RF HX2 and MTX 1004

I've got 2 Rockford HX2 (2212)     ... 12", dual voice coil    4ohms,  500rms 1000peak... and I'm lookin for an amp..

would an MTX Thunder 1004    (1000 watts, 4 ch  ... 500x2 bridged @ 4ohms ...)    do the subs justice? 

That amp will put out 500 watts RMS x 2 channels @ 4 ohms, not 2 (it won't run at 2 ohms bridged).  So you'd need two DVC subs with 2-ohm voice coils to be able to get 500 watts to each sub.  With the 4-ohm voice coil HX2s that you have, you'll only be getting 360 watts RMS per sub.  It would work, but there are better options.

There are two ways to hook up 2 of your subs for a single ouput, and you can end up with either a 1-ohm load or a 4-ohm load.  This applies to a 4-channel amp and a 2-channel amp because in both instances you'd more than likely be bridging both amps.

One amp to consider is the JBL BP1200.1.  You can find them on ebay for half the cost of those MTX amps and it puts out 1200 watts RMS @1 or 2 ohms.  Since it's a 1-ohm stable amp you could wire up each sub's voice coils in parallel, and then both subs together in parallel, and you'd end up with a single 1-ohm speaker load.  1200 watts RMS is more than the total RMS rating of 2 of your subs but that doesn't mean you couldn't push the subs hard and get good sound out of them.

If you're lookin at just MTX gear, think about the Thunder942 two-channel amp.  At 4 ohms bridged it will put out 940 watts RMS x1 channel.  Also it can run a 2-ohm stereo load and put out 470 watts RMS x 2 channels.  So either way you wired it up, the total amount of power going to each sub will be the same.

I 2nd the JBL 1200.1 you wont find a better amp for the price.

Great! Thanks :-)

..and i found the JBL on eBay for 245 + s/h... and then I found the MTX (942) on eBay for 345 + s/h!

and i always wanted a JBL amp but I had thought they were real expensive. .

ok I've got just another question ...

and BTW I'm new to this..

since that JBL amp is a mono sub amp does that mean I'm going to have to bridge my subs together instead of bridging the amp?

Well you don't really "bridge" the subs or the amp;  you will be hooking up your subs in parallel, amd each sub's voice coils will be hooked up together in parallel.  Here's a diagram of what it should look like:

ok! thanks a lot! you really know your stuff!
