Ok, here's the deal, I recently bought a used truck (99 Dodge Dakota X-cab). It looks to my untrained eye that the previous owner had a fairly decent sound system setup. However, upon selling the truck some essential parts were removed. There is a pioneer cd player/head unit, and 4 pioneer speakers (2 in the doors and 2 in the rear). It appears that all of this was routed to an amp either under the driver seat, or under the rear seat. There is a pair of green rca cables under the rear seat (I assume this is coming from the cd player/reciever), a bundle of 8 wires under the driver seat (I assume these go to the speakers), and two wires running from under the middle of the dash to under the driver seat (I assume these are for power). There are also two ground wires attached to the driver and passanger seats, and I found a loose rca patch cable with 4 ends on each side, along with bits of loose wire under the driver seat. I'm guessing there were two amps and a sub which were removed, does this sound about right? Now this may make some of you cringe, but my requirements for car audio have previously not made me take the jump up from the factory system. I did replace my tape deck with a cd player in my previous car, but that is the extent of experience I have. The head unit is a Pioneer DEH-2300 which has 50w X 4 of power, this would seem to be plenty of power for my needs, how feasible would it be to re-run the speaker wires back to the receiver and be done? Is this something fairly straightforward to do? My other option would be to get a decent, inexpensive amp off of ebay...I'm leaning towards this since all the wires are already run, and all I have to do is plug the thing in. If I go this route, what are some decent sounding, inexpensive brands/models of amps? If I go this route, will I really need to replace the sub also? I appreciate good sound, but I don't have alot of money to sink into this project...if I can get the system back working and sounding better than the factory system I'll be pleased. Any advice?
