Hello all...I currently have two amps in my possesion and I am only going to keep one of them. I have a Cerwin Vega Stealth 440.4 and a soundstream stealth stl4.500.

•Soundstream Stealth Series 4-Channel Class A/B Car Amplifier
•RMS Power Rating: ◦4 ohms: 80 watts x 4 chan.
◦2 ohms: 125 watts x 4 chan.
◦Bridged, 4 ohms: 250 watts x 2 chan.
•Full MOSFET Power Supply
•Double side PCB and SMD components
•LED power (green) and protect (red) indicators
•4-Channel operation
•Black anodized finish w/ chrome accents
•Active X-over function
•3-Way System Protection circuitry (thermal, overload, high/low voltage)
•Stackable chassis for multiple amplifier applications
•Heavy duty aluminum alloy heatsink for extreme heat dissipation
•Nickel-plated RCA level inputs
•Nickel-plated screw terminals
•RoHS compliant device
•Selectable high-pass filter (Front 50-4000 Hz, Rear 15-500 Hz)
•Selectable low-pass filter (Front 50-4000 Hz, Rear 50-800 Hz or 250-4000 Hz)
•Subsonic Filter (Front 50-4000 Hz, Rear 15-500 Hz)
•Bass boost frequency: 50 Hz
•Bass boost level: 0, 6, 12 dB
•Signal-to-noise ratio: >100 dB
•THD (Total harmonic distortion): 0.05%
•Damping factor: >200
•Frequency response: 15-25,000 Hz
•Dimensions: 11-1/4"L x 6-1/2"W x 2-1/8"H

•Stealth Series 4-Channel Class D Car Amplifier
•RMS Power Rating: ◦4 ohms: 65 watts x 4 chan.
◦2 ohms: 110 watts x 4 chan.

•RMS Total Output: 440 Watts
•Full Pulse Width Modulated (PWM) MOSFET Power supply
•LED power and protection indicators with built in overload protection
•Vega Bass adjustment (0-12 dB bass boost)
•Crossover selection switch allows you to adjust the crossover point
•Input gain adjustment allows for more precise adjustments
•RCA Input and pass-thru output allow for normal RCA left and right channel signal input
•Aluminum alloy casing great for fast heat dissipation
•Power input connections
•Standard ATC/ATO automotive 25A power fuses
•Silver-plated RCA level inputs
•Silver-plated screw terminals
•Variable high-pass filter (50-250 Hz)
•Variable low-pass filter (50-250 Hz)
•Frequency response: 20-30,000 Hz
•Dimensions: 9-7/16"L x 7"W x 1-7/8"H

I plan to run the amp in 3 ch mode to kenwood components that are 80w RMS and bridge the rears to an 8" jbl gto sub. I know both has enough power for the sub, but will a 15w difference on the components make it any difference? Which would you keep and why? Thanks

As stated, there isn't that much difference between them so go to what you like and sell the other. Glws.

the vega's a class d, so it should run cooler.
the SS has a better xover, should you decide to upgrade one day.

i'd keep the one that looks prettier.

It would be difficult to tell the difference in output if you swapped them, though the difference in wattage would be more for the sub bridged. Still I agree with above and would not weigh that little power difference as that important in your choice. I like my class D kappa, it is smaller and runs cool, at 4x125 the power is very good. So you could sell both and go larger lol.

Thanks for the replies everyone. I think I have decided to keep the Vega amp. I did alot of searching and it was the only one of the two I found that had actual bench tests done with the charts displayed and not someone just saying that it does rated. I think class d would be better also for the 12 hour round trip I take to visit family about 4 times per year. I fear the class A/B might go into thermal protect much quicker.
