Question about Jensen A600HLX Car Audio Amplifier

3 Answers


The amp has 2, 3, and 4 channel modes, but I was wondering if it's possible to connect only 1 subwoofer. The head unit provides plenty of power for the other speakers so I don't wish to connect them. If I were to use this amp, would it be best to put it on 2 channel mode and bridge the 2 channels to the sub? My sub is a pioneer 12" 150W RMS and 800W max, does anyone know how much power would go to sub if I used the method I mentioned? I don't want to damage the sub. What is the RMS power? I hope someone can help me figure this out because I can't wait to install this!

I have this amp, and I bridge the rear channel to my sub, and it must be sending the full 600 watts to the one channel, because so far I have managed to blow 3 subwoofers rated for a max of 800. (One Kicker and two Acoustic Audio's) I have everything tuned as it should be, but I think my main problem here is just not using quality subwoofers, rated at about 600 RMS instead of 800 max.

DON"T DO IT! It will kill you amp or st lesadt the ONE channel you choose to use. The only way you can use ONE Sub is to use a Dual Voice Coil and hook each channel to each voice coil.

I can't find any documentation for your amp; it was made when Jensen was owned by Recoton, and they're no longer in business. With any 4-channel amp, you can't bridge all four channels into a single channel. What you can do, if you're connecting it to a single sub, is to bridge two of the channels into one channel and leave the other two channels unused. It doesn't usually matter which two channels you pick, but some 4-channel amps designate channels 3 and 4 (or rear channels) for the subwoofer. Whichever ones you use should have a "LPF" or "LP" crossover setting available.

Hooking sub up

Hello missywarden,

According to the specifications, the amp is capable of "tri-mode" operation, that is, running normal speakers on the individual channels while also powering a subwoofer in bridged mode.

Your sub needs to be a minimum of 4ohms and should be relatively efficient. I'd look for a sub that has an RMS power range of from about 75 watts up to a maximum of 250 watts.

The sub connects to the leftmost speaker terminal (positive - right channel) and the rightmost speaker terminal (negative - left channel).

It's not going to be a really loud subwoofer. The power is 360 watts RMS which will be shared by the normal speakers and subwoofer.

Hope this helps.

Ok . i have a pair of crossfire subwoofers, @

Your amplifier is 4 channel... and only 2 ohm stereo capable.

You will get the most power putting 1 subwoofer wired in parallel on each BRIDGED channel.

This will give you a 2 ohm stereo load.

Both + on 1 subwoofer to + terminal on amplifier bridged channel 1
Both - on 1 subwoofer to - terminal on amplifier bridged channel 1

Both + on 1 subwoofer to + terminal on amplifier bridged channel 2
Both - on 1 subwoofer to - terminal on amplifier bridged channel 2

4 chanel amp I dont know how to conected,to radioand one subwoofer

Hello canelo63,

Your question appears under the product listing for the Dual XPA4100 but the in the text you say the amp is actually a Jensen, so it's not possible to provide specific connection information.

But most bridgeable amps can be connected to a single subwoofer and the other two channels used to drive a set of regular speakers. I'd connect the front speakers to channels 1 and 2 and wire the subwoofer to the bridge connections of channels 3 and 4. On the XPA4100, the bridge terminals are the first (negative) terminal on channel 4 and the last (positive) terminal on channel 3.

Hope this helps.

I wish to know the correct way to connect a Schneider 800w amp Model:spa-9705. What I have is a lead from my deck(marked sub woofer - 1 x red & 1 x black) but at the back of the amp in question it has 4 x...

Hello i_starlin606,

The Schneider SPA-9705 is a 4-channel bridgeable amp. How you intend to use it and what speaker(s) or subwoofer(s) you are connecting to it will determine the appropriate hookup.

If used to drive 4 sets of normal speakers, you would connect your front channels to one set of inputs (usually 1 and 2) and the rear channels to the other set. You would not use the subwoofer outputs coming from the deck.

If used to drive subwoofer(s), you would need two "Y" adapters with a female input side and 2 male outputs. The cables marked "subwoofer" would be plugged into the female "Y" and the male ends would be plugged into the 4 channel inputs on the amp (paired as 1-2 and 3-4). The front and rear preamp outputs on the deck would not be used.

Speaker/subwoofer connections will depend of the number of individual speakers or subs, whether they have single or dual voice coils, and the impedances of the voice coils.

Hope this helps.

Hello herb31,

It sounds like there is a difference in the signal levels on the inputs to the amps. You did not specify what the RCA's are connected to on the head unit side. If they are connected to a stereo pair of preamp outputs, you may be able to solve the problem by using only the channel with the higher signal and use an RCA "Y" adapter to split it to both amps. If they are connected to a dedicated subwoofer output on the head unit, make sure that the head unit is set for "subwoofer". Some less expensive head units, I know JVC in particular, has only 1 set of line outputs and requires you to go into their "PSM" (Preferred Setting Mode) to set the line output mode and if you select "subwoofer", then allows you to select the low pass frequency.

