There is really good advice on this forum, ive used it for many questions ive had in the past so dont let anyone sell you.. I had a 04 F150 with the box under the seat and i had first a set of Kicker CVR 10's, than a set of Memphis 10's, than the kicker CVT 10's (shallow mount) and lastly before the truck was totaled and lost to the scrap yard 2 of the alpine swr-t10's. That is 4 different sets just not the 2 the local stereo shop is trying to sell you. There are many options available so go with what suits your budget and liking the best. These guys on here with 1000 plus posts know what they are talking about and there are many good deals to be found. if your patient you will put together an awesome system.
