Amp upgrade advice.

[2012ScionTC 10+ year member]

On a budget but looking to upgrade my Rockford Punch P400-4.

Currently looking at local used amps and found two I am interested in @ $300.00, looking at amps that produce 100 x 4 @ 4 ohms.

Which one of these choices, Alpine PDX4 or Rockford T600.4

Classified amplifier on this site Skar Audio 85.4? for $225?

Thanks

The Autotek looks interesting, probably nice but old school means probably a pretty old amp.

Fujitsu looks like might be more power than what I need.

BK520.4 PRECISION POWER 4-CH PPI AMP 1040W MAX SUB SUBWOOFERS SPEAKERS AMPLIFIER now that looks like it would fit the bill and great price, I'm not familiar with the brand though, how are they compared to the Alpine or the Rockford Fosgate? Woofersetc and $199.00!

I'm tempted to click this one! Thoughts? One other thing, I currently am running a Rockford P400-4 and JL 500/1 and have done the big 3 upgrade with 0 gauge from knukoncepts. No headlight dimming at all. Think I will be okay/safe with the amps I'm looking at to upgrade my 4 channel with my current electrical system (100 amp alternator).

Thanks!

I agree on the zapco just want to be sure I am in the 100 watts @ 4 ohm range.

Never means a more powerful amp is bad that is why there is a gain. Hence the recommendation of the xa4000, full range class d amp which makes it quite the efficient 4 channel.

The eclipse over all listed so far. But if you wanna keep under $200 then the PPI fits.. Not as good as the ole PPI but good enough. Check classy for $200 bucks you should be able to find a solid 4 channel.

Okay so of the Alpine PDX 4, Rockford T600.4, Percision Power Bk520.4 and the Diamond D600.4

Would the Diamond D600.4 be the best choice?

Tough decision here. I like the looks of the diamond though and I'm sure the wife won't mind me spending the money on a Diamond... right...
