I think you will be better off adding an amp to your system.

I guess it depends on how much effort and money you were planning to spend on this. Harvey (harveypnp@comcast.net) sells a kit that can be wired to either the stock headunit or a stock 6-channel amp. I found an inexpensive amp on eBay and it was plug and play. I found this to be a cost-effective solution.

I'm sure that there are amps that sound better than the stock unit, but the cost of the amp and the installation will be higher than OEM unless you have the skill to do it yourself. Insite's recommendation on the wiring is probably workable, but it seems like 18 watts would be somewhat low to drive that many speakers. I'm not an expert on the subject so I could be wrong.

Good luck.
