i have a pioneer AVHP5100DVD as my cd player pioneer ts4672r, 4" x 6" 3 way speakers in the dash pioneer tsa1683r, 6 1/2", 4 way speakers in the doors pioneer tsa6993r, 6" x 9", 5 way speakers in rear panels i just bought a pioneer GM-6400F 4 channel amp heres the stats on it= GM Series 4-Channel Class AB Car Amplifier RMS Power Rating: 4 ohms: 60 watts x 4 chan. 2 ohms: 75 watts x 4 chan. Bridged, 4 ohms: 150 watts x 2 chan. Max power output: 600 watts PWM Regulated MOSFET power supply LED power indicators 4/3/2 channel operation Built-in crossover LPF/HPF (front/rear independent) Variable high-pass filter (cut off frequency: 80 Hz, -12 dB/octave) Variable low-pass filter (cut off frequency: 80 Hz, -12 dB/octave) Built-in speaker level inputs Hi-volt (400mV ~ 6.5v) input level control my subs= i have 4 12" kicker L7 solo baric subs, in a ported box built to specs! my amp= im running a planet audio, LS-VX2200D, its a •VX Series Single-Channel Monoblock Class D Car Amplifier •RMS Power Rating: ◦4 ohms: 800 watts x 1 chan. ◦2 ohms: 1200 watts x 1 chan. •Max power output: ◦2 ohms: 1750 watts x 1 chan. ◦1 ohms: 2250 watts x 1 chan. •High-current MOSFET power supply •Power and protection LED indicators •Tuned Bass EQ (0-18 dB bass boost) •Optically-isolated remote input •Single channel (monoblock) operation •Custom designed, multi filar-wound power transformers •Line out for Preamp RCA outputs •DC, short circuit, thermal, and reverse polarity protection •Fully regulated, pulse-width modulated power supply •Pure totem-pole drive from the PWM controller to the gates of the power MOSFETS •Multiple time-delay circuits and optically isolated current drive circuits ensure a quiet turn-on and turn-off cycle •35 Nanosecond rectifiers reduce losses in secondary circuits •Variable low-pass filter (50-150 Hz, 24 dB/octave) •Subsonic Filter (15-40 Hz, 24 dB/octave) •Frequency response: 20-250 Hz but my subs were professionaly wired at 2ohms in the box with only 2 sets of speaker wires coming out, he said he wired the subs together on each side with 1 set of speaker wires coming out either side. all this is in a 01' chevy blazer 2dr, 2wd, with a 3"/4" drop kit, and black 20" rims w/ chrome lip! i have pics of setup if they are needed. just email me and ill send them 2 u.
