Yellow mouth Posted February 24, 2016 Report Share Posted February 24, 2016 Trying to hunt down a good used JL 400/4 amp if anyone is looking to upgrade. Saw one on here awhile back and figured I'd give it a shot. It will be powering 4 JL MX7.7 speakers. Thanks Link to comment Share on other sites More sharing options...
Miss Jazzy Posted February 24, 2016 Report Share Posted February 24, 2016 I bought that one. Keep an eye on ebay they pop up on there a lot. Link to comment Share on other sites More sharing options...

buttapollock101 Posted February 25, 2016 Report Share Posted February 25, 2016 I've got one considering my options for upgrading amps or just buying a second. Link to comment Share on other sites More sharing options...
HarleyG8r Posted February 25, 2016 Report Share Posted February 25, 2016 Reburbs here from an authorized JL dealer, probably for about the price of a used one. http://creativeaudio.net/jl-audio-refurbished-m400-4-4-ch-cl***-d-full-range-marine-amplifier-400-w/ Link to comment Share on other sites More sharing options...
Island Style Posted February 25, 2016 Report Share Posted February 25, 2016 I do have a400/4 JL Amp. I just dropped off at the dealer and they are sending me a new one. I will keep you posed. thanks JD Link to comment Share on other sites More sharing options...
Yellow mouth Posted February 26, 2016 Author Report Share Posted February 26, 2016 Thanks for the feedback. I am currently running my 4 mx7.7's off of the Simrad Sonic Hub and I think it puts out 200 watts total which should be 50 per channel (doubt it). I'm really pleased with the system until turned way up while running (which is the only time I play it loud) and at that time it starts to distort slightly. My stereo guy doesn't think it will make much of a difference, but I think it definitely wouldn't hurt. If it would get a true 100 watts to each speaker it hopefully will solve my small problem. Love the JL's... Everyone that may have one for sale please keep me posted..... Link to comment Share on other sites More sharing options...

Yellow mouth Posted March 4, 2016 Author Report Share Posted March 4, 2016 Thanks guys for the heads up. I would like to get one from someone here on the forum if I can, but if I can't I don't have a problem reaching out. On a side note, has anyone ever run their system off of a sonic hub and then added an amp?? I'm just wondering if I will see any change in performance going from the 200 watt sonic hub to a 400 watt amp? Appreciate it Link to comment Share on other sites More sharing options...
Yellow mouth Posted March 20, 2016 Author Report Share Posted March 20, 2016 Island Style, just checking to see if you ever got your new 400/4 back and if you wanted to get rid of it by any chance. I'm still in the market, so let me know if you can... Thanks Link to comment Share on other sites More sharing options...
Island Style Posted March 22, 2016 Report Share Posted March 22, 2016 YM, I spoke to them today they said turn around time is 4-6 weeks. The unit went in on 03-02-16 Link to comment Share on other sites More sharing options...
Yellow mouth Posted March 22, 2016 Author Report Share Posted March 22, 2016 Thanks for the update. I'd be interested when you get her back if I hadn't found one yet. Keep me in the loop. Link to comment Share on other sites More sharing options...
A1amarine Posted March 23, 2016 Report Share Posted March 23, 2016 I have a MHD 600/4 which is JL Audio's top of the line amp available. It's retail is over $900 and i'm looking for $550 shipped. It's less than a year old. I am changing up to a 900/5 so I can add a subwoofer. I am currently powering four 8.8's in my Jupiter. Link to comment Share on other sites More sharing options...
Yellow mouth Posted March 25, 2016 Author Report Share Posted March 25, 2016 Thanks A1. I am only running 4 MX 7.7's and don't know if they can handle the 600. Let me do some checking... Link to comment Share on other sites More sharing options...
A1amarine Posted March 26, 2016 Report Share Posted March 26, 2016 If you were running the M series i would say your perfect but the MX series really cals for the 400/4 Link to comment Share on other sites More sharing options...
Yellow mouth Posted March 29, 2016 Author Report Share Posted March 29, 2016 Thanks A1, I came to the same conclusion. The 400/4 would be perfect. Keep an ear out... Link to comment Share on other sites More sharing options...

Is it pretty good to go? Im am debating the same setup, just not sure I'll need a sub or not. Link to comment Share on other sites More sharing options...
