Hello everyone,
I finally got some money over christmas to buy a new amp to run my subwoofers, I unfortuately blew the last amp up and have been running pretty much bassless since.
Background:
Vehicle: Jeep Wrangler
Set-up: 2 12" Eclipse SW6200 series subwoofers with an RMS of 350W and Max Power at 1000W (factory website) in a 3.5 cubic foot ported box. The speakers are rated at 4 ohms for each of the two voice coils. The box is mounted to a custom built mount attached in the rear of my jeep.
I have the correct wiring (4 gauge) and fuses (a large glass one) for the wiring, and was looking to upgrade my amplifier to a fairly good quality amp. I have a good budget and am able to spend up to $500 on the amp. I am looking for some good sounds, and good efficiency out of my amp. What would be some good amps to buy, or is there a particularly excellent amp for my purposes? I have been in Montana for the last week and will be for another, plan on purchasing the amp within the next month.
I would appreciate any help that you can offer and any suggestions that also might be offered.
Merry Christmas and have a Happy New Year!

Merry Christmas to you as well...
OK, dual Eclipse subs, 350 RMS, 4+4 DVC's are what you have and need an amp that can deliver a solid 600-700 watts RMS power and has an Infrasonic filter as well.
There are 3 main options:
1. A 1 ohm stable Class D amp (Most efficent use of power)
2. A matched pair of modest Class D amps (2 ohms stable, 1 amp per sub)
3. A 2 channel amp that can be bridged to deliver desired wattage (A real power hog)
Items #1 & 2 are the most practical approach. Class D amps are preferred for subs as they are typically very reliable, 80% efficient with power demand and often very affordable too. A 1 ohm stable amp is harder to find and typically more expensive as they need more power transistors and better heat dissapation to handle 1 ohm loads well.
HiFonics is well known for solid amps that are 1 ohm rated. The Titan TXi 1007 (900-Watt x 1 RMS @ 1-Ohm) would do the trick. Yes, it's a little strong and careful setup steps will be needed here and it has a subsonic/infrasonic filter too. Now, let's see what they cost?

Yes!!! $250 + S/H is a very good price for an amp of this quality, features and power. It even comes with a remote bass control for dash mounts. (That's a real plus when used sparingly)
Specs:
700 watts RMS x 1 channels into 2 Ohms
900 watts RMS x 1 channel into 1 Ohm
Class D Design
Frequency Response 1Hz - 400 Hz (-3dB)
Damping >250
Signal to Noise Ratio >95 dB
THD + Noise 0.1%
Channel Separation > 70 dB
Variable Input Level 0.2V - 9V (RCA/Unbalanced)
Variable Subsonic Filter 15 Hz - 35 Hz
Variable 24 dB/Octave Low Pass Filter (35 Hz - 250 Hz)
Variable Bass EQ (+18 dB @ 45 Hz)
Dash Mountable Bass Control Included
Gold 4 Guage Power and Ground Connections
US $249.95
OK, this fits the budget with cash left in your wallet for other things later. There's not much detail on this amp off Google, but from what I see, this is a very good deal for a very strong and generally reliable amp. It has all the basic and advanced features most would need and from what I can tell, it has enough RCA preouts for future upgrades to a 4 channel amp as well.
Note: This amp is strong and likely to challenge the stock electrical system in any stock import. Am estimating current draw at close to 65 amperes of current at 700 watts output. That often means electrical upgrades under the hood later as well. That's where the extra cash will come in handy later. (you're gonna need it with this amp)

Swez,
First of all thanx for the quick reply. I apreciate the assistance and explanation. I just read over the webpage for the titan amp. But to make sure that I understand, this suggestion is option 1
[1. A 1 ohm stable Class D amp (Most efficent use of power)]
is what you are telling me that I should do? That this Titan TXi 1007 this is able to run both of the two subwoofers in parallel? Or is there another way to run this?
Keep in mind I am not the best electronics kinda guy, I have a basic knowledge of electronics from high school, and that is about it.
Also, I looked on the Hifonics website, I can't find any of the Titan TXi 1000 series... Maybe I am looking in the wrong place, is there anywhere else other than that website to find the 1007?
Thanx again!

Swez,
Ok, I am an idiot, I mis-read the page, found the 1007 buried in the fine print.

Yes, both subs wired in full parallel nets 1 ohm and this amp can handle that plus it will deliver all the power your subs can handle and a little more for transient shots of heavy bass notes too. Door #1 is the best choice here.
Also, you'll want to buy an inexpensive Digital Multimeter for setting this amp up properly. A usable one is about 15-20 bucks and can be purchased at Radio Shack, Wal Mart or most good car parts stores. This one has all the features you'll need:
