Would it be worth switching?

[AnthonyO 10+ year member]

Right now I have an AudioControl ACM4.300
50 Watts RMS x 4 @ 4 ohms
• 175 Watts RMS x 2 @ 2 ohms
• 150 Watts RMS x 2 @ 4 ohms, Bridged
• Small Footprint for Flexible Mounting
• AccuBASS and GTO Signal Sense Built In
• Linkwitz-Riley Crossover
• Aluminum Heatsink
• Dimensions: 9.4" W x 3" L x 1.75" H

Looking at D'Amore Engineering E400.4

• 60 Watts X 4 continuous into 4 ohms
• 100 Watts X 4 continuous into 2 ohms
• 200 Watts X 2 continuous into 4 ohms bridged

Dimensions 9.3 x 5.3 x 1.9 inches

The E400.4 dynos at over 70 watts a channel

Also,
Looking to switch the Stinger MT1000.1 to the MT1500.1
Subs need a little more umph


I am rewiring this summer to my 2 gauge welding cable to distribution and 4 gauge out to the amps.

The differences in the 4 channel amplifiers would be minimal. Might not even be noticeable to the ear. I probably wouldn’t bother doing it.

Every dyno test I've ever watched on the ACM 4.300 indicates it is very underrated. You will not hear any difference at all in my opinion. A doubling of power is needed to create a 3 db difference to the ear, 9-10 for a perceived doubling of the volume.

50 to 100 x 4 for 3db
100 to 200 x 4 for 6db
200 to 400 x 4 for 9db.

The Sundown SFB-1000.4D will get you close to double volume (not like you can or will actually be able to do this, but...)

That said, I did notice a difference when I went from the ACM 4.300 to the Soundigital 2000.4 Evox for sure. Detuned a bit, but my midbass drivers really came to life with the extra power and I always like the versatility of having more power than I can use.

I wouldn't switch 4 channels unless you're at least doubling the power.

And the monoblock...I'd do 2k and dial it back to where you need

Deff not going to hear much of a difference of the 4 ch amplifiers unless you are going to 100 rms per ch. With 10 watts, its just not worth the effort nor the expense. The CT Sounds 150.4 is fairly compact and decently priced with great power on tap for the money. I enjoy mine.
