Unplugged my headunit to work in dash now head unit flips out but does not come on and amps dont light up


Hi, sounds like you lost your amp turn on. Look for a blue, or a blue-white wire, that is your turn on and or power antenna wire. Turn on your strreo, check the output voltage with a meter on that wire. If you have voltage, check the battery power on your amp. If you dont have power on the turn on wire, use an acc. voltage that shuts off with the key. That should do the trick.

How to install jensen 40w+40w a-80


I have one of these new, in the box, with no instructions.

Specifications:
Power Output: 40W/Chan Maximum, 18W/Chan RMS
(20hz-20khz into 4 ohms at less than 1% THD)
Freq. Responce: 20hz-30khz, +/-3dB
Signal to noise ratio: 80dB, A-weighted
Input Sensitivity:
Low Level, 100-500 mV
High Level, 1-5v
Input Impedence:
Low Level, 10k ohms
High Level, 27 ohms
Load Impedence: 4-8 ohms allowable (4-8 ohm speakers)
Power Requirement: 14.4v DC (10.8-15.6 allowable)

As you can see the RMS wattage output of these units is only about 18W maximum.

I am planning on using the amp I have on a low power factory car radio. A low power factory radio output should be somewhere between 6-12 watts rms/channel. I will be using the "High Level" inputs for this. DO NOT connect a radio with a higher output power. If your radio says "High Power", 25W/channel, etc, do not connect to this amp. (exception: you can use the "line out" connectors, if so equipped, See Below). I don't have the connector for the high level input so i don't know what I'll do to hook up to it. I'll probably just run wires out of the amp, in lieu of the connector.

The "Low Level" inputs are for an unamplified, line level signal ("line out" connection of a radio, portable CD player, etc). Do Not connect a greatly amplified signal to these connections.

I don't know much about the "Input Sensitivity" control (pot). I'll be leaving it on "Low" for my initial test.

The grey wires are the right speaker wires and the white wires are the left speaker wires. The grey wire with a black tracer mark is the right speaker positive (+) wire. The white wire with a black tracer is the left speaker positive (+) wire.

The blue/white wire is for attachment to your radio's "Auto Ant" (power antenna) connection (usually a orange wire, I said USUALLY). If you have a power antenna on your car, simply splice into the wire running from your radio to the antenna. This blue/white wire activates a relay in the amp which, in turn, completes the circuit through the yellow (+) power wire (See Below). - Alternative 1: You could run this wire directly to your battery with a switch to turn the amp on. You would need to place an in-line fuse of 2amp. - Alternative 2: You could connect this wire to the accessory fuse in your fuse box. If this is done, again, attach a 2amp in-line fuse for extra protection. (Note: if attached to your fuse box accessory fuse, the amp will be on even if you're not using the radio. You could have a switch here also). These are just suggestions. The most common way to connect the blue/white wire is the "Auto Antenna" wire of your radio.

The large black wire is main Ground (-) for the amp. The large yellow wire is Positive (+) power to the amp. Ideally, these should be connected straight to your battery's (+) and (-) terminals. The yellow wire on your amp should have an integral in-line fuse holder with a 7amp fuse. If not, add one. Of course, the black ground wire could simply be attached under a screw, into the body of the vehicle.

Hope this helps !

not a fuse or relay problem but a flat/dead battery
have the battery load tested and have the charge circuit tested by an accredited auto electrician to ensure that it is charging the battery

I have power to the acc wire to the radio, but no power to the all time hot, I can't get any power to turn the radio on. I also don't have a diagram to check the fuses.


You shouldn't have any power from the acc wire. That wire is switched by the radio as an output if you had an accessory such as a power antenna or an amp.

What is the rem termial on a crunch amp


the terminal marked "rem" on most amplifiers (if not all) is for the remote signal.

The remote signal is a low current signal that tells the amp that the carstereo is "ON", this "activates" the Amplifier and turns it off again when the carstereo is turned off, if the amplifier stayed on all the time it would drain your battery while the car is off

so, anyway if your carstereo is enabled to work with an amplifier it should have one wire marked "remote" some brands use a blue wire for such purpose.

If you cant find wich one is the remote wire or you are using an original euipement manufacturer (OEM) carstereo, you need a test licght to check wich wire puts out current when the carstereo is on and switches it off when you turn off the unit, that should be the remote wire.

it is advisable to use that signal to operate a relay instead of directly using the remote wire on the amp, but its more of a security/professional install kind of motive.. so if you understand relays go for it, if not, go ahead and connect the remote to the amp... NOTE: THIS WAY IF YOU SHORT THE REMOTE WIRE YOU RISK DAMAGING THE CONNECTION OF THE REMOTE INSIDE THE HEAD UNIT...

PS: i use carstereo, unit and Head unit as synonyms because english isnt my native language and here we just call them "stereos" but thats just wrong

Amp shuts off when switched from radio to cd


your amps rem wire is hooked to the power antenna wire on your head unit and so when you turn off the radio you would nolonger need an antenna so it powers down and would lower the antenna.Depending on the head unit you should have one output for the power antenna and one for the amp rem......If your head unit doesn't have the rem output you can wire it to the switched wire that powers your head unit but keep in mind the amp will stay on while you have the key in acc or run position even if your head unit is off.
hope this helps!

No amp for cd or usb


This is generally caused by using the wrong switched output. If the head unit has both a power antenna control output AND an amp control output, you need to use the amp control output to feed the remote turn-on input on the amp. On head units that have both types of outputs, the power antenna output goes off when you switch from radio to a source that doesn't need the antenna.
