Pioneer amp wont turn on after boosting a buddies battery

Still possibly a battery fault, radio uses about .3 amp, windows 3-5 amps, STARTER needs approx 30 amps. So a bad battery will power the auxiliaries but not the starter. Try a boost start from a known good battery and take it from there.

It might be the starter, if it gets too much use the armature might be too weak and need extra Amps to get it to work right.

When an amplifier shuts the Bass off that means its going into protection mode otherwise it will burn out the outputs. One way is to turn your gains down, Pioneer amps are not the best amps for bass out there, they are more for car speakers, I personally wont use a pioneer amp to run my subwoofers especially if they are hard driven subs like JL , Kicker Solo's and MTX subs. But for now just turn the gains down to 3/4 and that should help u, you can also install a fan to keep your amp cooler, if this never happened before in 5 yrs and now it does then that means your amp is just tired and the inside components are overheating easily, thats common with Pioneer and Sony amps.

Good luck buddy.

be sure the blue/white or blue if blue/white is not available is hooked up to the remote turn on of the amp

get a variable power supply(ac to dc) that will get you 11-14 volts . You wont need a lot of amperes to run the deck.I had a buddy that just used a little car battery charger in his shop when he was jammin in there-kinda ghetto but hey it worked fine

Hook fuel pressure gauge up to port near firewall. A battery charger sometimes boosts the vehicle voltage just enough to engage weak fuel pump. Should show 50-60 lbs all the time while cranking when not starting on battery.

The 670 amps will work, but will probably not last very long. It wont hurt anything except the battery itself. Make sure the cables polarity is connected right. A note on how to boost a car safely: ALWAYS START THE CAR FIRST THAT IS DOING THE BOOSTING. This ensure no computer damage will result on either car. Good luck.

they want you to "level match" the amps head units voltage from the rcas .this is best done with the radio at 3/4 volume , turning the amps gain dial till music distorts then backing off till it sound s clear .if theres other units in the signal chain (eq,x overs, ) see if they too have gain /volume controls . it goes down the line if thats the case . .

Hello fresttadefjm,

There are no subwoofer settings on the Pioneer DEH-2800MP.

You need to check the external power amplifier and the connections from the Pioneer and from the sub(s). If everything is plugged in and wired correctly, check the amp fuses, both on-board and the main power fuse (located in the amp positive lead usually near the vehicle battery).

Hope this helps.

did u have your remote wire hooked up right?
