20 Most Recent Jensen 100W x 4 Amplifier KA5 Car Audio Amplifier Questions & Answers


Its ought to. Thats what it was really marketed toward with the 2 channels bridged somehow and then put to individual subs in tandem. However, there is no built in crossover. This is a twenty year old amplifier and popular demand had not made it such that built in active crossovers came standard. In that sense its not a great choice for subs. My brother got one and it sounded like a## because he never bothered to add a crossover. Class a/b amps are sooper cheap right now. If moneys no object get a "2000w" amp for about 80 bucks on amazon or whatnot.

When you run a CD the radio needs more current then when you are using only the tuner.

Check that the positive power cable is connected properly and thick enough. Do the same with the ground... I have had this when the ground cable is not connected properly or too thin.

Try grounding it straight to the battery or body with a thicker cable

The yellow wire is constant power or battery and the blue wire is your remote...

The only way I know how to is to send it in and have them fix it. I am in the same boat with my kicker amp. They wont sell the parts by them selves. If they did that they could not charge you a ton of money. Or if you can find someone with the same amp and that is willing to give you the part.

You will have to call Jensen. They normally don't come with amps anymore as most users prefer the RCA input for better clarity and sound quality.

email the maker of the unit and ask for one

I'd be inclined to check to make sure there isn't a short circuit somewhere in the output lines. Maybe a wire is crushed against the car's body or bare wires touching or badly fitted RCA plugs. All of these things could activate the protection circuit. If you have a multimeter it would make life easier but don't forget your speakers will show up as 4 ohms so that's not a short. BMW
