Ok, here's my take on your setup. Please don't take my comments the wrong way, I'm just going to be honest and try to help you improve your setup. First off, nice subs, I have 2 10 w3's myself. So your okay in that department, but I don't like the plans for the front setup. You have the r19's which are silk dome and and a pretty good tweeter but to pair that up with the tweeter that's in the pioneer 6x8 is not a good idea. I would scrap the 6x8's and pick up a decent pair of 6 1/2 in. mids to pair up with the r19's. I just got a set of vifa's that some people on here recommended and they're lovely. I think they were about 75.00 or so for the pair including shipping. You can sell those 6x8's and you'll have half the money for the 6 1/2's. However, you WILL need an amp if you decide on these vifas as they are power hungery. You mentioned using an amp for the fronts, do you have it allready and if so, what kind? If not check out ebay and you can probably pick up a decent 2 channel for 100.00 or less. I would still run the back speakers you have now off the HU. Also it would help if you picked up a pair of crossovers for the front set. The setup I'm describing will be absolutely no comparison to what you have originally planned and I think you'll be quite happy if you go this way. You have some good equiptment, and there'e no reason not to finish the job right. If you need anymore advice I'll be happy to help and I'm sure some others on here will chime in as there are some very knowledgable peeps on here. BTW, if your interested in the vifas let me know and I'll find you the link.
