What I'm looking for: I have 4 Alpine Type S speakers (40W RMS) and
...later on, I'm going to get a pair of CDT CL-61A's for the front (90W RMS) and either nothing in the back or a pair of CL-6's (just the midrange speaker) running of the HU.
so the choices i've been looking at are...
1) Fosgate: 301X
40 watts RMS x 4 at 4 ohms
* 75 watts RMS x 4 at 2 ohms
* 150 watts RMS x 2 bridged output at 4 ohms
* 2-, 3-, or 4-channel output
* 4-ohm stable in bridged mode
* Tri-Way capable
* requires 10-gauge power and ground leads — wiring and hardware not included with amplifier
* front and rear switchable high-pass (120 Hz, 12 dB/octave) and low-pass (80 Hz, 12 dB/octave) crossovers
* MOSFET power supply and output devices
* Maximum Efficiency Heat Sink Application (MEHSA) mounting technology increases the heat transfer from the MOSFET output devices to the heat sink, for higher power output, lower operating temperatures, and greater reliability
* TOPAZ — noise-killing differential inputs that eliminate 80% of ground loop noise
* Trans•ana circuitry keeps preamp voltages low and signal paths simple for outstanding audio quality
* NOMAD — advanced protection circuitry for "intelligent" shutdown protection
* speaker- and preamp-level inputs
* preamp outputs
* 12-1/16"W x 2-3/8"H x
$120
2) Profile: CL440
RMS Power Output (Watts x Channels) 50 x 4
* Frequency Response N/A
* THD at Rated RMS Power 0.07%
* Signal to Noise Ratio 105 dB
* Input Voltage 14.4v
* Peak Power Output (Watts x Channels) 100 x 4
* Power at 2 Ohms (Watts x Channels) 75 x 4
* Bridged Power (Watts x Channels) 150 x 2
* Minimum Impedance Bridged 4
* Minimum Impedance Unbridged 2
* Features
* Amplifier Class AB
* Tri-Mode Capable Yes x 2
* Low-Pass Crossover Frequency 40-500 Hz
* Low-Pass Slope (dB/octave) 12 dB
* High-Pass Crossover Frequency 40-500 Hz
* High-Pass Slope (dB/octave) 12 dB
* Bass Boost 0-18 dB
* Bass Boost Frequency 45 Hz
* Fan Cooled No
* Fuse Rating 20 x 2
* Speaker Level Inputs Yes
* Preamp Outputs 1 pair
* LED Power Indicator Yes
* Height (inches) 2-5/8
* Width (inches) 12-5/8
* Length (inches)
$97
3) or drop an extra $80 for a Fosgate 551X for $200 for (70W x 4 RMS) (275W x 2 RMS)
