I was looking to just drop in a better set of speakers now and then a head unit later on. At Circuit City then said with the factory setup I can't just drop in a different sub in place of the Infinity factory one. They said I would need a new amp and other stuff. Are they right? Plus which speakers can easily replace the front and rear factory ones? I would prefer to attemopt this myself. Thanks.

 

to put a deck make sure you get the mitah cable otherwise it won't work...speakers are just a swap in...as for the sub i don't think you really can put a diff one in place that will sound better as the factory amp is rather small and not enough to bump a larger sub...

 

So basically I have to ditch the factory amp and get one to drive the sub and new spealers I decide to get. Just not really into the audio scene and want my **** to be loud and clear with minimum dough spent.

 

just get a deck first, you won't believe how much the system wakes up, then do speakers and finally change out the amp and sub if need be

 

do what i did i bought some pioneer premier kevlar speakers and a 480 watt amp and that's it i'm going off the stock head unit. I think it sounds great, it's not a competition sound system but it get's loud as Hell...

 

You never want to run an aftermarket sub on a stock amp. The box will most likely not have the correct airspace. Also, they are usually rated at different impedances. Most basic aftermarket subs are 2 or 4 ohm. You can then get 2 or 4 ohm DVC (Dual Voice Coils) which you can rewire into configurations of from 1-8 ohms. On top of that you can get some speakers in different ohms ratings from 0.5 to 16 ohms based on how many you have and are wiring together to get a specific impedance to match to an amp. Sorry, I'll quit there so I don't get too confusing.

Anyways, to spend minimal $$$, just go for a simple 10 or 12 inch subwoofer (plus box) and a mono or 2 channel amp. A simple aftermarket stereo and basic replacement door speakers should be all you need. You don't even have to replace the rears to save a few extra bucks. You do not have to power your aftermarket door speakers with an aftermarket amp if you don't go and try to get some high end components. Some simple coaxials will work off the stock unit or aftermarket unit fine. Granted you will not have the most superior SQ (sound quality) but you will have better sound than stock.

If this is your first time with installing audio, be patient and follow directions. Get a friend and make a day out of it. It can be very rewarding to do yourself and you will find that it is not that hard if you are simply replacing stock components and hooking up an amp.

 

SSL=Not worth it. Build your own system. Cheaper, Better SQ, and You Choose the Components you want!

 

Actually, it was worth it for the non-blue seats, HID headlights, and sunroof. Unfortunately, in 2005 it was an all or nothing package.

 

^^umm not too sure on ur statement, but my 05Evo has HIDs, but doesnt have sub, sunroof, nor leather. I dont care, because the most important part was the HIDs!

 

Unless you have an MR, your '05 won't have factory HIDs unless you have the SSL package.

I agree with the above. Start with a decent aftermarket HU and the stock speakers will sound MUCH better. I did that and I'm now getting together my amps and speakers so I can upgrade the rest in one big complete step. I'm not going to bother with just adding an amp and sub, or amping the stock speakers.
