn't. It is actually amazing that it didn't go *poof* as soon as you turned it on if you did wire all four channels together. If you were only running on set of channels to the sub, then you were only getting the power of those two channels. Just because you didn't hook up the other two channels doesn't meant that the power from them will magically transition to the pair of channels that you have wired. It doesn't work that way. You had both subs wired to a single pair of channels and it wasn't loud enough, probably because the amp was current limiting because you had it wired to too low of an impedance. If you would have listened to what you were told above, you would have run one sub off each pair of channels and realized that that was going to get you the most power from that amp and sub combo and been content with that, but instead you had to insist like a little punk that you knew more than the people you were asking advice from. If you knew everything to begin with, why did you bother the rest of us?

No, the protection light came on to the newer amp when i tried wiring both amps up to the svc sub. It wasn't until trial and error that I realized that the protection light came on simply because i had wired an extra remote wire from one amp to the other amps remote wire, and the new amp didn't like it. I'm quite confident that when i bridged the four channel amp to one sub, that the sub's cone moved much greator than it did when only bridged from two channels, i'd say that the sub was getting at least %60 more watts. I didn't know everything to begin with, after hearing nothing but bullshit, i decided the only way was trial and error...
