SPL Dynamics

[WildChild]

I've just been given a set of SPL Dynamics, work perfectly, i've got 2x 180W and 2x150W + tweeters, didn't think much of these till i saw the "Which Brands" thread.. He installed them in his Fiat Panda, but he's getting a new car (looking at a few VW's as he's impressed with mine..)

anyway i fixed his PC for him and gave him a new Antec case and some extra upgrades for free i had lying around inreturn he gave me these SPL Dynamics..

Now i know for a fact that these speakers are fantastic as they sounded mint in his car and that was with a 15Wx4 unbranded headunit and cheap wire..

How would i go about installing these in my door?

i currently have 2 6x9s in the parcel shelf, which do the job fine for radio e.t.c

seems a shame to waste these, either use them or sell them?

could anyone give me some advice on how to install them and also what they are perhaps worth?
