Sound quality and volume intemittently improve

Hi I have a Panasonic CQVD6503U hoofed to a GM-6300f going to 4 Boston Acoustic 4 ohm speakers rater for 60W rms each.
most of the time the stereo sounds nice but every now and then usually after the vehicle has been running a while the sound quality and volume increase about 30% (going by the increments on the volume).

Hi there, i have a orion cobalt 2105xp 400. i have hooked all up, but very little bass. i have 1 10" boston acoustic sub. i noticed that the led is constant red, is it supposed to be green, crossover...

amp is in protect mode. check your wiring and make sure your sub is wired properly for ohms. dual 4 ohm in parallel = 2ohm. dual 4 in series is 8 ohms. dual 2 ohm parallel= 0.5 ohms and in series 4 ohms. check ground and power wires. make sure sub isnt blown. a blown sub WILL cause this on any amp.

I have speakers that have 60wattsrms@4ohms if i hook them up to this amp (xm-zr704)will i blow them?

Surlely you can connect these speaker to this amp . Your amp will deliver 150w at 4 ohms if you use 4 speaker setup. So keep in mind that, don't go for a high volume level. If you need higih volume level go for a speaker which will handle 150 w.

Amp comes on running 2 12" 450 watt pioneer subs, volume only seems to be about half output, with speakers bridged

This could be the reason. If you look at the specs for this amp you will see that the continuous power out is rated for 380W bridged. The speakers rated at 450W should be able to handle close to 315W continuous. Now if you split these numbers being you have bridged these speakers, you drive each one up to about 190W continuous. The speakers are being driven approximately by 60% of the rated capability. I personally like to keep it right where you got it, not exceeding 80% of the speakers rated capacity.

Here are the specs for the AMP:
  • Specifications
  • Peak Music Power 760 Watts
  • Number of Channels 2
  • Load Impedance Capability 2~8 Ohm (Stereo), 4~8 Ohm (Bridged)
  • Continuous Power (4 ohm) 125W x 2
  • Continuous Power (2 ohm) 190W x 2
  • Continuous Power Bridged (4 ohm) 380W x 1
  • Frequency Response 10Hz ~ 50kHz
  • Total Harmonic Distortion 0.008%
  • Signal-to-Noise Ratio 100dB
  • Dimensions 12" x 2-3/8" x 12-3/4"
  • Features
  • Bridgeable
  • Channel # Capability 1/2/3
  • PWM Regulated MOSFET Power Supply
  • Screw-Type Speaker Terminals
  • Balanced Isolator Input Circuit
  • RCA Inputs 2 Channel
  • Input Level Control Hi-Volt (200mV ~ 6.5v)
  • Built-in Crossover Selectable LPF (80Hz, -12dB/Oct.)

    I am having trouble hookin a 4 channel amp used to how do i hook it up

    the same thing as hooking up your monoblocks, the only difference is your having 4 outputs, that means you can drive up to 4 speakers with this one.

    Pioneer car audio amp GM 6300F (new)

    Does your amplifier have a Channel swith which says 2/3/4 channel mode. If so and you are running the amplifier in Bridged mode, try changing the setting to 2 channel or Bridged mode.

    Alpine PDX1.600 amp cuts off

    Make sure there's no missmatched impedance. If your sub running 2 ohms then your amp has to be 2 ohms stable. Does the amp blow fuses or get really hot? If it does it can be a fire hazard and I would recommend taking it out of your car. It could be that you don't have sufficient grounding. The grounding needs to be very close to the amp and the paint needs to be thoroughly scratched off. Otherwise could be a blown transistor within the amplifier, you can check this by opening up the amp, running a multimeter and testing the transistors for resistance.

    What are the correct spaekers for the gm 5100t ?

      CEA-2006 Compliant Amplifier Power Standard:
    • 125 Watts x 2 @ 4 ohms <= 1% THD+N
    • 380 Watts x 1 @ 4 ohms BRIDGE <=1% THD+N
    • 75 dBA Signal-to-Noise Ratio
    • Peak Music Power: 250W x 2 (4 ohm) / 760W x 1 (Bridge)
    • 2 Channels
    • Continuous Power @ 4 Ohm: 125W x 2
    • Continuous Power @ 2 Ohm: 190W x 2
    • Continuous Power Bridged @ 4 Ohm: 380W x 1
    • Frequency Response: 10Hz-50kHz
    • THD (1kHz, 4 Ohm): <0.015%
    • Signal to Noise Ratio: >95dB
    • Dimensions: 11 13/16” x 2 3/8” x 12 7/8”
    • PWM Regulated MOSFET Power Supply
    • Balanced Isolator Input Circuit
    • Oversized Screw-Type Power/Ground Terminals
    • 2 Channel RCA Inputs
    • Speaker Level Input
    • Screw-Type Speaker Terminals
    • Hi-Volt Input Level Control (200mV-6.5V)
    • Bass Boost (50Hz, 0/6/12dB)
    • Selectable LPF (80Hz, -12dB/Oct.)
    • Pioneer 1-Year Warranty
    I'm assuming the subwoofers were bridged and couldn't handle the power. Make sure you have atleast 300 watts peak power wattage.

    Hits intemittently

    ive had problems kinda like this ... normaly its a crossed or reversed speaker wire check the positive and negitive wire into the speakers "they move sometimes when there is more air moving around the speaker"

    second make sure you have the impedence correct "possitive to positive negitive to negitive'

    hope this helps
