Ok you audio gurus..I need suggestions on a GOOD amp that wont break the bank.
Im leaning towards running at least a 400x4 amp to power some front CDT components and a 10" sub. I have been looking at Phoenix Gold but they seem to be waaaay too over priced. Any suggestions?

JL amps are very nice, but depending on the PG amps you were looking at, they will be even more expensive. The JL500/5 doesn't have enough juice to run a sub IMO. If you want to the JL route, I'd go with a 300/2 and a 500/1. You will get much more power and the price will be the same, if not less than a single 500/5.
I have little eperience with PG, but I know they have a "good, better, and best" line. Did you look at the Phoenix Gold Octane-R R9.0:5? For $300 its 125x4 plus 400x1 for a sub (make sure you use a 4ohm DVC sub @ 2 ohms).
Other bang for the buck amps are:
US Acoustics USB-2150. You can get two of them for $300 at Crutchfield, and likely a lot less than that someplace else.
Use one for the CDTs at 150wattsx2 and bridge the other one at 450x1 for the sub.
Or JBL P180.2. Use one for the CDTs at 90wattsx2 and bridge the other at 360wattsx1 for the sub. JBL amps are slighly underratted, so expect more like 100x2 and 380x1. You can get two of them from ikesound.com for $268.
I'd go with the JBLs over the US acoustics. I've heard good and bad about the US acoustics amps, but am very happy with my JBLs.

I would not get 4 channels amp. Get a 2 channels amp and a mono amp.
From the same series same power, the 2 channel amp always sounds much better than a 4 channels amp.

Ok, I was at a shop today looking at a Phoenix Gold Octane 80x4 amp and a Phoenix Gold Octane 10" sub. What do you guys think about PG stuff? The dude says that the 80x4 will be plenty of power sending 80 to each CDT and bridged 320 to the sub. I can get both for $370. Good deal or no?

Amp yes... go with something else on the sub. My $.02

How is a single 80x4 amp going to send 80x2 and 320x1. I think you misunderstood him.
I was just at the PG site and the only 80x4 Octane amp I could find was the R5.0:4. The 80x4 rating is actually a maximum power output rating. The RMS rating is 50x4 with each bridged channel only getting 150 RMS. This is not something I would want to run.

Nope, he is right.
Most high quality amps will do that quadupling (spelling?)
IE I have a PPI 2150 which is a 150 X 2 or 600 X 1.
I have a US Acoustic 2150 which is 150 X 2 or 450 X 1.
I hope this helps.

I have been using PG for the last couple of years now and I have been really happy with them. Good clean solid power. I just purchased a PG Titanium500.1 for my new system. It will be used to power a 12" Diamond Audio sub and a pair of Diamond Audio hex components in the front. No speakers in the rear. Good luck with your system.

The specs are right in theory.
In a perfect world, the amp power should double when you combine 2 channels and then double again when you devide the impedance by 2 (which automatically happens when you bridge an amp). So in the case of the PPI 2150, its 150x2 @ 4 ohms per channel. And when you bridge it is actually 300 watts x 1 4 ohm channel, but since the channels are combined, the impedance drops in half. So hooking up a 4 ohm sub make the amp "see" a 2 ohm load and double its power from 300 watts to 600 watts (it also doubles the %THD, but we don't need to get into that).
In this case of this PG amp that is 80x4 (lets pretend thats RMS power) the front 2 channels are 80x2 @ 4 ohms. The rear channels are to be bridged at 160x1 channel @ 4 ohms. Since the channels are bridged, the impedance drops in half, so the rear 2 bridged 2 channels of the amp now produce 320 watts to a 4 ohm sub.
It is important to remember that when you bridge an amp like this, the amp is less stable and has increased %THD.

Ok...I think I found the amp. Its a PG Octane R8.4 and here are its specs.
•125W x 4 (4 ohm stereo)
•400W x 2(4 ohm bridged)
• Grained aluminum insert
• Carbon fiber badge, backlit with blue LED
• Optional neon inserts for all amp models
• Overload and comparator circuitry
• Full range thru output
• Remote monitoring Display (RMD) port
• Twin "T" bass circuitry at 45Hz
• 4 channel power amplifier
• 12dB HP/LP variable crossovers
• Full range aux output
• Dimensions: 15.75L x 10.875W x 2.25H
This should be plenty of power and the amp is only $220 at woofersetc.!!
RMS power output is 75x4 (4 Ohms). So thats 75 up front and 300 bridged to the sub.
Oh, and I think the sub I will be running will be a 10" JL W6. I found one for $180.
What do you all think about that set up? :confused:
Oh and Rbartick those specs you got are for the R5.4 which was the first one I was looking at not the R8 which you have listed.
Re: Ok you audio gurus..I need suggestions on a GOOD amp that wont break the bank. (BIG LAW MAN)
Well, it is your money but I would not get the Octane series ... look like it is the low level of PG. Compare to the same power at the PG Ti series for 700$.
Try some other brand and get the top of the line.
JL 300/4 or Eclipse premium series ... those amps are running at the same price around 250$ and they are top of the line series.
Just my 0.02$

Yeah, I put the correct model # in my first post but I put the wrong model # in my second post. I just corrected it.
The specs on the R8.4 say 75x4 RMS at 4-ohms and 250x2 Bridged @ 4-ohms. That means if you bridge one set of speakers outputs to a sub it will be getting about 250W.

Thanks for your advice. Please tell me where you are finding the JL 300/4 for $250? Woofersetc. is selling that for $400!
