fi sp4 opinions?

[Justin braaapp]

Hey guys I have a chance to get an sp4 15 for a pretty good deal. 400 bucks with 10 gauge wire for the sub, a run of 0 gauge wire, and two jbl 12's just for free (which I would obviously just sell on craigs) just wanted to know what you guys thought of the sp4? They look pretty well built and have some pretty insane videos on youtube. It would be going in a 99 chevy silverado ext cab and powered by a nendo bc 3500. Any feedback you guys could give me about these would be appreciated thanks!

your gunna for sure have to upgrade everything; your amps, alt, batteries, and speakers to get even near the full potential of the sub. keep that in mind, it gets stupid expensive.

I have an xs d3400, with 3 runs of 0 gauge from my front batt to it and big 3 upgrade. not planning on an alternator now and how would i need to upgrade my amp?
