Decaf

Both are great products. This is the SS section though so thats as far as I'm goingI use just iso alcohol or windex to clean... something that doesnt leave residue that can get rid of dust and any oil/grease. Interiors will sound better, lows improve usually so its a win win

I used about 7sqft of AT per door so that should be enough (saturn) tightening the latch that holds the trunk made a major improvement with my car. it improved the stock weather seal and reduce a ton of vibration. then i filled in with great stuff so no air leaks out of the trunk lid... then 2 layers of 60mil AT deadner

Sound like you have the subwoofer amp rcas connected to front/rear outputs on deck.

Thats fine for this unit but that does not work with all dvd units

"Bypass" is just a $4 bosche relay

your headunit sub level should be at +15 iirc and RCAs do not clip at/near full volume of 35 as your voltage drops you will clip the amp sooner, which is also what is happening. basically you arent even running the amp full power at all, if you were... you would have more issues than "low 13s" (n8 pioneers usually are clean full voltage at sub level 0 to +2)

si, weather stripping and rope caulk will only work if the sub is taken out

pretty much spot on. google should help, youtube should help... or the search feature on this website.

weather stripping at lowes/home depot/menards is the same thing and cheaper

Your assumption is correct in that it would be the same as saying you set sub amp with 0dB that 0dB songs would "play the best" There's no specific "method" that works because every song is different and recorded at different levels. Learn what distortion sounds like, learn what clipped kick drums sound like, and finally learn how clipping bass changes the mids/highs so you can pick out the unwanted sounds. Using WMP Oscope helps visual clipping while your ears listen to it, its a good training tool. I suggest to purposely clip tracks using the WMP graphic equalizer...boost 31/62hz +6 to +12dB so you can hear what happens when songs are clipped badly. I've stated all effects I use in the "teach me about audacity" thread in this section. Bigpimpn/Autruche(?) added in info in addition to what I posted. Alright cool I'll deff check out that thread and so I've been playin around with wmp for a little bit here I'm using the scope and got the equalizer open should i be setting every frequency to my desired db e.g -6db? No. Im suggesting to ruin the song while its playing to see what it looks like so you do not "edit" songs that are terrible candidates to start. You cannot get all of your songs to be at -6dB, not possible. When setting gains you use a tone that is the average of the music you play. Plenty of times songs straight from a CD will be louder than -6dB resulting in a bit of clipping, which every single one of us does everyday. Even if you set gains with 0dB you can still play a terribly clipped song and the amp will produce the amplified clipped signal. 0dB is the safest setting but you compromise the loudness because very few songs are at 0dB all the time. Most songs are between -10dB and -5dB. ahh gotcha ok last question lol I see in the equalizer when you adjust one frequency it automatically moved the ones next to it is it supposed to be like that? and also so if I have a song that has clipping in it is there a way to "un-clip" the lower frequencies my subs would play in wmp? there are three options on the far left under turn on/turn off. pic the top option so you can individually move each. no, you cannot remove clipping, you can lower the amplitude but it will be the same waveform.

Rope caulk is cheap and wont show. What sub?

clean signal is a clean signal regardless what the deck needs to get there. good info orion by the logic above alpines are the best units because you turn them to +15 and pioneers are the worst because they get full voltage with a lower sub level, duh... it does not work like that at all.

I responded to this yesterday but I couldn't find the thread and thought it was deleted...hmmm Its usually just mids/highs. Here's a recent song I've done vs a sine wave. From first glance the song looks worse because you can see some red lines Now after zooming in you can see that I was able to make a SEVERELY clipped sine wave and simply lowered it below 0dB so it wouldn't clip/turn red to prove a point. The show clipping/find clipping feature will only indicate if ANY frequency has passed 0dB. It will not indicate horrendously flat bass lines that will keep the sub at peak voltage and reduce cooling abilities. That one red line is less than a ten thousandth of a second, even though it reaches 0dB for a split second it will never cause the damage the sine wave below will. This is why the object of messing with music should not be to eliminate all the red, nor should you be HPF'n/LPF'n the track the get rid of red... that is absolutely the wrong thing to do. You are missing a huge aspect of the song that dictates how it will perform on your stereo if you never zoom in. The waveform of the bass line is key. First watch the song through windows media player oscope, then if its clean enough send it to audacity or whatever your favorite program is. Then zoom in and examine what the song looks like. Most rock, dubstep, rap , heavy metal, RnB all straight from the cd will reach 0dB and turn red in audacity, you have to figure out how far past 0dB it is, and if it cause damaging clipping that is audible and detrimental. Also, remember that no speaker is getting the full bandwidth of the song... so while a recording may be at 0dB here and there, the signal is separated to each speaker via crossovers which reduces the power and signal. For example, lets say 0 is silence and 30 is the loudest. A song could have 25 units of bass, 3units of mids and 1 unit of treble. Collectively they add up to 29 and in a few spots the song turned audacity red. But once you separate the bass and send it to the sub amp its only seeing 25units, not 29... make sense?

thisi can't imagine the flux is the same either

dont mess up the series/parallel wiring like you did with the AQs....

positive on master is positive for speakers positive on slave is negative for speakers connect master negative to slave negative to complete the strapping

Correct, if you play loud rap setting gain with -15dB tone will cause clipping. Using the -15dB tone will have the gain in the closest position to max gain compared to using -5/-10 which are safer and closer to the loudness of the rap music being played

this is the difference0dB for headunit/least distortion -5dB for amp gains/sq setting << what i use -10dB for amp gain/compromise << what most use -15dB for amp gain/spl setting << too quiet for rap music max would be volume 34 in this case "-15 too quiet for rap music"? i find a break in your logic here. tuning with -15dB (track 7) at the head unit and using a dd1, would mean that your turning your amp up higher before getting distortion, so obviously when you play a regular cd it will be louder than if it was tuned with -5 (track 3) or -10 (track 5). what would be too quiet would be tuning with track 3. that is unless your going strictly for quality but i like my shit pounding loud. You never use -15dB for the headunit, you always use 0dB to get the cleanest highest voltage possible. Rap music bass is louder than -15dB, thus anything louder than the tone used to set the dd-1 on sub amp will push the amp into clipping. Most rap music is between -5dB and -10dB, so using -15dB means most of the time you are +5dB into clipping. There is no break in logic besides yours.

what about the amps LowPassFilter, whats it at? what about the headunits LowPassFilter, whats it at?

well you have an extra .8cuft when entering the correct bracing (measure and find exact volume) which should be enough to account for the extra port wall since you use 2... i'm just suggesting even loading instead of port on one side. this is sub up port back

Its not about Port Area/Cubic foot... its about volume displacement/power/desired f3 Vd=xmax*sd... so the more the subs move the more port you need. Sd should be used when comparing woofer size setups, not area of a circle The more power you apply the more notes the sub will be closer to xmax thus needing a bigger port. This is also why on low power you can get away with smaller ports. So long as volume/tuning remain the same a smaller port will have a lower f3(becuase the smaller port is able to maintain backpressure/cone control) compared to a larger port. A larger port will have more of a peak in response

I've built and designed tons of boxes using joex's baffle style with NO issues. Build it correct and that does not matter at all. If baffles are coming apart its from panel flex or not enough glue/clamping force when glue set. I'm using the same box I built in 2007 and its just as strong as the day it was built.
