Question about Alpine New KTP-445U 4-channel Power Pack Amplifier
I followed the wiring diagram - as poorly as it is, and connected all my speaker inputs and outputs correctly. I ran the yellow power wire to the battery and the 2 blue/white wires - one from the rear of the amp. and one from the front of the amp. together and connected to a powered accessory wire. I turned the power on and nothing! I connected the speaker outputs to another amp. and they work just fine. I'm not an electronics wizard, but it there some way to accurately determine if teh amp is bad?

Ot two issues, First the AMP is going into a protection mode this means that it is drawing too much current. As netrecov said you need a capacitor, this will oppose the rapid current draw, by allowing the voltage to remain constant. However I would also sugget that you rewire the setup to manufatures specification and make sure that all grounds and supply leads are installed properly. Taking into mind the the 4awg wire has less cross sectional surface than the 2 or 0 AWG wire causing it to have more resistance this is power loss in this case (follow the specifications).
I hope this helps

main problem i think you are having is your loosing power when it kicks a note.. get a power cap! power caps feed your amps constant power! this will solve your problem :)

Use the left and right to connect the positive and negative to the respective speakers in the right and left. Please make sure of the polarity and so be cautious. next you can connect the sub woofer from the left and right channel as the amp is bridgeable. Use the lead to connect from the R- positve to L negative. test and check the phasing of the speakers, must get good low bass or else you can reverse the sub woofer and check again. If you ae having frint speakers connect accordingly the the other channel. Helpful Good day
