You cannot effectively drive 1000w (RMS) amps using standard 12V battery supply. I have tried every trick in the book and you cannot maintain 14V for more than 10 minutes with the volume cranked up. I have now added a second high output alternator hooked up to a small battery in the back and two 2 farad caps. This goes straight to my Alpine MRD100 mono block amp, what a sound, sets off car and shop alarms continualsy!!! -------------------- |

Thanks for the comps guys, we over here will normally take out the AC unit and replace it with a 2nd Alt. However as you can see by the pics all stock parts are still in. I had to move the fuse holder to make room. The difference between 14.4V and 12V on my Alpine MRD 1000 is 500W to 350W @ 4 ohms. This is more pronounced at 2 ohm loads. So 2.4 volts makes a big difference to my bass and when you chuck in the AV and under car lighting set up 7 tubes (exterior) and five tubes (interior) you quickly run out of volts. I also use a auto blow electronic fuse in the engine bay and another in the boot just in case The line is severed in a crash as I do not want to fry with the caps pushing all that power (3 Farads). I am now looking for Solo Baraic (square Sub 15) and a beefy mono block to claim top spot in the Bass stakes. Any ideas on this setup guys???
