The peak power doesnt matter, just try and match the rms of the sub to the rms output of your amp.

Alright, thanks for the quick replies.

I was going to run 2 18" Qs off 1000 watts to each. (The amp is said to do 2000w @ 1ohm, but it could do a little more. It's a Lighting Audio if it matters.) Do you think the Qs with no options would work fine on this amount of power? I probably wont upgrade my amp to anything bigger, unless I go with a whole new setup.

I dont mean to jack your thread or make a new thread for basically the same topic, so i'm basically in the same boat as the other guy. Im wanting to go with the same setup but I only have 2000 watts to work with. Do you think this would be enough for the BLs with no options or should I go with the Qs with (whatever) options?

Between two 15" CVXs or two FI Qs. Do you think that off the same power, 1000 watts each, both in a ported box in the same vehicle, (tahoe), which do you think could get louder? I know it depends on the install but they're basically going in the same setup. Which do you think would get louder and sound better doing it? I think it would probably be the Q but I havent heard either.

I know i didnt cover every variable but there basically going in the same setup.

Im installing this unit in a 2001 tahoe. Im having trouble with it. I bought an install kit, i think the # is 99-3002. But i think it might need a mounting sleeve for it. Has anyone had any experience installing Premier headunits, im not sure exactly what i need?

Well, i got it from onlinecarstereo.com. Are you saying that the 490ib has to have the mounting sleeve or that the models that do have to have it usually come with it?
