BTW way, the pdx-4 is not a marine amp and if used in the saltwaterenviroment , it will not last.

The Alpine digital thing is just marketing b.s. All the signals that come out of an alpine or any "mobile" stereo are analog. If it was digital you would either use a fiber optic cable "toslink" or a single digital 75 ohm "rca" cable.

The Alpine amps are class D analog, put a digital signal to a speaker and you'll get no output. It must be analog. There are some digtial paths in some of this equipment most likely only in the head unit but any CD player is going to have a digital signal path until it goes to the D/A converter. Other than that its a waste, to convert from analog to digital and then back to analog. The more converting the lower quality the sound will be.

just get a good 6 channel amp with a 2 channel low crossover and be done with, run anything you want.

well i have been thinkin about it and im gonna scrap the bose idea. What im thinkin about is buying 4 alpine 7" speakers to hook up to the amp and that will be my system. Was lookin at the JL speakers but man they are double the cost of the alpines

I did the 7" alpines. bought them from sonix electronics. great prices and fast shipping.

How many speakers are you going to run off the pdx amp??? You could run 4 of speakers off of 2 channels on the amp and then run the woofers off of the other 2 channels.

The amp is fine at 2 ohms and it will be fine for marine use.

Do as Griff said and then get a pair of Boston Acoustic G3 10" subs, you can run these in either 2 ohm stereo or 4 ohm mono.... I promise you there better than Alpine subs and equal to JL Audio. IMO Alpine makes great head units, pretty good amps, but there speakers are just OK when compared to other high end stuff. If they sound good to you thats all that matters but I really think you would like the Boston Acoustic stuff better.

As long as you don't get the Boston Acoustic G3 10" subs wet. They are not marine speakers. I put non-marine woofers in a boat a long time ago. They did not last. The humidity killed them in 3 years.

I would just run them off the amp that you have then.
If you want to add subs later, then get a PDX sub amp.

I have 2 Alpine 10" Marine subs and they sound just as good as the JL marine subs for less than half the cost. I also run 8 DC Gold speakers off of a PDX 4.150.
