Re: good sounding speakers 6x9s
Definitely go marine, but try to match them up with your radio/amplifier as much as possible. Oval speakers aren't as efficient as round ones, so if you're a little short on power, you might not have the bass response that you want. I'm not talking ghetto bass thumping, just a nice full sound at low-mid volume. Look at frequency response too. Needs to be at least 60 on the bottom end and 12000 or so on top. Some show numbers like 30-20,000 but that's more than your ears can deal with (at least on the high end...but your dog might like it) so they're not really worth any extra money, IMO.
