I just bought the same thing from the same company last week. They're a great company and I'd recommend them to anyone. I don't have it wired up entirely as I'm working on custom mounts for the component speakers in the front doors (I have a 94 pickup extended cab).
The power it's running off now is run through my aux fuse box (I know... bad) so I have yet to experience it's full capabilities. But right now, it'll give enough bass to make the speedo needle bounce, which is enough for me.
Everyone is right when they say that it won't produce bass as good as a sealed box and seperate amp. I know because I've been there. I spent $550 on 2 DEI Pro 10" subs in a sealed box, powered by a 300 watt DEI amp that I had in my honda accord. It was great bass and I miss it, but it was way too much for my truck.
I'm going to finish setting up my system and if I'm still not happy with the bass, I'll send the Basslink back and get the box, sub, and amp. I like the fact that it's an all in 1 package and if I need to move it, I can do so easily. But it's all about the quality, so if it doesnt thump like I want it, it's gone. I can let you know what I do when I finish everything up but that's going to be at least a week. But it'll make for a strange comparison because I have a pickup and you have a 4Runner.
Reapur- what were your final settings on the amp? I'm still trying to find the best combo with the gain, cutoff frequency, and bass boost. Does wiring the remote make it any louder?
