Amp suggestions please
Does anyone know of a 150x4 chan amp @ 4 ohms, that you can bridge 2 of the channels into 300w, that is stable with a 1.5 ohm amp load? =)
(and ideally its dimensions are less than 22"L x 10"W)
I'd like to run a DVC 6ohm JL 12w6 on 2 of the channels bridged...
Thanks

It just happens to work out the components im going to use eat about 150w and the sub requires about 300w. (thus the 150x4@4ohm)

oh sorry, i read it quickly. i see what you're trying to do...problem is, finding an amp that will run 1.5 ohms bridged. I think zapco would modify an amp..but for a price... and at the cost of sq too

PG amps have been known for 1 ohm stability bridged. I have not kept up with their reputation lately, I know they now have a "cheap" line. 
PPI and Orion come to mind as being able to come close to what you want.
That 1.5 ohm crap on the JL sub is designed to work best with JL amps.

I also have a PG Titanium 400.2 left over. I really wanted to get a JL 250/1 Slash and use the PG Ti, but I dont think there is enough room on the back board of the trunk to mount them side by side vertically.
Thoughts?

Do you just have 1 sub or 2? Because if you've only got one, you're just looking for stable at 3 ohms bridged, not 1.5.
My very first sub was a 12w6 D6, ran it at 3 ohms on my RF 360a2, insanely loud
Also, finding something that does 150 x 4 @ 4 ohms(likely going to be around 250 x 4 @ 2 ohms or 500 x 2 @ 4 ohms), you'll end up with a configuration like this:
Front two channels: 150 x 2 @ 2 ohms.
Rear two channels bridged: 600ish x 1 @ 3 ohms
600ish because I'm guessing the amplifier you're looking for won't actually rate their channels at 3 ohms bridged and it's kinda hard to make up the #. Could be anywhere from the 500 it'd do at 4 ohms up to about 800.
What kind of speakers are you running up front? You could probably do with a bit smaller amp and still have great SQ.

JL will run the 12w6 D6 and the PG will run the Focal 165 K2P's. I have a Pioneer Premier DEH-940MP and a Audiocontrol 3.1 in the dash.
Managed to pull up all the carpet in the trunk today and dynomat half of it, fingers hurt like hell but I'm hoping it will be worth it
