It's been quite a while since I bought an amp. The industry has really changed, and for the good. More features/perfornace for less cost. I've mostly owned Alpine and Precision Power amps, and I tried to buy another PPI, but they were out of stock, and I took a look at Rockford. The prices were pretty good at this time so I took a chance.
The P400x4 is compact and heavy. I was surprised at the quality of construction, really nicely done. Things like that can tell you a lot about a company. Anyway, the feature set is also quite good, and being able to double the wattage from 4 to 2 ohms is seriously impressive. And the bottom line of course is the sound. This amp is really nice sounding. I'm running a set of Pioneer components, and the amp drives them effortlessly. They don't have much low bass, so I won't comment on that, but the balance and quality of vocals, instruments and highs is really good for the money. Imaging and soundstage, it's all there. I'll be buying another amp next year for the subs, and it'll be a Rockford Fosgate.

I changed up my system as I upgraded the wimpy stock 6x9 speakers on the back deck of my Altima with Pioneer TS-D6902R. I'm now running 2 channels of the amp to the rear speakers, and the front comps get the other 2 channels. Wow. This amp is making my jaw drop running all speakers full range. Lots of tight bass from the 6.5 and 6x9's. Clear, clean, effortless and more volume than I can handle. You really can't go wrong with these Punch amps.
