[Learned I was spoiled by SMD last night.]

Show him this build.

Eventhough it's a build from belgium, it's on here so..

[Broken ZCON...]

What is the size of the box and what is it tuned to?

What amp are you exactly using?

[Noob question...]

are you going to connect 1 sa 15 to that amp? If so ill wish you a lot of good luck, especially since you need help with wiring and want to power a woofer with double the power.

[Would you brace this sub box?]

Add some bracing at the 40 inch long panel, 40 inches is quite a lot.

[How much power do I need?]

Easy thumb of rule is.

Take the wattage of all the amps and divide by 12, that get's you the amperage you need.

example: 2400w divided by 12 equals 200A. So you need a 200amp alternator and a g31 battery extra per 1000-1200 watts. So 2 big batts.

That's if you want a good electrical. A little less should work if you don't play music for longer periods or not at full power.

[RUSTY you got some guys talking sh1t about ur amps!]

Thats what ive been trying to say damn it lol

But your name isn't rusty...

[This is not a versus thread.]

Any suggestions for a 12" sub that handles double bass, just as well as rap? I need sound quality.

Take a pick out of all subs, you don't seem to be looking for sound quality, you just want something that doesn't sound like shit.

Alpine type R would be a great allround subwoofer.

[Peaky box?]

He has a PSI recone... on a sonic sound lab.

Lower port area and tuned lower should help with the lack of lows at high volume.

A new bigger box is needed i assume with the PSI recone.

Inverting the sub won't really help, but try and see for yourself.

Team bassick, you can't play LOUD all the time so he should better fix the box. Because if he says that the box is peaky, then it must be really peaky.

Btw, you won't hear a 2db difference.

Never seen a box act "peaky" at low volumes???????

Only at near or full tilt

was that sarcasm or what?

I said myself that lower port area will help at higher volume, but not as much at low volume.

Yes, higher volume can make it sound less peaky.( most of the time it sounds lower with more power.)

EDIT: Nevermind, Team bassick , i can't seem to express myself correctly.

[Enough for 4k+?]

If you want to go cheap , keep the amp and don't upgrade to 4k.

Simple as that.

Get a alt at mechman, atleast 250 amps.

4000watts divided by 13volts= 307 amps, that's only if your amp was 100% efficient which it isn't. It's about 70%(although 60% would be more realistic.)

so 307w times 1.30(=130percent) equals 399 amps to only power your amp.( to be honest in real life it will be about 200-250 amps)

Your car also needs electrical so add about 50 amps to it, even more with AC on .

That already 250-300 amps of current draw on the car electrics and sub amp. I assume you have a amp for highs too since it would be rediculous to only use 12W from you HU if you have 4kw going to subs.

See why you need at different alternator?

Batts don't make power, they only store the power the alt makes and release it when the amp needs it.

[motorcycle insurance and brand.]

why would i be a squid? If im saying he should start out with a smaller capacity bike?

Excuse me for saying drive, i wasnt very awake and english isnt my native language so i make mistakes from time to time.

[motorcycle insurance and brand.]

if its the first year of your license it will be that high.

Less cc=less insurance, and its safer to start out on.

Youll learn a lot more about cornering, and how you have to handle a motorcycle with a slower bike, because you need the keep the speed more constant to be faster. A normal 250cc should be able to go to 60mph in 7seconds. So its not slow.

A honda/kawasaki/yamaha 500cc would also be a good starter.

Dont start out on supersportbikes like gsxr, yamaha r, cbrs.

Most of the people who want to start out riding those only want to go fast instead of actually drive a motorcycle.

[deleted.]

I wouldn't use 2 18's or 4 12's in a CRX, use 2 12's, that should give you the best results.

[Where to have RE Audio XXX 15" Rebuilt?]

I would use a FI recone, just like forum asshole and bron of bass said.

Psi has been known to sometimes use low quality materials.

[SMD DD-1 compared to JBL GTO EZ-501 Amp (internal gain setting technology)]

That amp looks very nice.

It has been a long time since end caps were used and i sometimes miss them.

I think it's a nice feature JBL has put into their amps, but like you said they should better say to turn your deck up to a few notches below max volume.

[Ring terminal difference?]

You will not see a performance difference. Just pick the ones you want.

[Is there anyway to increase MPG?]

• Lower your car - better aerodynamics won't help in the city.
  
• Keep you car washed/waxed/clayed - once again, aerodynamics CERTAINLY doesn't help at all. Not even 0.1MPG
  
• Clean air filter That works
  
• Clean injectors Only works if they are dirty.
  
• Clean spark plugs Barely helps, only if they are over the limit
  
• A chip would help - but get a better one like superchips or upsolute or something. Cheap chips just dump a ton of extra fuel into the engine making it run rich. THIS IS THE BEST OPTION
  
• If you have a manual car, shift lower, but not so low as to bog down the engine
  
• Go to http://pure-gas.org/ and find an ethanol free gas station. Ethanol has lower btu/gallon then straight gasoline, so without it - your engine uses less gas to accomplish the same thing
  
• Tire pressure - low rolling resistance tires would help too This helps quite a bit.
  
• Lower final drive
  
• Lower stall torque converter (if automatic)
  
• Drive smooth, look far ahead. If traffic slows down ahead of you, just let off the gas and coast. Don't 'hurry up and stop' Most important thing to do.
  

Look at the red parts.

Like dkahns said,the dimpling will help but it's just not easy to do. And noone does it.

[Better SQ amp: MB Quart or Soundstream]

JBL amps sounds pretty good too for a reasonable price.

[Better SQ amp: MB Quart or Soundstream]

If your serious about SQ amps, look at boston acoustics, zed amps, audison, older cadence.

[Best Subs For the lowsss 15" to be exact]

re XXX are one of the best woofers for lows.

[Looking for the best 80mm fans!]

like sheena said, delta fans are high cfm.

But why not choose for a 12cm fan? Like the scythe kaze 3000, its a beast.

[Sausage or Bacon?]

How is sausage even tying bacon, damn sausage lovers...

Bacon.

Offcourse bacon, you know what they say about guys that like sausages...

[Back again with a little more cash]

The AQ220 and Zcon is a good combination.(be sure to set the gains correctly )

But if you go for a 2200W amp, you neeed some electrical upgrades, like a High Output alternator that puts out atleast 200-250amps and a extra battery.

[BASS!]

Too bad it's quite clipped.
