You can hook up a Basslink to anything with a signal. It has to be the easiest way to get sub-bass in your car.
I bought one for my girlfriend, because I end up driving us around in her SUV quite a bit. I took it out, because it sounds like sh*t. I have it sitting in my closet, and was going to give it to my little brother when he gets his first car in a few months, but the thing sucks so bad I can't bring myself to even give it away to someone I know, so I'm thinking of eBaying it. But - I dont know you, so I could sell it to you. It's a Basslink X, with the remote bass control. Only a month or so of listening on it. You can have it for $150 + shipping if you want it, but since you've come here for advice - I'd advise you to invest in a low-priced sub-amp combo. IMO a 10" Kicker comp with 150w to it sounds twice as nice as a Basslink. You should be able to do that combo for $200 - easy.
But if you're set on the Basslink, e-mail me and I'll give you the details on hooking it up.
