If you have a decent interior volume you can attain some surprisingly good sound in a vehicle, but we are talking large sedan or minivan size to do that. You just can't get really high quality sound in a small space, especially pne with an open top or soft top.

Original stock speakers in auto sound systems are generally very cheap - you are lucky to see a driver that costs as much as your weekly coffee budget, so upgrading the speakers is the biggest step up.

Mike is quite right about the challenging environment a car presents and I have limited myself to speaker upgrades for that reason, unless the electronics happen to be egregiously bad in a particular car.

There is at least one car I can think of with that situation...

I absolutely agree that a vehicle with a voluminous closed interior has an advantage over our tiny space. However, being able to turn up the volume can overcome the wind noise. I don't know who on our forum has a motorcycle, but I do. The 4 6.5" Polk audios that I have on my bike pointing directly at my face are loud and clear at over 100 mph. My Sky setup now has speakers on the A-pillar that cannot be muffled by wind noise. I added an extra 6.5" in the door for even more high and midrange db. The subs that are 4" away from your back are omnipresent. So, top down=no problem. Picture turning up your headphones to drown out noisy people.

What kind of amp setup do you have? Did you have to make any adjustments under the hood to compensate for any additional current drain, or is the alternator and battery able to keep up?

See post 246-forward for setup. All stock on alt/batt. Bass is turned way down. But when thumping hard, system will dim lights For now, at the levels I play it, it is fine. A capacitor would help it though.

See post 246 and forward for setup. Stock Alt/batt. System will dim lights when thumping hard. At the normal level I play it at, all is fine. A capacitor would help for those 'special' songs.

At the levels I use, all is fine. However, The bass is turned WAy down. A capacitor would help as on those 'special songs, it will dim the lights. I have a cap that is on the do list.

Setup starts at post #246 . Alt/batt is stock. At the levels I play, all is fine. However, on those 'special' tracks, the bass will dim the lights. A capacitor would help for that. I have one waiting to go in.

At the levels I'm using, all is well. However, the bass is able to dim the lights on those special tracks. A capacitor would help with that. I have one waiting to be installed.

You know? You should buy a capacitor! That might help.


Actually, all seriousness aside, would a capacitor really help? I can't see how it's charge would not stay level with the battery voltage. Unless the battery to capacitor circuit has appreciable resistance, or you have a diode between them. Please report back when you install, and tell it if really does help.

Cool. I couldn't tell when looking at the spec sheet for the sub, but are those single or dual vc? I'm guessing single, hooked up in parallel?

You'll note in amp specs that they're rated for 12v and 14.4v, with the lower rated power at 12v. This is because the input voltage is stepped up a fixed amount internally and 12v is a lower starting point. Your alternator is keeping you at 14.4v and it's slow to react to voltage drops. So, it comes down to the battery to keep you above 12v on heavy bass notes. Batteries are pretty fast but nothing like a capacitor.

During heavy bass notes you will drop below 12v until the battery reacts. This reduces amp output just when you need it most. Putting a capacitor as close to the amp as possible helps keep the voltage up until the battery can react.

The goal isn't to keep the lights from blinking, but to keep the amp's input voltage as near optimum as possible. In fact, to hell with the lights, you want the cap's power going to the amp, but that requires a high current diode and we're getting into industrial hardware there. So, the convention is to put the cap on the amp with just a few inches of heavy cable and just lose some power to the car itself.

Shot of it is, a cap will help the blinking lights some but the real benefits is stronger bass performance. I've installed lots of caps in the past but have never felt the need to use one in any of my personal vehicles. I've done A/B comparisons with factory vans and it makes a difference, but I never run that many bass amps at once and prefer the simplicity of a heavy power cable run directly to the battery instead (and accept any minor power reductions I incur).

If you're talking about the stock sub setup in the sky, it's dual voice coil at the speaker end. However, I've never been able to locate a schematic of the Monsoon amp so I can't say how the voice coils are wired. From the amp chips the Monsoon amp uses I'm almost certain they are tun in parallel with 50w RMS to each coil. The parts spec out that way, and, this ties in with the factory claimed amp power output. Otherwise, it'd be 50w short of what's claimed.

Typically, amps are rated at 12v an at 14.4v, with the lower output being at 12v. During heavy bass notes system voltage will drop below 12v since a car battery is slow to react, reducing power output just when you need it. A "bracing" capacitor in close wiring proximity will hold voltage above 12v until the battery reacts. This is their real function. Helping prevent car lights from dimming is a matter of the cap holding system voltage up in general, unless you have a high current diode in place to prevent it. In reality, you want all the power going to the amp and not caring about the lights.
