Car stereo guru needed.....

Alpine always seemed to be a good brand to go with. If the specs meet your needs I would go for it. Just to clarify on the amp side of things. I am always thinking of actual output of the amp and not the rated power. For example a 700 watt amp will only really do about 150 watts per channel into an 8 ohm load. So yes for 150 watt speakers I am going with a 700 watt amp but the actual output per channel matches 150 watt rms speakers. This would be the 2 to 4 times amp rating per speaker. Car audio speakers are usually 2 or 4 ohm and not 8 like most pro audio. This way we can add speakers in the chain and not really hurt the amp by not loading it enough. Two 8 ohm speakers in parallel equals 4 ohms on the amp. I understand now why they are recommending the wattage for the amp since actual output is not actually a lot more than the 80 watts the speakers are rated for. Like I said I just convert in my head for actual output most of the time and that's what I was thinking all along.
