It does have a high pass, low pass and through switch that I have set to through. Along with punch gains that I have turned down. The adjustable crossover appear to be used only when the filter switches are set to lpf.

I gave up and got another amp. Seems like the new amp holds up. It's an old rockford fosgate punch 800a4. I ran it hard for an hour and it just kept going. Will need to do some research though as it sounds a bit muddy compared to the other two amps. The MA was almost too bright on the highs...

I was under the impression that RMS wattage was what an amp could sustain and peak wattage was what your kind of explaining. Seems that typical RMS ratings are half of peak. With that in mind, an amp rated at 100W RMS should not put out a constant of 65, to me, that's failure. Thanks for the...

Were they ever making rated power? Talk about being slighted...100 x 4 really means 65 x 4... 35% failure? Would explain why mine pushes the speAkers fine for a little while. Obviously if I had known before hand... I'd have bought something else. I hope the used old school RF 800a4 works that...

Well... not sure what the deal is with the NX4, but honestly, bridged or 4 channel sounds almost the same in volume to me. In bridged mode, it overheats and shuts down faster. So... the money on that amp appears to have been a waste already. The kenwood however, did push the fronts bridged far...

For now, I adjusted the gains by ear. Turned my HU up to 75%, played the 100hz, 1000hz audio and adjusted from low to high until I heard distortion/clipping with either frequency, then backed the gains down a hair. Now... it just isn't loud enough to suit me. But I know if I push the amp much...

I've read that a lot of guys do that with the front sound stage. Personally I like the sound all around me and with 6x9's in the rear deck, I at least get a bit of benefit out of the trunk for bass that isn't shallow sounding. I run the rears down to a lower frequency than the fronts as well to...

Not to sound like an idiot... but then why have 35? If the HU clips at 30 then why can it go to 35? Pretty sure that just made me sound like an idiot though... I didn't really "set" my gains. When I installed it, I put them at about 40% on the dial (hard to say since there are no numbers or...

I just bought and installed a NX4 (100w RMS x 4 @ 4 ohm)amplifier in my car to replace a Kenwood KAC-8452 (70A RMS x 4 @ 4ohm) I was running. When run relatively hard/loud, it seems to heat up and the protect light comes on. I tried to match my speakers with an amp that was at least as high...

I know this is an older thread, but I thought I'd ask if you still have the NX4 and if so, how is it holding up? Hopefully it's doing well... Just bought one off ebay to power some polk 6x9's and 5x8's.

Also is not the HU... I disconnected the HU today and connected a mp3 player to my amp using splitters so I could drive all 4 channels. After about 15 minutes, the volume drop happened again repeatedly just like the HU did. So, since my issues first presented with only the HU and speakers (no...

Well, wasn't a bad power connection at the amp... volume still drops on it's own.

I'm wondering if your speaker wiring is out of phase. +/- do matter, but from personal experience, polarity is only relative to polarity of the other speakers. Since yours seems to sound better faded towards front or rear, that suggests your front is out of phase with your rear. When I installed...

I have adjusted them since my first post. they are now around 50% and after about 30 minutes of running around 31 on the hu, the volume still drops about 25%. at first, the volume fluctuates up/down, then about a minute later, it drops 25% or so and stays there. Then if I turn the hu to max...

I have adjusted my amp gain to be just high enough to not distort with the HU volume at 30. It will run about 30 minutes like this, then the automatic volume drop happens again. I'm going to try and pull teh HU out and wire in a typical mp3 player using RCA Y cables so I can run all 4 channels...
