I believe an Audiopipe AQX3500 will give me similar performance compared to a similar rated Sundown or Audioque amp. What is different about a Sundown amp compared to something else that does the same power? Power is power. At the end of the day that is why you buy an amplifier. You are paying for customer service that you should never have to use if you take care of your stuff. Besides, just because you don't buy from Sundown doesn't mean you can't get your amp replaced in case something does happen. I had an MB Quart 4125 amp crap on me that I bought from VMinnovations and received a BRAND NEW amp a week later. This is what Sundown nut huggers holler when they get proved wrong. "Oh Sundown has the best customer service ever, if you buy from anyone else you won't get a new amp if your amp is faulty or breaks". I've bought many car audio products on
Ebay and I've always received a brand new item through the company I bought from when something went wrong. Oh and by the way....
I'm completely happy with my one sub set up in my trunk right now. I bet there aren't very many people on here hitting 143.5 legal with 1 15 in their trunk on 600 watts RMS. My sub is very underpowered (sub RMS is 3k).
