Hi.
I'm new here.
I bought a sound system a few days ago and got it installed yesterday.

The parts I got were:
Speakers: 1 pair Clarion SRQ1631R (front), 1 pair Clarion SRG1321R (rear)
Subwoofer: 1x Fusion CS-SW120 1000w
Amplifier: 4 channel Clarion XR2410, 2 channel Clarion XR2210.
Headunit: JVC KD-R526
I also needed a fascia panel to put in the head unit.

I have the 4 speakers connected to the 4 channel amp and the sub connected to the 2 channel amp. The 4 channel amp has a high pass filter enabled and the 2 channel amp has a low pass filter enabled.
My question is: on the headunit, there is also a high pass filter. Do I need to touch that?
Thanks for your help guys.
Please don't blast my budget system

 

Enable the high pass filter on the head unit only if you want highs/mids through the 4 speakers (no bass). I enabled it on my setup so that the subs provide the lows only.

 

Thanks for the reply.

If I have the hpf enabled on headunit, the output volume of the subwoofer is really low.

If the hpf is enabled on the amplifier itself, wouldn't that be enough already?

Edit: When I didn't have the hpf enabled on the head unit, the bass was very powerful and heard quite easily.

 

you heard the bass better because it was being pushed through all speakers.

turn the HPF on, if you have the choice set it to either 50hz or 63hz depending on the music you listen to. Then set the amp to the same setting and turn the power (gain) up a little at a time until you find the volumn you like from the sub. this will in turn give you a much better sounding system and extend the life on your components.

 

Thanks for your reply. I am new to this and because of this, I had a shop install this system for me. I also called them and the guy told me not to worry about the headunit hpf as the amplifier hpf already does the job.

Another question is: the bass boost is set to +6db. What happens if I set it to +12db?

 

If your drivers are properly crossed over on the amplifiers (HPF, like you are saying, if I am reading you correctly), enabling an additional filter on the headunit will do nothing but further choke down the frequencies (possibly not at all, depending on where they overlap)

Some people do entirely electronic crossover systems through HUs and what not - not a bad choice depending on your setup.

 

bass boost will cause distortion depending on your amp. so to turn it up will cause more of a chance to distort bass.

IMO i use the HU HPF and match it to the amp's. so like i said earlier set the HU to 50 or 63hz and match the amp to that.if you listen to rap and stuff set it to 50, if you listen to rock/punk or anything else with a lot of mid bass set it to 63hz.

if you have a good amp, turning the bass boost up will do exactly that....add more bass.

this is a very simplified breakdown of all this, so disclaimer before everyone tries to chime in.

 

I think the head unit he has only has two pre-out outputs. So, if you put the HPF on, it will cancel out any bass going to his subwoofer amp - which is what he is describing. Turn the HPF off on the head unit and just use the crossovers on the amps.

 

I listen mainly to trance and sometimes rnb.
I'm unsure what you mean by set the HU to __hz. From what I can see on my headunit settings, I can turn the hpf on/off, subwoofer lpf 55hz/85hz/120hz.
So on which amplifier do I set the crossover frequency and which amplifier do I set the gain?

Thanks for all your help guys.

 

+1, the tech specs for that model states "2 RCA Pre-Out Terminals (Front + Rear/Subwoofer Switchable)". Not at all ideal for a 6ch setup, but..

If you're actually getting sound out of all front/rear/sub channels.. set the JVC's "L/O" MODE" to "REAR" and then set "HPF" to "OFF". Use the crossovers that are built into each amp.

You might be able to use the JVC's built in sub level adjustment and crossovers.. but it may or may not work, depending on how your shop wired everything up to get 6 channels out of 4. I'm guessing your front/rear fader on the JVC might not work exactly as intended either.

 

At this point, the best thing to do if you have any more questions is to go back to your installer and have them troubleshoot your situation. There isn't much more we can do over the interwebz.

 

Thanks guys.

In the end, I turned off the hpf on the head unit and switched the L/O mode from subwoofer to Rear.

 

Make sure you have the subwoofer RCAs hooked to the correct outputs. That headunit has 4 preouts. Two for the front and two for the rear/subwoofer.

You didn't say how you had the 4 channel amp hooked up. The best bet would be to have the front RCAs outputs run back and use that to drive all channels of the 4 channel amp (y-splitters may be needed?). Control your fading by the gain adjustment. Then run the rear/subwoofer to the 2-channel amp.

Now, if you use the headunit high pass filter, you do not use the ones on the amplifiers. The same for vice versa. Most likely the best sound will come from running the amps on full range and using the head unit crossover and PEQ to adjust sound. Good luck.

 

I actually don't know how the 4 channel amp is set up. All I know is that the 4 channel amp is used for the 4 speakers and the 2 channel amp is used for the subwoofer.

The setup at the moment is: jvc HPF turned off, L/O mode set to REAR, 4 channel amp hpf enabled, 2 channel amp lpf enabled.
I have to say though, when the jvc HPF is enabled, the sound is a lot more crisp, but less bass.

 

Try turning the JVC high-pass off again, and if it's somewhat accessible, use a screwdriver to raise both the Clarion 4ch's crossovers just a little by turning clockwise.

You might be able to find something inbetween that has more clarity up top, and still a little punch down low from your main speakers. Also, it might be easier to turn off your sub while doing this, and then back on to fine tune.
