kenwood 7201 amplifier

OK I have got a 2 channel 800watt max Kenwood 7201 amplifier. The specs are as follows.
Bridged RMS 460 watts x 1channel @ 4ohms
230 watts x 2channels @ 2ohms
150 watts x 2channels @ 4ohms
 
here are a few questions that I have about this they are as follows.
1- If connecting 2 svc speakers in the bridged format would the wattage be split between the 2. As far as I know yes just correct me If I am wrong.
2- Taking the same 2 svc speakers and wiring them into a 2 ohm load how would I wire them to the amps channels to make the amp give the 230 watts @ 2 ohms.

The only solution I have came up with for question #2 is this.
Wire both positve terminals together do the same with the negatives. You now have a 2 ohm load for the speakers. If this was a monoblock that would not be a problem but since the amp has 2 channels the 2 speakers would only be getting 230 watts. Now add to one of the positive terminals 2 wires one to each of the positives on the amp do that same with the negatives. Would this not still be a 2 ohm load with both speakers drawing current from both channels at 2 ohms at 230 watts a channel? Thus enabling the same amount of current of a bridged load at 4 ohms but since you cant wire svc subs into 4 ohm according to the wizard on here this would be the only logical way to get the max power out of it for 2 svc subs. If you understand it fully and know for a fact that I am completely wrong please just tell me so. If you need me to draw up a diagram I would be happy too.

Are the woofers 2-, 4- or 8-ohm drivers? Without knowing this information we can't answer your questions completely.

If they are 2- or 4-ohms, you are stuck with wiring them in stereo, and getting 150W or 230W per woofer.

If they are 8-ohms, then parallel wire them, as described, and bridge the amplifier to them. They will share the 460W.

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

Grrr apologies I thought I included everything....They are svc 4 ohm subs.

Read my post above. They are SVC 4-ohm woofers. You are stuck with running the amp in stereo. You will provide the woofers with 150W each. That's all you can do.

If you attempt to wire the system as you have diagrammed, if you are lucky the amp will turn off, if you are not lucky, it'll fry the amplifier.

I can make you this guarantee, though... You will hear no difference in output. Wire it in stereo. It's your only choice in your situation.

Thank you I figured that would be the outcome I was just thinking that it might produce the desired 2 ohm load. What if I wired a positive and negative wire to each sub and then bridged it on the amplifier. As described in the following diagram. I am sorry if I am making your head hurt and wasting your time I just have a lot of ideas that I have no idea on and would like some input on.

You cannot bridge that amplifier into 2-ohms. Bridging into 2-ohms is the VERY same load on the amplifier as running it at 1-ohm in stereo mode, and an unsafe load for the amp. I've already told you the only safe option you have with those two woofers - stereo mode, 4-ohms per channel, and 150 watts per woofer. DO NOT BRIDGE THAT AMP INTO 2-OHMS!

I am confused about this now. You said do not bridge it into 2 ohms but the amp is at 4ohms bridged. There is no need to yell either none of the options I have given are going to be used they are just simply Ideas on getting more wattage out of a given situation.

I wasn't yelling, I was simply stressing a point. You cannot use that amplifier in ANY bridged configuration with two 4-ohm woofers, and still use both woofers. If you parallel two 4-ohm woofers, that is 2-ohms. You have two 4-ohm woofers. What you drew, in both cases, is two 4-ohm woofers in parallel... 2-ohms. To use both woofers, you MUST run in stereo, and connect one woofer to each channel of the amplifier.

Thanks for the input guys just trying to figure out if I could get a little bit more wattage out of the setup. Looks like I cannot. Time for a new amp!

Why? The acoustic difference between 300 watts and 460 watts, using the same drivers, will be inaudible! From 300 watts, you have to go all the way to 600 watts to gain 3dB. 3dB is BARELY audible at all! Don't waste a perfectly good amplifier, dude! (Well, as "perfectly good" as any Kenwood can get... AFAIAC, they're CRAPTASTIC! ) Additionally, the amplifier will last longer, (because it's running COOLER!) with lower distortion, better damping and better efficiency.

Are you competing? If not, then keep the amp and woofers you've got, and just go about your days! If you were competing, I'd say look for more, in both departments, but if you aren't? It'll end up being a waste of time and a perfectly usable setup...

If you don't have the woofers yet, then you need to get either 2-ohm or 8-ohm SVC woofers, or 4-ohm DVC woofers.

If you get drivers with those rated impedances, than you can bridge the amplifier into a 4-ohm load, and get maximum power from the amplifier...