If you are converting speaker-level outputs through a "line out converter", check both the input and output levels.

Also, if you are splitting an output from the head unit, you still need to connect 2 RCA's to the amp inputs. The signal will be properly split if you use a 1-female to 2-male "Y" adapter. To feed the same signal to both amps, you would need 3 "Y" adapters. Feed the output signal to the female end of the first "Y", and plug the male ends into the other 2 "Y" adapters. Then, the 4 plugs you have left on the ends go into your amp inputs.

Hope this helps.

Amplifier loads

Hello ronnieyannon,
A single 4 ohm speaker wired to each channel, like you have them wired, presents a 4 ohm load. And it appears that you have them connected properly. The 401s is only stable to 4 ohms when bridged, so if you were to parallel the 2 4 ohm subs in bridged mode, the load would be 2 ohms and the amp would most likely overheat and go into protection.

I'd wire them the way you have them wired.

Each channel of the amp outputs only 100 watts into 4 ohms. That is adequate for regular full-range speakers, component speakers, mid-range drivers, and even some small subs. But it is a little low on power for most subwoofer applications.

Hope this helps.

Hello, I have a 2000 VW passat with a Monsoon radio system. How do you install a new head unit and speakers while maintaining the factory amp? If this is impossible, Can I use the current speaker wires...

Hello ctr1russo,
While it's not impossible to install a new head unit and speakers and leave the factory amp, it'll be a real bear of an install.
In order to work, the Monsoon amp needs 6v which is provided on the speaker leads. An aftermarket head unit will not provide that. Best to just install a new amp.
You should be able to use the wiring, including the speaker wiring, with no problems.
Check out for the appropriate adapters and wiring harness for Monsoon equipped vehicles. Just enter your vehicle info and it should bring up the required adapters and harnesses to make everything work properly.
There are three ways to connect more than one speaker to a single channel: 1) Parallel - both speaker +'s and -'s wired together - load impedance will be halved (2 4-ohm speakers in parallel equal a 2-ohm load). 2) Series - The + of one speaker wired to the - on the other speaker and the remaining + and - going to the channel output - load impedance will be doubled (2 4-ohm speakers wired in series equal an 8-ohm load). 3) Using a crossover - connect the bass speaker (woofer) and the input of a high-pass filter directly to the channel output and the treble (tweeter) speaker to the output side of the filter. In any of these connections, you want to make sure that the load (ohms) your amp "sees" is not less than it is rated for. Most amps will work into a 4-ohm or a 2-ohm load with no problems. Going below 2-ohms is bad, because it will cause the amp to overheat and possible fail. Going above 4-ohms is no problem for the amp, but it won't produce as much power (watts) at the higher impedance and your speakers will not be as loud as they could be.
Hope this helps. If it does, please rate as "FixYa:. Thanks!

My head unit has 1 set of preamp outputs can i conn. 4 speakers

Yes you can use a y to go to all four. Or you could bridge the four speakers wires onto the two outputs for 1 channel

I found this amp and I can't seem to figure out what the wattage is?

You are probably aware on how to use these output figures, but I'll write a quick explanation on the specifications for future readers anyways :)

The concpet CC-452 amplifier has the following power output specifications:

Calculated at 14.5 volts DC;

At 4 ohms per channel - 45 watts x 2 (RMS)
At 2 ohms per channel - 70 watts x 2 (RMS)
At 4 ohms bridged - 150 watts x 1 (RMS)

This means that your amplifier would provide 45 watts of power each for your front speakers, which are normally a 4 ohm load per side (45 watts for left, 45 watts for right), that's unless they are one of those exotic higher end brands (eg: Boston Z6s which are 3 ohms). Rarely, you will find speakers that are rated at 2 ohms per side, but in this instance the amplifier will provide 70 watts of power into each speaker. On your speaker specifications, you will find a value termed "nominal impedance" which will give you the ohm rating of the speakers being used..

On the other hand, if you "bridge" both channels into a single channel (using a diagram often marked on the speaker terminals of the amp), you could then provide 150 watts into a subwoofer (providing it was a 4 ohm woofer).

It's not recommended to use this amp bridged under 4 ohms..

Some subwoofers may be lower than 4 ohms, and you will not be able to use this amplifier for these types of speakers without risking amplifier failure. Also, some subwoofers may have 2 seperate voice coils, and you will have to use both channels of the amplifier seperately (not bridged) in order to correctly connect this type of speaker for use.

Amp connection

Parallel would be the best way to wire them. 2 4 ohms subs to one channel wired parallel would be a 2 ohm load for that channel and if u wire them series then 2 4ohm subs to one channel would be an 8 ohm load for that channel.
