I recently returned a refurbished Sony Xplod amp, because it made speakers crackle/pop, and now I'm in the market for a good quality 4 channel amp(not that Sony isn't good quality) to power my 4 Alpine speakers and Sony sub. I've come down to the Pioneer GM-6500F and the Alpine MRP-f300. Here are the specs for each
Pioneer:
4-channel car amplifier
60 watts RMS x 4 at 4 ohms (85 watts RMS x 4 at 2 ohms)
180 watts RMS x 2 in bridged mode (4-ohm stable in bridged mode)
CEA-2006 compliant
4-channel variable high- and low-pass filters (40-500 Hz, 12 dB per octave)
MOSFET power supply
speaker-level inputs
preamp inputs
Alpine:
4-channel car amplifier
50 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 (4-ohm stable in bridged mode)
2-, 3-, or 4-channel output
variable high-pass/low-pass filters (50-400 Hz, 12 dB/octave)
selectable bass boost (12 dB at 50 Hz)
subsonic filter (15 Hz, 18 dB/octave for channels 3 & 4)
MOSFET power supply
CEA-2006 compliant
STAR Topology (minimizes internal noise and prevents ground interference)
speaker- and preamp-level inputs
gold-plated screw terminals
I should mention my budget is no more than $140. I'm also looking at the Kenwood KAC-8405, and Pioneer GM-D8604( 100 watts RMS x 4 at 4 ohms), selling for $140 shipped at Amazon. Which amp do you guys think will perform better? The Pioneer GM-D8604 puts out most power (100 watts RMS x 4 at 4 ohms). Is the more power generally the better?Could this be a deciding factor? I'm leaning towards the Alpine, but if my setup could benefit from the extra juice both Pioneers put out, I might go with one of the Pioneers. Also, the Alpine has bass boost. If I use it very sparingly, could the bass boost be a nice bonus? Thank you!
