Ive read a lot of threads on here about car stereos and it seems that most people say that the stock amp dont sound good with aftermarket speakers. You could hook them up and try them out tho.

All things considered, our stock systems arent too bad. What throws things off is the fact on the premium systems they used 2ohm speakers. Since most aftermarket speakers are 4ohms thats where the "problem" comes in. Upgrading the speakers only will result in an upgrade based on the sound but you wont get the same volume due to the increased resistance. Not only that, but you'll still have to deal with the integrated bass inhibit once the volume goes above a certain level. I highly suggest replacing the head unit when you replace the speakers, or an aftermarket amp and bypass the factory one.

To bypass factory amp on a 00-01, installing aftermarket and running new wires to speakers, can i just unplug it or do I need the bypass for it. I will also maintain the factory headunit , for now.

Thanks.

If you're keeping the stock head unit, get the bypass plug

If you're keeping the stock headunit, don't bother with aftermarket speakers, they won't sound as good as the stock ones off the stock headunit.

It probably will make it even worse if you go and bypass the stock amp also.

Well, I blew my factory speakers and I have already replaced with Infinity Kappa's. The sound quality is not much better, but like with a nice set of headphones you can hear more. Anyways all I need to do is add the amp and I already have run my power wire. I just do not want to want to do work twice, that's all. I will replace my H/U when I do my gauges and HVAC controls.

That's not been my experience. When I did this, the aftermarket speakers sounded better but they just didn't get as loud. Of course it all depends on speaker selection....I wouldn't expect the speakers listed in the OP to be much of an upgrade.

Am I required to use the bypass or can I just unplug it?

are you keeping the stock headunit or no? If not and adding an amp then you can just unplug it
