4 channel amp question

[sstumpf]

First, I have a diamond d6 600.4 amp. it started about a week ago turning on sometimes and sometimes not. Now today it didn't turn on at all. My other amp works perfectly fine. and the diamond amp always has power, I tested with dmm. The ground is good. and the REM wire is good. is there anything that im missing? or is this amp done?

Second, If im buying a new amp. What would you guys recommend. For now I am just running a set of Image Dynamics ctx65cs off of it, Which are 100w rms. The diamond amp did 75w rms. so I guess im looking for a 4 channel in between 75 and 100w rms. I want a 4 channel in case I decide to add a rear set. I would like to stay at or under $200 if possible. Im looking at this one.

Gmd8604. PPI 900.4 are good ones for that price.

PPI ph900.4 ......

 

[sstumpf]

Ok, I will look into those. I was considering that pioneer too. from what I can see on the reviews. It looks pretty decent

 

[Boominburban]

I've had my 900.4 on my test bench, and can back up these reviews ....

I've heard good things about the massive nx4

 

[sstumpf]

Ok well I have narrowed it down to these. Only because I would like something that is on amazon prime. So I can get it Tuesday. Dont want to wait another week with no speakers. I think im leaning towards the pioneer.

+1 ppi900.4 best power output for the money.

ive had the pad40004 and the ppi900.4 (both are basically the big brother of what you're looking at) and I can tell you that the boards they use are exactly the same besides the case and possibly some minor differences in the components on the board. I didn't notice any difference between the two, exact same crossover options, sq, output, and footprint.

 

[sstumpf]

well lots of good things are being said about the ppi. I also found it on prime. so its between these two.

PPi 900.4

Pioneer GM-D8604

The only thing about the ppi is that its rated a little higher than my ID comp set. But I should be fine with it right?

Perfectly fine. Just set the gains and everything right and you are good to go

 

[wew lad 5,000+ posts]

set the gain lower and you'll get less distortion with the same power you'd get from another amp costing more lol

it was bench tested here: PASMAG | PERFORMANCE AUTO AND SOUND - Precision Power P900.4 Amplifier

ok, well im just going to go with the ppi then. looks like it should do good.

It's also active capable. I really like mine.

Don't know if they still have them, but I ordered the polk one. Straight from polk on eBay. It's a refurbished item but it was only $80, shipping included. Don't know if you've ordered the ppi or not.

It is class ab vs class D on the ppi. It's a good deal though.

nope doesn't look like they still have them. But I did go ahead and order the PPI. It will be here on Tuesday.
