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 .

How should i have my 4ohm single voice coil JL audio 12in subs connected to my kenwood kac-9104d 1800 watt max power (500x1 @4) amplifier?


On the outputs of the amp there is:

+ + - -
1 2 3 4

terminals. Internally in the amp the positives (1 and 2) are connected together and negatives (3 and 4) together. So there is no difference between hooking up in any of the configurations 13, 14, 23 or 2->4. If its a matter of style, probably use the 14 set, since they're furter apart and harder to short out that way, but electrically it doesn't matter.

Be sure the RCA cables are attached and in good condition.
Be sure the remote wire from the deck is hooked up and good.
Be sure the GAIN control is turned up.
Volume on head unit is up. Make sure BASS options are not turned off on deck.
Be sure wires are going the right way. + to + & - to -
Loose wires in the box. Make sure subs are hooked to the terminals inside box.
Check all fuses on amp to determine if 1 or more i blown.

You should check and verify first the output signal in the amplifiers by using a multimeter on the db range, this is to identify good output of the amp. After that check the polarities for correct wire orientations.You should connect the speakers one at a time to check.

KAC-9104D output terminals


This feature allows the amp to be paired to any stereo. The input may be in stereo but the amp then changes it back into mono using sound from both sides. Hope this answers your question.
