Should you use speaker wire for power wire? Speaker wire and power wire are the same thing as long as it's the same size/brand.
Can you still have distortion when using a LPF? Yes
Can you send a clipped signal to a subwoofer? Yes.
What is a clipped signal? Dirty power
Should you play a song farrrrrrrr below tuning? No, because it can bottom out the subwoofer.
Do voltage & amps matter when powering an amp? yes
Can an average human determine 1% distortion? Very doubtful.
Can you under-power a subwoofer even if "Scoped" or using DD-1? Yes, because some amps won't magically make up for the wattage just because you tuned it correctly.
Are kicker amps the only amps that do rated power? Hell no lol.
Do ohms matter when connecting subwoofers? yes
I answered what I could.
Hey man, thanks even for the ones you did answer.
yes power and ground sizes matter. would you rather have your house on fire (like a 3000rms amp) and have the firemen use a hose the width of a garden hose (8 gauge), or have them use a fireman standard hose (0 gauge).
speaker wire as power wire? no. power wire as speaker wire? yes.
the gain knob is used to match the voltage coming from the headunit preouts. higher gain doesn't mean more output. it just means you'll reach the amps max potential output sooner on the turn of the volume knob.
distortion when using LPF? i dont see why that would matter. all the lpf does is cut out frequencies higher than where the knob is set to.
no, about the headunit distorting and tuning amp gain.
clipped signal to a sub? you bet your fucking ass its possible. and it happens every single day to thousands of systems.
find wiki article on what a clipped sine wave is. maybe this can help. http://www.azimadli....heirspectra.htm
playing songs below tuning? is your cousin really that retarded dude? why would that be a good idea 99% of the time?
yes subwoofers can unload in a box. its almost always when you're playing below tuning. and yes they can unload in sealed boxes too.
voltage and amps. if you dont have enough of either, you can blow your amp and/or damage other equipment. thats why people buy $500 alts and $500 to thousands worth of batteries.
1% distortion? on mids and highs maybe. on subs, fuck no.
acoustics? yeah. why do you think those extreme vehicles fuck up the whole interior and make those funky shapes and curves? to get as much pressure in one point as possible, aka where the mic is.
yes you can underpower a woofer when scoped. unless you're running like a 1000w amp to a 600w sub, then you're likely underpowering it. box rise is a bitch.
ported = vented = "port holed" wherever the hell that came from.
an amp is basically a giant DC to AC converter, using the signal generated via the headunit that is transmitted to the amp via the rca cables.
lots of amps do rated. not even gonna get into that. but some companies lie about power ratings, like power acoustik, kole, boss, etc.
ohms matter in a way that, if they're too low, you'll blow your amp. and if they're too high, your subs will barely get any power.
wire size does increase efficiency. less resistance in bigger wire than tiny wire, allows more current to flow through. i refer back to my fireman analogy
12v has MUCH more current than 120v. notice on 120/240 universal products, the 240v rating has a lower (about half) amperage rating than the 120v one.
haha wow, totally answered more than I thought any, one person would answer on here (I believe all of them) Thanks ALOT.

So today i was in a little debate with my cousin on car audio since I recently put a system in my car, so I wanted some of your guys' knowledge, preferably well known, respected, people that have experience. I told my cousin that I'd ask some knowledgeable people so here it is. Anyways, does power/ground wire size matter? and why? Should you use speaker wire for power wire? What is the purpose of the gain on an amp? Can you still have distortion when using a LPF? Can you properly tune an amp without knowing where your head-unit distorts? Can you send a clipped signal to a subwoofer? What is a clipped signal? Should you play a song farrrrrrrr below tuning? Can a subwoofer unload in a ported box? Do voltage & amps matter when powering an amp? Can an average human determine 1% distortion? Do acoustics come into play when talking about loudness of a setup? Can you under-power a subwoofer even if "Scoped" or using DD-1? Is ported different than vented & port-holed? Does an amp turn DC current into AC current? Are kicker amps the only amps that do rated power? Do ohms matter when connecting subwoofers? Does wire size increase efficiency? Why don't washer/dryers/dishwashers/microwaves use massive wire if they have 120v & not just 12v?
If you guys can answer as many questions as possible I would GREATLY APPRECIATE IT.
It's super late so I can't remember everything that came up but that's a pretty damn big list.
-Thanks

