Best way to wire Profile CL1200 to a Dual 4ohm 12'' L7

[klepto 10+ year member]

Just like the title says, whats the best way to wire this amp to this sub.

The amp will run:

300 watts RMS x 2 at 4 ohms

450 watts RMS x 2 at 2 ohms

900 watts RMS x 1 at 4 ohms in bridged mode

The sub is in a 1.5 cu^3 sealed box that use to fit in my wrangler. Im gonna put it in the back of my hatchback for now till i get a new set-up.

Hmm...using a 2-channel amp for a DVC 4 Ohm driver isn't the best way to go about it...

You really need a DVC 2 Ohm sub or a mono amp for the best/easiest way of doing this, sadly.

But the best way to go about using what you have is to wire the amp in bridged mode and then wire the sub's coils in series like so:

Be mindful, though, that showing the amp an 8 Ohm load will result in the amp outputting approximately half of its 4 Ohm wattage rating, or about 450 watts in this case.

Would that be 450 watts per channel or 450 watts going to the sub totat. If that was the case, to get more watts out of the amp, could i wire it in a straight series?

For example just have 2 sets of speaker cable, 2 negatives running to 2 negatives on the sub, and 2 positives running 2 positives. This way would i be getting 300 watts per channel, and 600 to the sub total?

Am i totally *** backwards here?

450w total going to the sub in my wiring method which, after having a look at the specs for that amp, I cannot see a way of getting any more power to that sub using that amp.

To tell you the truth I'm not entirely clear on what you're meaning here.Negatives and positives originating where before they attach to the sub?

Sorry if i didnt make myself clear. The amp had 4 outputs for speaker wire, 2 negatives and 2 postitives. Its seperated by left and right. My sub is dual 4 ohm, so it has 2 inputs, or essentially 2 negatives and 2 positives. I was talking about running straight wiring from the amp to the sub, or the negative right on the amp to the negative on one of the coils on the sub, and the positive on the amp to the other positive on the sub. I would do this for the other 2 inputs on the amp to the other coil of the sub.

If wiried like this, would the amp be putting out 300 watts per channel, thus giving my amp 300 watts per coil and x2 thats 600 watts total. Does that make any sense or is my head completley up my own ***?

Okay - I'm with you now. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Yes, this is theoretically possible but not particularly the easiest task to accomplish. The problem driving multiple voice coils with their own dedicated amp channel is getting the gains matched together. If you don't have pretty much the exact same output coming out of both channels then the voice coils, as a result from getting unmatched signals input to them, won't move in tandem. Over time (sometimes shorter, sometimes longer depending on how far off the settings are from one another) this will eventually lead to driver failure. //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif That always makes for an unhappy audio owner in my experience...

Was the sub acquired from a source that might exchange it for a DVC 2 Ohm model instead by any chance? That would greatly simplify things using that particular amp if so.

Well this is just a temporary set up untill i can choose what sub i really want...thinking of the RE SX...//content.invisioncic.com/y282845/emoticons/yumyum.gif.0556df42231b304b9c995aefd13928a8.gif . Ill just run it like you previously said for now and when it comes to selling this equiptment, i can just sell them seperatly i suppose. Are there any negative side effects for the driver running it this far below reccomended RMS?

no, just dont let the amp clip

 

[klepto 10+ year member]

no, just dont let the amp clip

What does that mean?
