Yes, The RE8 has an un-believable amount of excursion just like the W7 //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

No.

If you do move up to a w7, dont put a profile amp on it. Profile amps are good budget power, but if you run a w7, chances are you will be able to afford a better amp.

According to that, your box is only .77 cubic feet. The recommended sealed box size for an RE8 is .22ft^3 - .40ft.^3, so yeah, go a little smaller.

Perfect //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif, I'll just use my box my optimus pro series is in. Its only 0.598cu.ft. but its a bandpass enclosure

Whoa, I think its going to vibe! //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif

I dont think you need a new amp. If its rated at 300 watts max its probably putting out about 150 watts rms into 2ohms (assuming your running dual 4ohm voice coils paralleled) which is enough for an RE8. Besides you dont need anybody to tell you if the amp is sufficiently pushing your sub without excessive distortion, you have ears. On the video it obviously being pushed past musical (if you can say that about what you were playing). its obviously clipping as well, you can clearly see the excursion is not linear in the video. If the amp is pushing the sub sufficiently under "normal" operating conditions (when the music still sounds like its suppose to. think how it sounds at low volume only louder with no additional audible distortion) it probably poweful enough. you just need to turn it and/or the bass down to normal levels or get a bigger sub/amp package if thats not enough.

and of course the speaker sounds louder the louder you push up the crossover frequencies, the higher you push the x-over the higher frequencies the sub is playing. its not playing louder its just playing more frequecies than when you have it set at say 70hz. Your other speakers should probably be playing anything about about 100hz.

oh I see.. Well im not wiring it parallel, Im wiring the sub is series because the amp is not 2ohm stable, gotta be at 8 ohms because if I leave it at 2ohms, I will fry the amp. Id love to hear the sub wired parallel but I just can't

 

[klassic 10+ year member]

well in that case you probably do need a bigger amp. it probably is only putting out 50-75 watts rms. still a fun video to watch as far as car audio goes. I think I'm gonna go out and make me a video of my diamond M6 just because I've never even bothered to watch its excursion although car audio **** usually doesn't excite me too much.

But hey klassic.. Its still pretty loud though. I can hear the sub all over the house when I play it in the drive way.. Rattled my bathroom door knob and windows lol. but the main point is that the sub sounds great in the car which all that matters //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Here is the box im putting it in.. .5cu.ft. bandpass ported

Here's the RE8 aside to the Optimus Pro Series 8. OMG The Optimus sub looks so fake! //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif

Pictures sponsered by Logitech nah j/k. Pictures was from my webcam.. Not bad quality.. pretty decent anyways, Im gonna put the sub in the box right now.. catch you guys laters! //content.invisioncic.com/y282845/emoticons/up2something.gif.dd110ecf3ae4b76050d87598f2f8de7c.gif//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

Okay.. I really don't like how the sub sounds running through the bandpass because it makes too much "Whooossssssh" sounds so what I did is that I stook one of my old stockings in the hole so it has a seal, Then I put electrical tape over the bandpass hole so it blends in with the box. And I had to leave a tweeter in the left side of the box because if I take it out, theres going to be a big hole so I needed to leave it in there to seal the box airtight. The tweeter is not hooked up by the way. And I like how it sounds better sealed. Louder than through that bandpass hole and the smaller box is LOUDER than the bigger box I had it in.. Id say 6db more because it was a real difference.

I was playing the song "Hate it or Love it" and the drum beat has a little punch you in the chest feel... By the way my system setting is = Freq at 100hz, Gains at 3/4 volume, Bass boost=on(Adds +6DB).. HU eq= Bass= 0, Trebble=+6, Balance=0, Fader=0,Magna Bass=Off.

So I usually listen to my stereo at volume 22/33. And if I don't want the door speakers that loud I turn the volume down to 16/33 and put the Magna Bass=On so that the bass still thumps.

So yeah so far so good. With this settings I decide to see the sub excursion so I open the trunk door and the sub doesn't look like its stressing or clipping. I should make another video of the sub to see if the gains is alright or I can turn it up a little louder. Well, lets see.. What test tone is great to set gains with, Because its hard to tell if the sub is distorting.. It has so great quality!//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

What's the mounting depth on that thing?

 

[kuijo 10+ year member]

Put it in the box you like and then i've heard people throwing peices of wood/mdf in the box to take up airspace inside the box. to lower the cf.

 

[Basshead808 10+ year member]

Well, My mom says its louder in the smaller box and I think it is because my rear view mirror shakes alot more... I love car audio //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
