I am looking for a four-channel amp that puts out about 100x2 when bridged. Anyone have any suggestions on what brand and where to buy it off the net??

Four channel amps are not usually used to run subs... I've blown a couple in my time simply running them at perfectly reasonable loads.. I don't even know why this is.
A 50x2 amp that will bridge can give you 200x1.. Voila, now just wire the speakers right.

Hrm.....I would go with the other's advice on running 2 separate amps, or get one that can handle a 2 Ohm or lower mono load. However, if you're dead-set on a 4-channel to bridge down, then I'd start my querries with RF 200a4; MTX Blue Thunder, Road Thunder, and Thunder all make 25&37.5x4 (or some where around that #) amps; Infinity offers a 50x4, not sure how much longer though; USaccoustics offers a 65 & 85x4; Kenwood has 25, 35, and 50x4 or 120, 200, and 300x1 amps; Alpine, Eclipse, and PPI all offer great little beasties in the 25 - 50x4 range; and of course, you can go back to budget amps with audiobahn, crossfire, Profile *I'm gonna get flamed for that one *, etc. I think Orion offers a 50x4 in their XTR series and a 35x4 in their Cobalt series and a 25x4 in the HCCA series (if you're planning on running more speakers than Best Buy and Circuit City have combined!!). Of course, there are plenty of other brands to look at, but I would start with those. I've heard and read some things on Earthquake, but never owned, tons of good ink on MMATS, etc.
Oh well, first I would look into the probability of running 2 separate amps bridged. You can find good deals on the net from top brands: www.mmxpress.com and www.digitalwavez.com are 2 good places to look along with Wayne's Classified page.
good luck,

I've also noticed that 4 channel amps don't seem quite as tough as their pair of 2 channel equivelants. Oh well. 4 channels are still great versatility in a small package.

The thing is the speakers have dual 3 ohm voice coils, so I have to wire in series or just run one channel to each voice coil and that's not getting the amps full potential. I could always bridge a two-channel amp and run the voice coils parallel off of that channel, but then I'd need an amp that was stable at .75 ohms.
Crossfire is not a "budget amp". They may not cost alot but definitely not to be classified with Profile and Audiobahn.
My suggestion for an amp would be to look into either Crossfire or Planet Audio, and use a 2 Ohm Mono stable amp, Series the 2 3 ohm coils on each sub (6 ohms), then parallel the two subs together to get a 3 ohm mono load. I believe you can get a 200 watt Planet or Crossfire amp for about $229 msrp.
