Rockford Fosgate's stuff is generally pretty good. Their lower end products (sold in Best Buy) are kind of garbage in comparison to their mid and upper end stuff. I actually had a buddy that had the FNQ's for a little while and they sounded pretty good.
I have an Alpine 4-channel running my Infinitys in my car. I really like it. It replaced my older Pheonix Gold. I miss my Xtant though. Couldnt ever get the correct part from them. THAT was a great sounding amp.

What would you guys say for a decent 4 channel amp. Rockford, MB Quart or Alpine?
I'm currently running an Alpine/Polk setup in my E39. I've had an Alpine MRP-F600 in my car for about a year and it's been rock solid. Mids and highs sound amazing and I've never had it overheat even when pushed to the limits.
If money wasn't an issue I would look at JL Audio's Slash Series but I really like their stuff alot so I'm kind of biased.
Alpine are quite nice for a discount brand. Big fan of infinity and boston acoustics for slightly higher/mid range $ stuff. Rockford stuff hits pretty hard, never heard that particular model, but I've seen a few RF setups that were decent for the price. Though I must say they do hit hard, but sound muddy. Thats my only negative to say about them.
