[QUOTE="HardofWhoring, post: 8842577, member: 674149"] You only need 1 preout for each amp. If you are hooking it up to sub amp, then you're good. I would look into what the preout is specifically for though. It most likely is for a sub in that it's an extra channel, and you can adjust some of the parameters before sending out the signal, such as a pass filter or volume boost or drop for that channel. If there is a chance you might want another amp down the road, you could also look for an amp that has it's own preout. They all have signal in, but some have there own signal out (preouts on the amp) so that you are basically daisy chaining the signal. There's several other ways to solve it if you don't, but just a though. As far as 4v, a higher voltage makes for a cleaner signal, but its for subs, so don't worry about it. If .8-.9 cu ft is before the sub volume, is that also going to be interior size? We're getting small, and to the point where you really need to consider (1) 12", and at least do the numbers. Are you trying to go ported or sealed? How did you come up with 300w rms? That's a small powered subwoofer. Are you wanting to feel it hit, or do you want a little bump that will help the sound quality of the music, and you aren't trying to upgrade your alternator or battery? Two 10s on 300w will NOT make your car shake like crazy. Two 10s on twice that and were getting close, but "shake like crazy" is relative. [/QUOTE]
