I have a massive audio N4 running at 2.6 ohms pushing my 3 Alpine 8inch Type R's. My subs are seeing close to 1000 watts and the amp barely gets warm. If I'm not mistaken, that's probably the same amount of power you want to send to your JL sub to wake it up.
I just switched from a JL HD/900 and wasn't all that impressed. Plus, it seemed to heat up a lot quicker than the N4. Lastly the massive amps have a small foot print and cost less. You may want to give them a look: Massive Audio*::*Amplifiers*::*N4 - Mono Block Amplifier

1000W@2ohms RMS
On JL's webpage its telling anything over 600W RMS can blow it. I bet you know more them me on audio things but I'm a bit hesitant. ![]() Last edited by 2011 Nismo#91; 09-01-2011 at 05:54 PM. |

I am not excluding myself in this pitfall; You get used to your system and then after a while it just doesnt seem as loud. It exactly the same as getting used to the power of your car, you want more power so you mod it. Then you then start tweaking and playing with your system and before you know it your pushing the limits of your equipment. Simply stated, It is purely human nature to want more. and especially more for less, or better yet, free! Thats why I am more on the conservative side of the fence.

Just use your gain knob and adjust it down plus you will never see 1000 unless your head unit is at full tilt with the amp at full gain. "depending on the amp as well"

I prefer the alpine amps. Great bang for the buck, my vote goes for the pdx.

I have a JL HD900 amplifier driving my 13TW5 at 500 watts RMS and it rocks! Make sure your enclosure is sealed VERY well. The slightest air leak will dramatically reduce output and sound quality. When I first got it, It was ok but not what I was hoping for. I took my box out and I was inspecting the driver and pushing on it and I could hear air excaping. I sealed inside and all of the outside edges and seams with fiberglass. Back together and cone test. Ahh Sealed! I started playing it and I was floored! Not only was the bass crushingly low but the sub was crisp and tight. It sounded great! I am now adding some more insulation behind the panels and area around the box.
Long story short - 500W will do the job. I would not push this sub much past that, especially a JL HD amp. Any more power would simply exceed its mechanical limits. This sub is very loud! and it kicks like a mule!

I find that JL AUDIO XD600/1 is a perfect match for the 13tw5.

I do not like JL simply for the fact of how they come off as thinking they are the best out there because of how much they charge for their products. I mean even their stealth boxes are insanely over priced.

![]() However, I guarantee that your sub is not seeing 500 watts. It's maybe seeing 350 watts, tops. You have to remember that there are 4 additional channels being driven within the HD900. That has an impact on the amps ability to drive the sub channel. Also, as bigaudiofanat has stated, you'd have to adjust the gain on the amp and head unit to full tilt just to see that amount of power. At that point, the sound would more than likely distort and you'd probably end up damaging your speakers. Like I said, I had the same amp as you. It was pushing JL separates (tweeters/mid bass) and two JL 8w3's in a sealed enclosure. Everything was processed through my Audison bit one. On many occasions, the amp would become exhausted and loose its musicality which resulted in a degradation of sound. If you play your music at reference levels (I believe most of us do), you will exhaust the power reserves of the HD900. That was my experience; however yours seems to be different. To the OP - Per your post, you’re trying to decide between the Alpine M6 and the JL HD750. If you want to save some cash, go with the Alpine. I think that’s a smart move and is a good amp. By the way, what are you using to drive your front speakers?

Rest assured that JL Audio amp was designed to run 900 watts rms within grueling tolerances at a bare minimum otherwise they would not put thier reputation on the line for thier flag ship car audio amplifier. If not, there would be a classaction lawsuit against them.
