Pioneer Amp + Sub Not Working

[Mr.Massive]

pioneer Amp (GM-3300T) plugged into pioneer Deck (DEH-7900,) through RCA cables and system control. Amp plugged into battery and grounded. Bridged wiring cables conected to sub. - Pioneer 6x9 also powered through the cars standard system (not amp)

This system was working in my old car (lancer) but i had a different pioneer deck. That shouldnt really matter but this set up is still not working in my R33?

The amp is working as the blue light comes on for power, and small beats are sent to the sub but are immediatly cut off by something as you crank the volume up.

Have i forgotten something? I havent had this deck for long and i am beginning to think this is the problem.

any help or advice would be appreciated thanx.

This sounds very familiar to what happens to my brother system. As soon as he gets a big hit of base the amp goes into "self protect" mode and cuts out then fades back in. Must have something to do with cabling or a fuse. Going to install his system in his new car and make sure everything is done right.

Check your wiring and stuff to make sure its not shorting out. The fuses and things aswell

another problem may be the heat affecting it. Make sure they aren't heating up too much.

Check the amp to make sure the treble/bass/EQ adjustment things are still set on the proper levels (if yours have these which i think they do in that series of pioneer)

But main thing should be (if it was already working in the other car) then there might be a short somewhere.

That's where i would start first

its cutting out because its pumping too much, check the amp, does it have a db controller? or something?

turn the setting down, and work your way up until it doesnt cut out..and make sure theres no treble coming out off the sub..

it happened to my old amp..shuts off to safe mode. see how that goes..

krzysiu : Your brothers problem was probly due to an inadequate power supply,earth or to low a load placed on the amp.

viet_boi : As mr.massive said its not "pumping" at all, it sounds like your refuring to the gain control.

on that model amp it should have a switch for LPF or HPF set it to LPF. Start by turning the gain nob all the way down.turn the volume up on the head unit to a level thats just abit louder then what you would normally listen to it,

then start to turn the gain nob up on the amp until the sub blends with the rest of the system nicly without overpowering everything else.now be carful not to turn it up too much to the point where it starts distorting.

If your still not getting anything from the amp here are a few more things to check, make sure the amp is earthed to a nice thick bolt that has had the paint sanded around it away so there is bear metal showing.

On that amp it is clearly marked what terminals to use to bridge it for use with a sub so make sure it is correctly wired up.

if none of that has worked,make sure there isnt a setting in the head unit that has the sub turned off or the sub control turned all the way down.

Where abouts are you located mate?
