I have 2 power hx2 10's the cone is frozen in on one and the other just makes a ton of noise. I', not sure what they are worth i need some input i need them gone. These are the 1000w rms ones not the cheap punch ones.
you'll need a y-pipe to be made. im sure they sell kits. The best thing to do is intake exhaust and have a ls1 shop tune it. Your motor is almost the same concept as mine. and ive been working on them for years.
Is the check engine light on if so have someone scan it and get the codes. I would start with a tune up as well or could possibly be a vacuum leak. Open the hood listen to see if you hear hissing. You would be surprised how much a small vacuum leak can effect the idling.
I jsut finished building a 6 Cubic ft. box for the Team Rockford 12 How many Hz should i be tuning to and what size ports should i be putting in.... Im lost when it comes to tuning an enclosure.
