Question about Sony XM-754HX Car Audio Amplifier

1 Answer

RCA question Hello, I have a question for you, on the best way to use RCA's from a crossover to a 4 channel amp. I would like to use all 4 channels on this amp. that will power my 4 mids. what I mean is do I use a single RCA from the crossover, and then use Y adapters, so that I can plug into the front and rear inputs on the amp. or do I use the Y adapters at the crossover, and the run 2 RCA's into the amp. Is it better to have 2 RCA cables from the crossover, or just 1. not sure if that makes a difference or not. Thank You!

How many watts is it


http://www.kenwoodusa.com/UserFiles/File/Global/Consumer/Manuals/kac528.pdf

Page 7 of the manual gives you all the different configurations of this amp, and it's MAX power. FYI; Kenwood rates their amps at MAX power, not clean. Hope this helps.

I have a audiobahn a400t and im running 2-12''jh45 mtx jackhammers the speakers are wired in parallel stabel @ 2or1 ohm. the speakers are in a ported box. how do i run my wires to my hook these up right to...


Hello rattle822,

A pair of JH4512-04's can be wired to 2 ohms if the subs themselves are paralleled. There's only one voice coil and it's 4 ohm. If wired in series, the final impedance to the amp would be 8 ohms. They cannot be wired to 1 ohm.

In bridged mode, your 4-channel amp is only stable down to 4 ohms. You can bridge 2 of the channels to provide a relatively low 200 watts RMS X 2. The best power solution for your subs would be to bridge channels 1 and 2 and wire one sub to it. Likewise, bridge channels 3 and 4 and connect the other sub. If you connect both subs in parallel, the impedance will be too low causing the amp to overheat and possible fail.

As for the settings: Low pass filter on, crossover somewhere between 80-100, input levels to match your receiver, and bass boost to your personal preference.

Hope this helps.

Can i bridge the 4 ch. amp to 2 chnl.


Hello bdawson,

Maybe. Some, but not all, 4-channel amps can be bridged. You'll need to provide a specific brand and model number for a more definitive response.

On many bridgeable amps, the connections are shown right on the output terminals, usually the "+" of one channel and the "-" on another channel. The connection diagram in your user manual may also show which channels are bridgeable and the appropriate connections. Some amps may support what they call "tri-mode", powering both full-range speakers and subs at the same time.

Using a multi-channel amp with the channels bridged to power subs is a compromise. While you'll get an increase in power, it usually isn't as much as you would get from a monoblock. And fine tuning for the best sound is more complicated, balancing the filters and crossover so that the correct frequencies are sent to the appropriate speaker.

Hope this helps.

Wiring Speaker to amp


remove all speaker connections to your amp. MAke sure the inputs are driving all 4 channels, and that the built in crossovers on the amp are all set to full range. Conect your full range speaker to each output channel one at a time and verify there is oputput on all 4 channels. If all is ok, then connect your rear speakers to the front(a) outputs of your 4 channel amp, and then use the second 2 channels (rear or B) bridged to drive the sub. Re-configure the crossovers for highpass for front (to drive your rear speakers) and lowpass for sub. This is the proper way to connect a 4 channel amp with a sup whle driving 2 full range speakers.

Spl 620 wn put out loud enough does have sound did i wire it wrong?


Hello ace_sterling,

Not knowing what you have the SPL-620 driving or knowing how you have it wired, it's rather difficult to determine if it's wired "wrong".

I show the SPL DK2-620 as being a 2-channel amp with 150 watts output at 4 ohms, or 180 watts at 2 ohms. Even if the power is somewhat overrated, it should provide more than enough power for a set of standard 2-way or 3-way speakers, or component speakers with a separate crossover.

Powering one or more subs is another thing. You would get sound, but the subs would not be very loud. In bridged mode, the amp is only stable to 4 ohms. So if you are trying to power 2 4-ohm subs, the best connection would be 1 sub connected to each channel. If you are powering only 1 sub, then the bridged connection would be best.

Hope this helps. If it does, please rate as "FixYa".

2 channel amp to 6-6x9 wiring diagram


Hello magoocsl,

Yes, with the use of 2 high-pass and 1 low-pass crossovers, that Kicker amp will operate in what they call stereo and mono simultaneously (SAMS). You'd run 4 of the 6X9's in mono. Wire them in series-parallel with a low-pass crossover on the positive leg to the amp. The amp would see a 4ω load. The other two 6X9's would be wired as stereo, one to each channel with a high-pass crossover. Again, the amp sees a 4ω load.

Here's a link to the appropriate wiring diagram. The diagram is on page 5. Just substitute your 4 6X9's wired in series-parallel where they show the "mono" speaker.

Mac audio mac attack 600, 6 channel amp / subwoofer filter


Hi dougal,
The power cable size depends on how many watts the amp is rated at (realistic) RMS with all channels driven at 20 to 20K.
Buy the largest cable you can afford as you never know when you may add another amp,
Though with 6 channels it should handle almost any reasonable sound system configuration, such as, front, rear fill and the sub/s.
400 watts and less will do fine on 8 gauge wire. 500 watts or more should be using 4 gauge, with a distribution block. The ground should be the same size as the power wire, and solidly connected to BARE metal,
keep it as short as practical.
Use good quality terminal connectors throughout.

The (HI) inputs simply means, using the speaker output from the head unit, as opposed to the RCA connectors.When purchasing the RCA cables don't be fooled by all the fancy high dollar one's, unless cosmetics are important to you.
$5.00 cables will sound just as good as the $25.00 ones. ( The marketing dept. hates that truth. )

You can bridge any two channels as long as they are the matching right and left pair.
Look at the amp, usually the rears are the most powerful and have a low frequency crossover.
The woofer impedance and whether it is single or dual voice coil will determine the speaker wiring.

If the woofer is a single voice coil, 4 ohms...
The positive terminal on the speaker goes to left positive, on the amps left channel terminal. The negative speaker terminal goes to the right channel negative on the amp.

If the woofer has two 4 Ohm voice coils,
Parallel the terminals on the speaker.
Pos. to Pos. and Neg. to Neg. and then wire as explained above it will present a 2 Ohm load to the amplifier, any good amp can handle that. If in doubt check the specs.
I hope i was of some help.
Regards, S.

RCA cable use


You can plug into the left channel and it will feed both the left and right channels.

To confirm that it's feeding both channels, connect the speaker to one channel at a time. With signal fed into the left channel only, you should get sound when you connect the speaker to either channel.

2 channels not working on 4 channel amp


Well firstly are you using a parametric crossover with your radio and how much rca cables do you have coming you head unit (car radio) if you going to bridge the front up with you rear speakers u wont be able 2 hear the rear speakers try hookinking it up 2 your head unit's front speaker output and have ur rca cable connected to your amp running on your rear output of your head unit by doing this you can use your fader on your head unit to control your front and rear speakers
