Looking for a new amp to power my fronts and mids.
These are the ones I'm looking at:
Boston Acoustics GT-4100
Number Of Channels:
4 Channels
4 Ch. Power @ 4-ohm (CEA-2006-A):
100 Watts x 4
4 Ch. Power @ 2-ohm (CEA-2006-A):
150 Watts x 4
Mono Power @ 4-ohm(CEA-2006-A):
300 Watts x 2
Mono Power @ 2-ohm (CEA-2006-A):
450 Watts x 2
Mixed Operation Power (CEA-2006-A)
100 Watts x 2 (4ohm)& 450 Watts x 1 (2ohm)
4 Ch. Power @ 4-ohm (12vdc)
85 Watts x 2
Frequency Response (-3dB):
10Hz-95kHz
Signal to Noise Ratio (A Weighted):
>100dB
Lowpass Crossover:
12dB Adj. (50Hz to 350Hz)
Highpass Crossover:
12dB Adj. (20Hz to 250Hz)
Q-Tune:
Adj. HP Q (0.707 to 1.6)
Kicker ZX650.4
RMS Power Rating (@ 14.4V):
Infinity Kappa Four
Specifications
• 125W RMS x 4 channels @ 4 ohms
• 150W RMS x 4 channels @ 2 ohms
• Frequency response: 10 to 75kHz (-3dB)
• THD + N: 0.05%
• Signal-to-noise ratio: 85dBA (reference to 1 watt)
• Signal-to-noise ratio: 106dBA (reference to rated power)
* CEA-2006A-compliant
Soundstream REF4.760
Channels 4
RMS Power @ 4Ω, 14.4V 4 x 115
RMS Power @ 2Ω, 14.4V 4 x 155
RMS Power @ 4Ω Bridged, 14.4V 2 x 380
RMS Power @ 1Ω, 14.4V -
Total Harmonic Distortion (4Ω power) 0.02%
Frequency Response 15-50kHz
Signal-to-Noise Ratio (4Ω power) 102dB
Damping Factor (100Hz, 4Ω)
Dimensions: 2.25"h x 9.875" 55mm x 250mm 20.25" 514.5mm
Ch. 1&2 HPF/Hawkins/Subsonic (12dB Slope / 0-10dB Hawkins Boost) 15Hz-4kHz
Channels 1&2 LPF* (12dB Slope) -
Channels 3&4 HPF* (12dB Slope) 15Hz-4kHz
Channels 3&4 LPF* (12dB Slope) 50Hz-4kHz
I'm leaning towards the Soundstream because It's a nice amp and I can get a hell of a deal or the Boston because it's 1ohm stereo/2ohm mono stable making it very versatile. I could use it for other applications later if I'm not happy with it in this capacity. However the Kicker is nice as well and has a 2 yr warranty.
