I have 2 12in kenwoods and a 1200 watt pyrimade amp, how can i hook these up to be the loudest

1st have your subs facing inwards towards the front of the car, not facing out the boot, This creates a better bass.

Wire 1 sub to one channel and the other sub to the other channel.

Turn down your gain as low as possible and then power everything up.

turn volume to desired loudness and then start turning up the gain slowly, if distorts a little turn in back down a notch.

avoid using bass boost, I agree it sounds great but it puts more strain on your amp and shortens its life.

after sorting out your gain, tweak all others until sound is bassy and clear with no distortion.

If you would like to use bass boost, turn on bass boost first, then up your gain etc.

KAC9103d been running great for a year, factory refurb. for a month been losing sub output. checked all connections again, everything good. Turned on went driving 15 minutes later lost bass ckd again red...

Could be that you have a partially roasted(blown) coil on one of your subs which will function- but will keep tripping your amp.You can check that out just by using a different set of subs to listen to and by the process of elimination if the problem goes away then you know where the problem is at.Also check your gains you might be riding the gain a little high which causes distortion which causes heat(FAST) which will cause the amp to shut down completely or some amps will decrease output in a programmed attempt to save itself.turn the bass boost down to half if you even use it at all- that too can cause massive distortion in the amp itself,meaning only that if you have the bass boost on your deck turned up and then you turn the boost up on your amp the sound signal is then WAYYY distorted which will cause a thermal shutdown too. Last thing is to make sure that your subs arent running below 2 ohms because i believe that particular amp is designed to put out about 900 watts at 2 ohms.good luck

Subs sounded great then someone tweeked the amp and it sounds horrible. What is the proper way to start from scratch to set up the amp. LSX-2400 800 watt Logic Sound Lab.

turn all your gains, bass, and low pass filters all the way down. then turn your gains up until you hear distortion from the speakers, its called clipping. once you hear this, slowly back the gains down until you hear no more distortion, and then tune your low passes, and your bass to your preferences

Amp cuts off

sounds like you are overheating the amp, if the amp has a fan to cool it off, make sure it is turning on and working... if it is not then replace the fan to fix the problem...also turn the amp gain down a little bit and try running it again and see if it still shuts off...if it doesn't shut off then you have teh gain to high and are cutting out the amp with to much power going thru it...

Need help (autotek mx1300)

find the input gain controls, theyre usually recessed into little holes, so you have to stick a small regular screwdriver into each of the holes to turn up both the left and right gain controls.

Does the woofer move in and out in relation to the movement of the gain control?

The 1501 is very similar to the 81000 but there are important differences. The 1501 is a better amp.

If you turn the gain up and down, does the woofer move in and out in direct relation to the rotation of the gain?

What do you mean by "you only feel current going through subs"?
