can somebody clear this up for me?? what is better a 4ohm 2 ohm or 1 ohm, or should you go as low as the amp is satble?? i thought less resistance means more power?? also if you bridge an amp you go from 4 down to 2 right?? does them amp load have to match the sub load?? and what happens if it doesn't??

 

There is no better when it comes to 4 ohm or 2 ohm or 1 ohm. What is important is that you match your subs to the amp. You are right about less resistance = more power, but only to a point that the amp can handle. See the examples below.

If your amp has 2 channels at 4 ohms- You can connect 1 sub to each channel as long as each sub is 4 ohms or greater. DO NOT connect a 2 ohm sub to this example, you WILL burn out your amp.

If the above amp is bridgeable, you will have 1 channel at 2 ohms- You can connect 1 sub at 2 ohms, or 2 subs at 4 ohms wired in parallel. Do not connect a 1 ohm sub to this example, you WILL burn out your amp.

OHMS LAW: Wire equal resistance speakers in series = Resistance doubles ex: (2) 4 ohm speakers wired in series present an 8 ohm load to the amp.

Wire equal resistance speakers in parallel = Resistance is cut in half ex: (2) 4 ohm speakers wired in parallel present a 2 ohm load to the amp.

As long as you make sure that the resistance of the speakers is equal to or greater than what the amp is rated at, you will not have any problems. Also, to get the maximum power your amp is capable of, match the resistance of the speaker to the rating of the amp.

If you want, you can e-mail what equipment you have, with all the specs, and I can let you know what all the different options you have available to you. Good luck.

Yes, less ohms=more power, but you have to make sure the amp/sub combination can take it. And less ohms takes more power for the amp.

It depends on you sub/amp combination, SVC or DVC

If its not done right, it will just sound bad, or it might blow up

Subs are 2 10" dvc clarion pxw's 600W max sorry don't know rms yet
amp is soley for subs should i seperate subs in a single box with a baffle?? or leave it?

any suggestions is appreciated

 

I need to know what the impedance of your subs are.

As for the RMS of the subs, don't worry about that. If they are 600W max, their RMS rating is going to be roughly 300W.

If I had to guess, those subs are probably going to be rated at 2 ohms when you have the voice coils wired in parallel. So, I would recommend running 1 sub per channel, with the voice coils wired in parallel. Based on the power ratings of the subs and the amp, you'll be safe with this setup, and have more bass then you'll know what to do with . Just don't bridge that amp into those subs, you'll blow the subs.

Your last question about the box. When you say should you seperate them with a baffle or leave it, what do you mean? What are they in now? If the subs came mounted in a box, I would leave it as is.

Good luck.

 

oh ya they are dvc 4ohm per coils subs, no they will be purchased seperatly and put in to my old box that has 2 seperate chambers. It would be easier for me to have the middle seperation plate removed as one side of the box has a big notch out of it, making the volumes different on each side. i will be adding an extension on the front of the box to create more volume, that these subs require. I was thinking that if i bridged the amp and ran 1 ohm through the 2 subs wired in parralel i wouldn't have to worry about the subs firing at slightly different times or having one gain slightly diff, than the other channel. But if you say this will blow the subs i will not do this

That makes me wonder there are 2 gain ***** right?? if i bridge which gain will be the working one???

Also it says typical 2 ohm stereo?? will there not be even more power in mono?

And last of all i will run a 4ga. wire from the battery in place of my old 8ga.
can i put a distribution block before the 2 amps and run 4ga. from there to the 1000w and a piece of 8ga. to the 400?? or should i run both wires right from the battery? roughly 12-15ft long from battery to amps.

Thanks again

 

Don't run it bridged. The bridged power level exceeds the max power of your subs by 400W, they will blow. The amp should be labeled to tell you which gain **** will be working if you bridged. Again, don't bridge.

Yes there will be more power in mono, that is the bridged setting. Stay in stereo to avoid fried subs.

A single 4ga running from the battery to a distribution block will be fine. No need to run 2 4ga wires from the battery. DON'T FORGET to fuse that 4ga wire about a foot from the battery!!!!

I'll be away from the computer until tomorrow night, so if you have any questions I'm sure someone else here will be able to help you in the meantime.
