If I am going to be running an external amp does it matter if I get the higher powered 9833? The 9833 is only $50 more than the 9831. Should the 9827 even be considered?
not only the sound features are better check out the display & you know
btw the sound tweaking is so complex that it's impossible to tune it by ear even if you're used to adjust regular EQ's, you must have it adjusted by a professional dealer. so consider that extra cost. you can of course have good sound without that, but to get what you paid for it's a must.
if you're willing to spend that much for a HU don't consider 2nd or 3rd place for just 50$ difference. you will feel sorry afterwards I garuantee. It's one beautiful HU for sure....
