Hello, I have this old MTX subwoofer that a friend gave me, and I don't know if I should or even can put this in my truck yet. I drive a s10 with the extended cab, and I think it fits in the back, behind the driver seat. So do you think this sub is good? Either way, I'm getting an amp for my speakers; I installed these-Amazon.com: Polk Audio DB651s Slim-Mount 6.5-Inch Coaxial Speakers (Pair): Electronics. My Kenwood head unit doesn't supply enough power to reach these speaker's peak performance. I was looking at an amp like this; Amazon.com: Pyle PLA4478 4 Ch 4000 Watts Bridgeable Mosfet Amplifier: Electronics. So what do you think?
