I'm in the middle of attempting an SQ build and I'm wanting to replace my current sub amp (kenwood exellon 401M 600RMS @ 2ohm) with something a little more updated.

These are the subs I'm running

http://www.partsexpress.com/pe/showdetl.cfm?&Partnumber=295-464

Also the enclosure that is being built is 3.3 cuft sealed per sub w/ seperate chambers.

I would like something in the 800RMS range and in the $300-$400 range (of course the cheaper the better lol!)

Thanks for the input!

I'm sure you can find a used PDX1.1000 for a good price somewhere. Unless you settle for a 1.600.

I have two of these woofers also.  I believe your box is too large.  According to Rich Taylor with Dayton Subs,1.2 cu ft for the Reference 12" with an F3 of approx 44Hz.Hope this helps!Best Regards,Rich Taylor.

I put my two in a cabinet with a total volume of 2.4 and they rock.  Very strong and great sq.  I have a cheap Visonik V1800 amp on them and they still sound great.  The amp is about 500 watts so the speakers could handle much more power.  The two are in a Ford Escape sport utility vehicle.  Back in the late 80's when I competed in stereo contests I posted spl's as high as 148 and I would say from memory that this setup is very close to that or even that high.  This is my guess since I don't have a meter any longer.

Just thought I would pass that info along.  That box volume sounds really big for speakers with the Thiele parameters to me.

Good luck.

Daniel

Oh by the way, I was thinking about buying a PG V8001 from Parts Express as an upgrade to the Visonik.  Right now the amp is around $300.

I have a very old PG MS250 and I am very pleased with it.

I also like the PDX1.1000 but the price is out of my reach right now.

Well, then keep saving your money, theirs no point buying something that wont make you 100% satisfied, face it, you'll get the PG amp, then a few weeks later you'll be wondering what it would be like   to own the PDX, next thing you know your going to be selling the PG so you get get the PDX.

Forget my suggestions to make your box smaller.  I found another thread where a much more knoweldagle guy told you to use a 3.3 cu ft box.  I am now trying to figure out how to make a bigger box for my Escape and still be able to carry dog food and groceries.

The Daytons are awesome speakers though.  I love mine even if they are in a small box.  sq sub amp suggestions -- posted image.

ya, haemphyst has been helping me with everything. He's told me what toys to buy and the crossover points and all sorts of fun stuff like that. I thought 3.3cuft was way massive for those subs too (dave asked me how much room I was willing to give up then he figured up what would work well for my application), but I don't know just a whole lot when it comes to SQ, and He does, So I listen to him. Thanks for your replies though! every bit helps!

I'm going with the PDX1.1000, PDX2.150, and a PDX4.100