When you use the lpf @ 80hz on a song in audacity, is that what the same signal that your sub amp sees?
-
Hey so will we ever be able to post our slowed & boosted music on here ever again? jw cause I've done a lot of songs lately & wanted to share them with people.
-
ok so many questions .. how does it sound ? and i was looking at the stage 4 head unit is it worth getting ?
Not unless you're looking to compete in SQ or brag to your friends. Other than that there's really no reason to buy a head unit for a grand. Does look like a fucking awesome HU though.
& OP, that car is sweet. Awesome craftsmanship.

I would use Virtual DJ to chop n screw & Audacity to bass boost & EQ
-
Regulate I think is right around there 52,53 some'n like that. Pretty much any old-school hip hop is in the 50's (Hertz Wise).
-
Its only worth about 300 on the street.
I usually buy them for 100-125
Damn! You should give me your hookup. lol

Wouldn't moving up or down on an EQ be the same thing? Say if you have bass,mid,treble & the bass is too overpowering so you turn it down, wouldn't that be the same as keeping the bass the same & turning the mid & treble up. As long as you have a clean signal it shouldn't matter. Correct me if I'm wrong, I'm not a Musical Engineering expert so I could be wrong.
no, if you turn up something past flat you are increasing the signal and risking clipping and distortion. and more bands aren't always better. i have a 28 band e.q. and it seems like i am always tweaking something. but i always cut, never boost.
Yea, but it should all be good as long as you aren't causing distortion.

Look at the comments, everybody says it must be the SMD forum.

I lol'd @ your "Where?" in the text.
& if RE can make a wall for 6 8's in one of these you should easily be able to make a nice ported with 2 dc 8's or something.

300 posts. A request in the 18+ request thread. And ultimately Nate's decision on if he thinks you're mature enough to enter lol. And whenever he decides to update it.... Which could take months lol.
ok. yea, I "signed up" I guess with the I am over 18 thing so I guess now I wait lol.
-
I was just wondering if anybody knew how long you'd have to wait to be able to "enter the +18 zone"?
-
I'm using Rockford Fosgate 14g Speaker Wire w/ a kill switch & everything works fine, takes a while for the amp to turn on after I flip the switch though.
& I've done what C. Director said to do a few time when I used wal mart 18g
-
Maybe they have the gains down so people dont blow shit up.
I think that's what the best buy here does cause I swear everytime I go in the Kenwood head unit sw level is +15 & bass boost on level 2 (Max) so when you even everything out it's pretty quiet even when using their largest kicker amp which iirc is 1000w. They've just gotta be safe.
-
This is my first feedback thread so here it goes.
Bought a Cache CBR Bass Restorer off of him, he packaged the box very well & snug, shipped extremely fast (less than a week), came with all original parts & even left some funny motivational words on the flaps of the box. Definitely buy from him again & suggest him to anybody that wants to buy something from him.

lmao shes almost as bad and as ugly as kreyshawn
Nah, I'd still put it in Kreayshawns butt.
-
I've wondered the same thing cause some people with huge systems say they don't need epicenters to play country & spanish loud but I'm only running probably 400-450w rms on 1 12" so after forever of contemplating it, i bought a cache bass restorer (same concept as an epicenter) off of here & hopefully this weekend I'll figure out if i need to save up for a bigger amp or not (hopefully not though.
-
youtube was being weird for me so I wasn't able to watch your video (try posting the actual video on her instead of a link) but I listened to the song and it's vocals are wayyyyy too quiet & sound little weird but the bass isn't clipped to hell or anything so that's good.
-
Only issue is one crossover is missing the cover. That's probably like 100$ right there lol
haha at least.
So how did you manage to get those for free?
-
Damn!!

Please answer these questions!!!

Hopefully all of these answers will be enough for my cousin to never bring up car audio again but we'll see. I tried not to make it obvious whose questions were whos, but you guys are too smart & know when teh newbz are present. lol
