The Polk Audio PA400.1 has been a work horse for my bass. I have it in my truck hooked up to a 10 inch dual voice coil. It definitely has enough power and fits in perfect with my set up.

I've had a PA400.1 installed in my boat for 2-3 years and it has been great. No issues.
Marine installations are a tough environment too. Does exactly what a sub amp should do - pounds the hell out of me with great deep bass. Adjustable gain, adjustable low pass filter, works great.

The only thing that I don't like about these amps is that the remote gain control (which is optional to install) uses a custom wired cable with phone jacks on the ends. It would be better if it used a more standard cable. For instance, on my boat, it barely reaches to where it needs to go, and the connectors made it hard to route the cable. In a Car or Truck, I don't think this would be any issue at all and it wasn't a big deal it's just not ideal.

Hooked it up to a Polk 10" 2 ohm db series sub, lasted only a couple hours before this funny smell and amp stopped working. Fuses didn't blow, shuts down when I turn up the volume. Had the gain only half-way, piece of junk, Made in China should have known. No customer support, they don't even know what happened!! Expected better quality from Polk Audio, go with Hifonics, Rockford, or Kicker instead. Over-rated!! 300 watts RMS at 2 ohms? My 3 year old Kenwood out performed this thing it's only rated at 200 watts max bridged, and it's not even 2 ohm stable!!
