I have ajeson 650 watt amp seriees ps2130. the red or green light wont come on ,but the light under the jensen name plate does.

Those capacitors don't add any power they just store power in between bass notes but if you don't have enough current going to it through your power wire and don't have a good ground to bare shiny metal with a wire lug your not going to get a good connection. Also I spray clear coat or rubberized under coating or something over the ground connection so it doesn't corrode in the future and cause you to loose current. If you have the small Jensen 1200 with the lights on it those amp really only put out about 600 true watts. The type of wire your using and fuse sizing makes a big big difference. I used to only use OFC (Oxygen Free Copper) Audio power wire which is pure copper butearnwd about welding cable and it carries much more current and is cheaper and you cab buy it by the foot at ACDCWIREANDSUPPLY.COM so you don't have any extra wire. The shorter a wire is the more current it can carry. Also if you don't have your big 3 done under the hood or know what it is look it up on YouTube. I always run a AGM battery in the back close as possible to my amp and a $20 Stinger Pro adjustable Voltmeter off the amp itself so I can see the amps voltage in real accurate time. Get you a AGM battery, AGM battery, $20 Voltmeter, make good grounds to shiny bare metal. You can get a 10 pk of copper wire lugs online for $10 or less.

No, you cannot use a 270 watt amp kit on a 1000 watt amp. The wattage of the amp kit must be equal to or higher than the wattage of the amp it is being used for.

Sounds to me like the amp is going into protection mode. Try placing one sub on the amp with very little gain. One of the biggest reason why this happens is because the subwoofers are wired wrong. What is the brand and model number for your amp?

check your ground and power wires

I would recommend you purchase a brand name 600watt RMS amp instead of a Jensen 1200 watt peak amp. Trust me you will notice the difference. Try a kicker, hifonics, MTX, audiobahn Autotech... Its not the watts its the quality of the watts..

jensen sucks dude. just sell it and upgrade. red light could be anytihng. chekc your speaker wires and make sure nothing is touching. from the remote start wire(blue) to the amps and subs. chekc and make sure there is nothing touching.

DISCONNECT THE GROUND WIRE. SAND ALL THE PAINT FROM THAT AREA AND REGROUND IT. WHAT I WOULD RECOMMEND IS DRILLING A HOLE THROUGH THAT TRUNK, SAND THE PAINT AWAY FROM WHERE THE GROUND WIRE WILL GO AND BOLT THE GROUND WIRE TO THE TRUNK BOTTOM. THE PAINT WILL CAUSE THE AMP NOT TO GET A SOLID GROUND

Ill go for a better GROUND , sounds like its not grounded properly and thats why the RED LIGHT . DO A RE CHECK on the installation . hope this helps

Disconnect the wire from the remote turn-on terminal of the amp and insulate it so that is can not make contact with anything.

With the wire disconnected, does the amp remain on?

Generally, the power light is green and the protect light is red. If the protect light is on there could be a short in the wiring or there could be an internal fault in the amp.

Disconnect all speaker wires from the speaker terminals of the amp and disconnect signal cables from the amp. If it powers up, the wiring needs to be checked. If it still shuts down (goes into protection), the amp likely has blown output transistors.
