Post the voltage on all of the pins for the ka7500 driver IC. Look up the datasheet for the TL494 (link below) if you don't know the pin numbering scheme.

I want to connect a kenwood how to connect a kenwood KAC-81050 car amp to a house system can it be done?


Yes it can be done. This doesnt mean that it should be done. First thing is finding a power supply to supply power to the unit. you would need to find the size of the fuses on the amp and finf a power supply to feed that power. All home theater systems have built in amps on them. It would be much simpler to find a home theater system to fit your need. However if you insist on this setup remember to find proper power supplies and wire the system with the proper gauge wire for the amp draw. No sense in burning down the house over it.

Can i use my jensen jxp340 amp with my one 800watt 12" 4 ohm subwoofer?


Yes, technically you can, however you will be putting both your sub and your amp at risk. One of the worst things you can do to a sub is underpower it. The easiest way to explain it is n ot giving enough power to the sub leaves it starving for power. The motor structure ends up working too hard to try and move the cone properly and what happens is the sub will usually seize up rather than blowing out in the term you usually hear (ie, I had my system cranked up and I blew my subwoofer).

Secondly, in an attempt to get any real sound out of the under powered sub, you'll probably end up cranking the gain and bass boost on the amp which ends up overworking the amplifier quite a bit and can in turn lead to fried out amp chips, burnt up circuit boards etc.

Thirdly, by maxing the gain bass boost you're going to end sending a lot of distortion through your subwoofer in an attempt to get some decent bass. Distortion kills both subwoofers and speakers alike.

So to answer your question, yes you can hook up your subwoofer to that amp and yes, it will probably play for a while but I wouldn't recommend it. Look for a class d or mono block amp to push your sub as these will give you the most power and best heat dissipation. They are designed to push subwoofers specifically and you will get better sound and longer life out of your equipment. A good rule of thumb is look for an amp within 100-150 watts of both your RMS power handling and your Peak power. Remember, when it doubt, always go a little bigger on the amp side of the spectrum. It's easy to "tune down" an amp by having the gain and bass boost at a lower level (50%, 25% etc), than to turn 'em all the way up just to get some bass and end up prematurely blowing out your sub, amp or even worse, both.

Amp is getting power but its not playing


Checking wires doesn"t help unless you are checking them with a multi-meter. Amp needs 4 things to turn on. 1) 12volt power from battery, 2) 12 volt power from radio (remote turn on), 3) ground (solid ground to the chassis or the car free from paint or rust), 4) fuses on side of amp need to be good. If any of these 4 things don't measure up then fix them so they do. If all 4 are verified with the meter and still no lights then you might have a dead amp. If the lights are on but no sound, then there are many other things that needs to be checked.

One channal does not work


swap your RCA's input to the amp. Does the channel that works switch to the other side? If so, then the problem is either your rca wire, or in your source unit. (try the wire first). If the same channel still is out, then problem in the amplifier or speakers. Move to swaping the speaker wires, right to left, and left to right... If problem same, then trouble is AMP, if problem moved, then trouble is speaker. If amp, remove amp, troubleshoot amp... (there are 3 basic parts to any amp... Power supply, input section, and amplifier section...) You know it's not the power supply because the sound is good on at least one channel, and most alll amps use one power supply for all channels, so if one channel sounds good, then you can rule out the power supply. Second, when an amplifier fails (usually, 90% of the time or more) it will result in a shorted output transistor or some other nasty condition that will blow a fuse, or toast a supply almost instantly, and again, your amp powers up, so odds are that the amplifier section of the amp might be ok. (no guarantee here, it's just the odds...I'd say it's like a 40/60 thing.... This leaves you to focus on the input section. First rule out the simple things... bad wiring, (rca, or speaker), bad speaker, bad source. Then rule out the simple things at the amp... broken rca input connectors (inside the amp at the PCB where the solder is) or outside the amp, where the jacks may have been crushed. Then rule out broken speaker terminals, where they can be cracked inside at the board where the solder is in the same way. After all this, you need your amp serviced by a qualified tech.

Installing The Subwoofers to the amp... etc.


You should go with a 4 guage power wire kit. If your amp is going in and out
at high volume than that is your problem. 8 guage will work but, if you want
the proper current which is your power from your battery, going to your amp
than I would recomend the 4 guage amp install kit or just the main power
wire coming from your battery. If you would like contact me and I will send you
to a very good sight with all the info you will ever need for car amplifire installation.

Powers on but no sound


Check the main amp fuse under the hood, even if it looks good just change it. Often times that light on the amp can come on just from the power amp tunon wire. Try a friends subwoofer box just to make sure the connectors on your box are good, and if that doesn't work then give me some more details....year/make/model of car, what kind of sub, what types of things do you see on the side of the amp....is there a green light as well as a red light?

NEW AMPLIFIER WILL NOT LIGHT UP OR POWER UP


It sounds like your saying that you have two identical amp, that both are on the same power wires and remote wires and sam grounds? Well if thats the case then you did ok as One amp sounds like its blown. First tghing is check the main fuse. If its good and the unit still dosent resond then the power supply in the amp is blown as theres a switching supply that increases the 12 volts to get power to drive the Mosfet output devices. Was it ever working?? yes then the amp needs service. Do you know how to work on solid state elctronics down to componet level?? No?? Ok contact these folks at the addy im posting for you or take the amp to your local servicer. Good Luck. AudioSupport@VisonikCarAudio.com

Legacy la590 amplifier


Ok If the power wire as well as the remote wiring was checked then you know the problem has to lie within the amp?? Yes it does. Do you know how to check b+ lines with a vom?? as well as use a schematic to trace one curcuit to another?? If not its best in my mind to have a pro look at the amp but if you really wanna try to see if theres something burnt in side by all means open it up look around and if you dont see anything out of normal such as burnt things crispy parts or fried wire then its time to unistall the amp and take it to your local repair depot. Now your local repair person may or may not be a sspecialist in auto amps?? If not My advice would be to ship your unit directly to the manufacturer for repairs. First thing you wanna do is look in the owners manual under troubleshooting . it will tell you where to call and if a RMA is needed(RMA means Return Materials authorization).Or contact the company at 1-425-788-0932 or online at support@millenniaCorp.com Good Luck
