Question about Kenwood KAC-9104D Car Audio Amplifier

KAC-9104D output terminals

I have a kenwood kac-9104D monoblock amplifier. it has 2 positive and two negative output terminals. i have seen this any many mono amplifiers and have always wondered if using 2 of them or all 4 for the same speakers is different. does using just 2 bridge the subs. example: i have to dual 4 ohm voice coil kicker CVRs. if i run wires from each sub to each set of output terminals, is that the same as putting the wires from both subs into 2 of the terminals. i know on a 2 or 4 channel this would bridge the amp, but on a mono what does it do?

    thats what i thought. it just didnt make sense when i hooked up some subs. i normally run 2 dual 4 voice coil kicker CVRs on the amp at one ohm, each speakers wire into each terminal. its one ohm stable. i hooked up a set of the SAME SPEAKERS in a different box but the wires are tied together in the box so both speakers were hooked into two wires. its still run at 1 ohm but i only used two terminals and after about 2 minutes the amp went into protect.

    thats what i thought but i have 2 kicker CVRs run at one ohm (amp is one ohm stable) each set of wires into each terminal. so one wire per terminal. i put the same model speakers (same dual 4 voice coil) but in a different box in, but the wires were tied together in the box. still ran at one ohm tho. but since the speakers were tied together in the box i only had one set of wires coming out the box. i put them into one positive and one negative terminal and after a minute or so the amp went into protect.. it puzzles me ha

Ok i have the same amp and 1 2ohm dvc sub and was woundering the same thing but from futher research and askin sum xsperts. What i found out is that it is only one channel and even tho there are 2 (+) and 2(-) they actually connect inside the amp makein it one . so if u wanted to wire sumthing parralel u wouldnt have to hook wires from one coil to the other on the speaker , u can just hook it up to the amp. so basically both +'s and negatives on the amp are actually one within it so all the power if you only use one set of them and if u wanna add more subs its just easier to add to the amp by using the xtras .

Bridging two12" subs and one 15" sub to my Rockford fosgate T 1500bd amp


assuming all 3 subs are 3-4 ohms, running all 3 in parallel (the 3 positive leads all attach to the amp positive terminal, and all 3 speaker negative leads connect to the amp negative terminal) will bring you at or above 1 ohm, which the amp is capable of handling. With 1500 watts, you will want to use 8 gague power leads for the amp, 12 gague speaker cables, and an inline 120 amp fuse between the amp and the battery, within 1 foot of the battery.

With the Uniden UH7700NB How do I tell which is positive and negative on the power input THANK YOU


You can connect the radio to any standard 12 volt DC power source, with either a positive or negative ground. If you don't know whether your power supply uses a positive or negative ground, consult the manual for your power supply or contact the manufacturer.

So how do wire this set set up to a bridged amp any help would be appreciated


assuming that is a dvc dual 4 ohm speaker, and you have a 2 ohm bridged amp, you run a positive from each side of the speaker into the bridged positive of the power amp, and run a negative from each side of the speaker into the negative bridged terminal of the amp. if, indeed, you have 2 4 ohm voice coils, running them bridged in parallel wiring will bring the load to 2 ohms. if you have 4 voice coils, of 4 ohms apiece, you could run all 4 parallel into the amp, but that would bring the load down to 1 ohm, and you would have to make sure you8r amp can support 1 ohm operation.

I have a boss 400w riot 2-4 channels,how do i connect the high level wires? Because stereo doesn't have rca's


to use the high level leads, you have to isolate the wires going to each speaker (if using 4 channel mode) or isolate the wires going just to the rear if you are using 2 channel mode. you have to strip a small piece of the insulation off each speaker wire, and run it into the amps high level input harness. if you dont have the high level input harness, you can get a 2 channel high level to rca adapter for around $20. basically, you are tapping into the signal to the stock speakers to feed music to the amp. make sure you get all your positives and negatives correct. brighter wires are usually positive; however you may be faced with sa speaker which uses a grey wire, and another grey wire- the second with a black line. you will have to, again, turn to internet research to determine which is positive and negative, if the colors are not obvious.

Bluetooth LG to my Kenwood


you need to make sure both the Kenwood and the LG have bluetooth enabled. Then you pair the two using the pairing function in the LG. Hopefully this should enable you to play music from LG on Kenwood and also receive calls. As you have not provided any model numbers it is difficult to say whether the phone and your Kenwood audio systems are compatible.

Best to go to this website and select the correct model numbers and find out which features in your LG phone will work with your kenwood.

Take of your positive battery cable. This should erase all your memory, since the car has no more power.

Replace the blown/shorted amplifier output Mosfets that are causing it, and it will then be happy to reset itself :)

RCA CABLES


RCA cables are the best way to get the audio from your head unit to the amp. If your head unit doesn't have RCA outputs, you might be able to use the speaker outputs of the head unit to connect to the "high power" or "high level" inputs of the amp, if the amp has such inputs (check your manual).
