Marine Amp question - NOT for boat

Hey guys, I hope this is the right spot. The question is in regards to marine grade audio, and I know there are some absolute guru's on here.

I have a 1970 FJ40 and need some creative guidance. I have about 9inX12in in the glove box where I want to mount a marine grade amp. I need it to power 2 6X9's effectively with only an ipod as input. I need it to work, but not be too expensive as I am not interested in being too bummed out if someone yanks it if I happen to be at the beach or something. I have speakers under control for the most part. I'm looking for mid quality sound at best.

I'm having a hard time finding something that will fit and ran accross this little gadget. I understand it is not pushing out QUALITY watts or the QTY it says. What do you think?
