alpine pdx series are nice and compact
Stay away from these. JUST got done putting one of these in my car and after running around for two days trying to find the culprit to my high pitched whine it turns out it is the Alpine PDX 4-100 itself and they are known for this issue.

And no...it's EVEN with the car OFF and both my F&R RCA's disconnected! And my powers are seperate from my RCA's and speaker wire. I'm really ticked about it as I like the size and power the amp puts out. But, being I bought it off of fleabay my warranty is void most likely. Can only wonder what it will cost to fix it.

I think he should take a look at the pdx. I have a 4.150 and I don't have any problem with it. I even had a 1.600 and no problem with it.

 
I'm sure most wouldn't consider them SQ amps, but what do you guys think of the V-Power Alpines? I already have a MRP-M500 running a sub. Think I should just get a 4 channel to match?

Here is my thought, theory. Those speakers are 80w rms. Half of that is 40w rms. Add the 40 to the 80 and you get 120w. Get an amp that is 120w...
