Help please - deciding between 2 amps

[koochkooch]

So this is my set up:

- 2x Component speakers front - 80 watts RMS at 4 ohms each (160RMS for pair)

- 2x Coaxial speakers back - 55 watts RMS at 4 ohms (110RMS pair)

I'm trying to decide between two 4-channel amps to power these speakers:

-JVC KS-AX5104 - Class A/B.

• 70W x 4 into 4 ohms at 20 - 20,000Hz,

• 100W x 4 into 2 ohms at 20 - 20,000Hz ,

• 200W x 2 into 4 ohms at 20 - 20.000Hz Bridged

-Pioneer GM-D8604 - Class D

• 100 watts RMS x 4 at 4 ohms

• 150 watts RMS x 4 at 2 ohms

• 125 watts RMS x 4 at 1 ohm

• 300 watts RMS x 2 bridged at 4 ohms (250 watts RMS x 2 bridged at 2 ohms)

Buying the first amp would save me $200, but will it be sufficient for my setup? Is it worth going for the class D rather than A/B? The Pioneer amp has massively positive reviews, while the only review I could find of the JVC was on amazon at 3/5 stars. What do you guys recommend? Is it worth forking out an extra $200?

idk where you're getting that $200 difference

Pioneer is 122 from walmart with free shipping

JVC is 119 from sonic electronix

I'm based in NZ and managed to find a good deal on the JVC unit secondhand, while the pioneer i'd have to buy brand new from a supplier.

I'd like just like to know which of the two I should choose, rather than hearing about any alternative amps.

Cheers

Are there any differences in performance between the two?

The Pioneer will be more efficient and put out more wattage being class D than the JVC class AB amp but at the level of power you’re talking about running efficiency shouldn’t be a very big factor.

one does an actual 100 watts a channel aka pioneer and the other does 20 real watts per channel at best.

If it were me, I'd choose the Pioneer. If there's something better that you can get ahold of, let us know and we can tell ya if it's good or bad.

yeah pioneer maybe better and may not **** any more power than the a/b amp but $200 diff is silly, we can get ppi 145x4 for $160..

Nothing major.

70 vs 100w on your components would probably amount to a noticeable, but not drastic difference.

Rears, no difference.

Otherwise, should be pretty similar in-car.

Pio is quite a bit smaller.

No.
