I just bought this amp and hooked it up to my two rear speakers (pioneer 6.5's 160w each)...when i have the gain setting on minimum and my deck volume below about 16, the sound comes through the speakers just fine, but the minute i turn the volume up on my deck past 16 or so, the amp turns to protective mode and the sound stops coming through on my speakers. the amp is not overheating at all and i have played around with the settings trying to see if i can get it to play any louder than 16 (which is very quiet). Any ideas what the problem could be? thanks

The amp is going into protect on the two channels powering the speakers. Turn down the gain on those two channels. You also may want to consider crossing over the speakers a little higher than they are now.
The rating on those speakers are way too high. 6.5's and 6x9's will take 50-100 clean watts tops before they start to break up.
The best solution to get it perfect is....unplug the subs. Turn the gain on the speaker channels all the way down. Then turn up the deck 80% as high as it will go. Play a song. Then increase the gain on the amp until the speakers are as load as they go without distortion. Shut off the car, replugg in the subs and do the same thing. Gain on sub channels all the way down, deck then to 80%, find a bass heavy song, then turn gain up until subs become distorted. If you do this procedure your speakers and subs will be "gain matched" to the proper levels.
Guessing its the factory deck and it does not have rca outputs behind the deck .You get an adapter from speaker wires to rca with the gain setting on it from a car audio shop ,wire up you amplifier and connect the speaker wires to rca adapter from the closest speaker wires to the amplifier placement leaving the car speaker still connected though ( just tap into the speaker wires ) .Connect the rca from amp to adapter and set the gains on the adapter and you ready to play .
Yes....hook one up to the left channel and one up to the right.....once everything is wired up.....keep gain down on amp and turn stereo on.....turn up stereo with amp gain down to right before high end speakers start to distort......then while its playing, turn amp gain up about 1/2 way. close your trunk and hop in drivers seat....sound gd????? You might have to adjust level on amp and bass on head unit to taste.....Be careful though....pioneer subs are only rated around 300 watts continuous.....dont want to blow them...gd luck....
check the speakers in the rear deck, in the rear hatch or trunk, often the two wires that come out of the speaker touch if that happens it will short out the speaker drivers in the radio most times no permanant damage will occur. separate the wires so they do not touch,or touch the metal speker base, that may not be the problem but its a start..
In a radio like your Pioneer and all similar units there are always a pre-amp circuit that feeds a power amp circuit,In some players there are more than one pre-amp circiuts. It is possible and highly probable that the power amp circuit in your Pioneer is shorted, so you still get some audio output , but very little. I believe this is your problem and I suggest that you bring it to a repair shop for an estimate or replace the unit. Good luck and please rate this answer, Thanks.
you are better off setting your deck speakers amp to a high pass filter setting on the amp. Adjust gains to increase desired bass and clarity. Turn off loud button if you have one, that will distort your deck speakers.
This sounds like a gain setting problem on your amp. The best way to adjust is to set your volume on the head unit to about 75% volume and then adjust the gain up until it sounds distorted a little. Back it off jst enough for the distortion to go away and you are set. Only other thing to try is use a multimeter set on Ohms to test the resistance of your speaker configuration. Looks like 2000 is th peak power (not RMS) and is only possible at high current configurations. You are probably running at 4 Ohms, but this amp only puts out rated power at 1 ohm stereo or 2 ohm bridged. Many people say Performance Technique are overrated, so maybe not even what it is rated at - 350 x 2 @ 2 ohms bridged (probably only about 175 x 2 at 4 ohms bridged)
If you set the gain too high on the AMP, at loud volume levels some clipping or distortion of the output signal will occur. Most amps have a Circuit inside that detects this clipping or distortion and applies protection to prevent damage to the speakers and the amp. It would help to know if you are driving the speakers with a Line level output or using the speaker output from your deck. There are many things that can cause an amp to go into protect mode, and knowing a little more about your setup will help to solve the problem.
