    Actually that is not quite true. I suspect you simply mis-spoke.
    7db requires 5 times as much power but is not perceived as twice as loud.
    10db is considered twice as loud.
    10db increase requires 10 times the power.

    I used white/grey stripe for positive and and white/blue stripe for negative.

    Keep in mind, I am using a 2ohm SVC 12. That is using 1 ohm per channel (factory is rated at 1.3 ohm per channel at 55watts). If you use a 4 ohm sub and bridge the stock amp it will be 2 ohm per channel and actually REDUCE the output. Most likely to around 75 watts total output. If you use a 4ohm DVC sub, there is a way, with some screwy wiring, to run the amp bridged and reduce the sub to 2ohm.

    Actually, we kind of are

    See, the vast majority of tracks out there use guitar and bass guitar, and the rest still use the same frequency ranges - whether its classical strings like cellos or modern synthesizer keys...

    Your db/watts bit is just a tad off... I work as a DJ, and have 18" subs that are rated at 1,000 watts, and 126db. Meanwhile, my buddy also has 18" subs, also rated at 1,000 watts but only 104db. All depends on the efficiency of your subs and amps. Every time you double your wattage, you will gain 3db. And as someone said, db is no linear, and that is key to remember. A jet taking off is only 24 db louder than one of my subwoofers...

    Agree 1,000,000.

    I used to be a sound engineer. Owned my own sound production company. FOH, i had 4 pairs of JBL 225's with JBL SRX4719's on the bottom, each dual 18" sub cabinet had a Crown 4000 watt amp on it, so 32k strong bottom end and 8k up top total. Sure miss it, but the wife doesn't!

    also don't forget your subs aren't rated at 126db 1w/1m. Probably more like 100 to 102. 126 is probably topped out at RMS.
