[QUOTE="eharri3, post: 6020608, member: 591579"] If you want louder with the same clarity you should be looking for power and/or stronger subs, not more head unit voltage. All the extra voltage means is you get the exact same clean volume as before but with a different setting on the gain dial. The maximum possible distortion output of your system will not increase, it will simply occur at a point where the amplifier doesn't have to multiply the head unit's signal as many times as it did with the 4 volt head unit. If it wasn't enough for you before, it still won't be now. Despite your statement 'enough background, I've learned my mistake', you evidently haven't. If you had to crank something too much to get enough loudness to make you happy before, you'll still have to do it with your 8 volt head unit. And by the way, 4 volts is pretty darn good, what plenty of people run really good SPL and SQL systems with, and people used to accomplish the same things with half that. Your main benefits will probably be less system noise if you have any now and cooler running amps. The noise reduction will be noticable in mid/high frequencies but you probably won't be able to tell from the subs. That being the case if you just want to do what you want to do because you want to, as someone else said there's Eclipse HUs with 8 volt outputs that are VERY nice. Buy it and chime in again and tell us how much louder and cleaner it makes your subs sound. [/QUOTE]
