Itīs me again guys!

Now, I want you to recommend me a good and not expensive amp for my subwoofer.
This is a HED-10 Cerwin Vega, with DVC.

Besides, I donīt want to be heared 3 blocks away, nor enter a competition.

Thanks and Salute!

well, as you hopefully know and understand, that is a dual 4ohm woofer that can handle 200W RMS and 500 peak. I'm not sure if you are on a budget or not but I would reccomend putting the full 200 watts into it just because CV is a fine woofer manufacturer and that sub will thrive on all 200 watts. Seeing as it is dual 4, i would find a 2 channel ampo and wire the voice coils in parralel to create a 2ohm load to the amp. You need to know that you want to hook the coils to the same channel which is "mono". Many 2 channel amps will say "2ohm stable" but then if you read the fine print, they are only 2ohm stable in stereo mode, not mono as i have described. If you want to make te job easier, find a nice 200W mono amp and that will make life that much easier. But to tell you the truth, its a little difficult to find a mono amp that puts out only 200W. And most of the 2 channels aren't cabable of a 2ohm load when bridged. This would have been so much easier if you had 2 woofers or at least a dual 2ohm but what can ya do. But i managed to find this Coustic amp coustic600db But it still isa little overpowering (300W at 2 ohms). This one is a little better: Hifonics brutus bx500D. I happen to be a fan of Hifonics but again, this one is 50 watts over the "reccomended" RMS for your woofer. I tend to think as long as you are careful, you might be able to get away with it. Just keeo the gain turned down, pay attention to distortion levels, and use a sealed enclosure. Hope this helped. Oh, I only used sound domain because they are well organized. The prices are high so I would look on ebay once you pick an amp.

Look for an amplifier that will output 400 watts at 4 ohms, but wire your sub in series for an 8 ohm impedance.  Use any type of amp for this load.  BTW, your last thread on this subject seemed to have gotten all the answers you should need to get you going...

A cheaper alternative is to just buy another $49 subwoofer just like the one you have, and together they'll make a 4 ohm load to connect to an amp.  You'll have a much easier time finding a cheap amp to drive them, and stay within the power range for the speakers.  You can get by with as little as 100 watts to each sub, so you can see what a wide range of RMS power output you can look for (200 to 400 watts @ 4 ohms).

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

and what will happen if I use the Sony Xplod amp that I have...

In the specs is: 1 Ch x 120W at 4 ohm (0.1% THD)

And connect the coils in series, to get 8 ohms load...

Will it work good?

Once you have those voice coils hooked up in series, like this, you can't hurt anything no matter how you hook it up.  Try it out, what's to lose?
