Question about Kenwood Car Audio & Video

1 Answer

I installed a kenwood xr900-5 amp and 2 jl audio 10w1v3-4 subs. When I turn on my hid headlights I get a popping noise for a split second, and also when I lock or unlock the doors I get the same pop. Sometimes it's louder than others. I only get it when the ignition is on and the amp is powered up. any ideas what it is?

You need a better ground or else something isn't grounded.

SOURCE: Audio system makes extra noises... pops

most of the time when a high power amplifier starts making noise not all the time but every once in a while or even all the time its the ground, if the amp turns on its not the power cable. try moving your ground to a different location or try using double grounds. the better the ground the better the sound. and as for turn on pops, put a toggle switch inline on your rem wire and turn it on after the car is started.

SOURCE: most power out of amp w/out blowing subs

you may only be able to get but so much out of the subs. If you turn the bass down a little so the that you dont drive the subs so hard you may get a little more wattage out of them

SOURCE: will a JL audio 1000/1 amp run a orion HCCA 15

Hello evopower,

The JL 1000/1 will power the Orion HCCA OK.

It is stable only to 1.5 ohms so your best choice would be the 15.4 with dual 4ohm voice coils. In parallel, this would offer a 2ohm impedance. The 15.2 could only be wired for either a 1ohm load (too low) or a 4ohm load (less power).

Hope this helps.

SOURCE: jl audio 1000/1 problems

Hello l_miller36,

Depending on how much you paid for the amp on eBay, and how well you like the JL product, it may very well be worth the money to get it fixed. As for the wallet damage, you'll have to ask JL or one of their dealers. But, since the Slash2's routinely sell for over $1,000, I'd estimate the cost to be pretty high.

First, I'd send an email to JL Audio tech support and see if they have a "flat-rate" repair option or if they can give you an estimate of the repair costs. My second option would be to talk to a local car audio shop that does component level repairs. In the first case, you'd get exact replacement parts and whatever warranty JL gives on repairs. Not so with the local option, but it would most likely be less expensive.

Hope this helps, good luck.

SOURCE: JL Audio 500/1 Amp

Do you get sound if you set it on full? If you don't get sound in any way it maybe broked. Do you smell burnt components? Is the protection light on? If so you probably have a shorted transistor inside. If everything looks normal but has no sound at all. The preamp circuit is probably not getting power due to a malfuctioning power supply circuit. The way a car amp works is it has a DC-DC converter, which steps up the 12 volts to two supply voltage. One is usually a -35V, an the other is +35V. To a totall of 70V. Power transistors don't operate efficiently on 12 volts thats why it is designed like that. A PWM (pulse width modulation) circuit which consist of a chip, and various components connected to it drives an array of Power FET(field effect transsitors) usually conected in parallel to add power. These FET drive two or more "powder iron core" transformer. The other side of the transformer is connected to large diodes, providing power to the transsistors that actually drive your speakers. The supply voltage to the section preamp section is usually the same as the battery voltage. This preamp section filter high frequency for things such as low pass, high pass etc, and through many stage of amplification using small transistor, the final stage is the large transistors that drive the speakers. If you can tell me more info I can help you with a step by step guide on fixing the amp.

I have a Kenwood DNX8120 installed in a Jeep Wrangler(4dr). Running a 4 channel JL Audio amp for mids and highs and mono JL audio amp for the single 12" sub. Tried to have the deck tuned by two...


I do not know what sub woofer and speakers you have and how they are installed, don't change the JL Audio amplifiers, they are very good amplifiers. Also amongst others, I have been using Kenwood in my installs for many years and believe them to be one of the top brands for head units. The unit that you have is a good, very good unit, honestly. In a nut shell, the equipment that you mention are all top class and if functioning correctly, should not be the cause of your disappointment. Low quality cables, bad installations or even incorrect tuning, are often the guilty party in cases such as these. You could fill me in on what else you have and what kind of box the sub woofer is in and what car they are installed in? Search for the source of your disappointment somewhere else. dreamsystems.

Shuts off when the volume gets turned up didnt do this wen new


A mono amp usually can handle only two 4 ohm subs. You see when you hook up two subs in parallel it drops the ohms too 2 ohms and 3 in parellal drops it to 1 ohms overheating the amp and cause power failure. Unless you bought a Mono amp thats 1ohm stable. But still I've seen cheap 1 ohm stable amps not last long. Also possible your subs are fried too check them with a multimeter and measure each sub ohms.

Popping sound! please help - jl 500/1 and two jl w3v3 2ohm subs


no connection are good + to + -to - thats all that matters. either the speakers are blown or you need a stronger amp. since you already tried speakers probably need bigger amp. definitley not the box. no such thing as a break in period, are the subs 10 12 inch or what. you could try to bridge them too that means hook both up to the same +-terminals, 2 wires per screw. it usually isnt the way they hook them up, its the wires fuses etc that cause problems. what guage wires is the speaker wire, the power line etc. if you give me these guages i might be able to get somewere

Jl audio 500/1 amp low ohm light at high volume


I would try running the subs in parallel. Pos to Pos Dual Voice, Neg to Neg Dual Voice. Then Run + to + stereo - to - stereo on both channels.
So you have + and - running to one channel and + and - running to the other channel.
Also your LPF filter could be set too high.

This sounds odd, but try putting your subs out of phase from the mains. Just see if it changes anything.

Sub makes loud noise when car is shut off


Does it make noise if the RCAs are unplugged? If not, the RCA shield on your head unit may be burned open.

If the amplifier is set to signal sense, it will take longer for the power light to go off.
