Wiring question
I intend to put a pair of Infinity Perfect 6.1s and a pair of Kicker
SSMB8 8" Midbass in the front doors of my vehicle. I currently own 3 amps. One 4x50 Crunch amp, one 2x100 Crunch amp, and one Orion XTR800. Obviously I'm going to use the Orion amp to power my subs so we will take that one out of the equation. I'm assuming that the 4x50 Crunch amp will be too little power for this setup so I've already decided to sell it. My question is, is there a way to use a 2 channel amp to power this setup and still make it sound good or should I purchase another 100(+) watt amp and use the Crunch 2x100 on the Infinitys and the new amp on the Kickers? Also, if I purchase another amp, is there a way to lower the ohm load that an amp sees if you only have one pair of single voice-coil speakers attached to it? I only ask this because I may find that I need more than 100 watts for the Infinitys and I'd really like to be able to use the amp that I currently have. Any help you can give would be greatly appreciated. |

Thanks for the advice. Hopefully that will be enough power. 125 watts for midbass and 100 watts for midrange/treble...I should hope it will be enough! I mean, think about a home system (watts are watts, you know), would 225 watts per channel for the fronts be considered enough (and that assumes an outboard sub!!)? With the advent of class D and other technologies in the last 10 years, I've seen power specs balloon in automotive amplifiers (ten years ago, a true 1000 watt amp was rare) and we have all become a little watts crazy, mainly because when it comes to bass, there's no such thing as enough power (and that certainly goes for me!). But here's the dirty little secret that most amp manufacturers don't want you to know (I worked for Phoenix Gold in Portland, OR): if you're pushing much more than 500 watts, your stock electrical system probably can't keep up. In other words, if you go and buy that 1500 watts class D behemouth (or fill your car with 200+ watts amps) without buying a new alternator (caps help, but can't prduce power from thin air), you are basically wasting your money.

The only reason I'm concerned about it not being enough power is I want
to be able to play my music loud and still have it be clear. A little wattage headroom can't hurt, right? Also, I drive a ZX2 so it tends to let in a lot of road noise. Sound dampening materials help somewhat but they can only do so much to compensate for cheap auto engineering. I certainly agree that I will have to upgrade the alternator. Currently I'm running front and rear speakers off of my Alpine HU and I have the 2x100 Crunch amp bridged to my subs and certain music already causes my lights to dim a little. How sad is that? |

Remember as well that simple wattage cannot give you loudness, one needs cone area to use that wattage wisely. -- Cyrus *coughcasaucedoprodigynetcough* |

The only reason I'm concerned about it not being enough power is I want
to be able to play my music loud and still have it be clear. A little wattage headroom can't hurt, right? Absolutely. In fact, after I wrote my last message it occured to me in the home audio world audiophiles go out and buy 400 watt Mark Levinson monsters just so they have the headroom. The point I was trying to make in my last post (but it didn't come out very clear), is that 225 watts per channel playing 80 Hz on up (with adequate speakers, of course) should be able to make most human's ears bleed. If it does not seem clear enough or loud enough to you, chances are it is because your electrical system can't keep up with the demands of your amps. Maybe this does not apply to you (perhaps you have a large aftermarket alternator in your car), but I thought I would throw it out as I see this problem all the time. Upgrading your electrical system is expensive and certainly not as fun and sexy as that big, shiny new class D amp, but if you want big, CLEAR sound, it's just as necessary. MOSFET |
