Looking to improve the sound of my "new" Aveo

[ExtraElectric]

So I just bought a 2009 Aveo5. I've been spoiled because the car I've been driving for the past 8 years (2002 Jeep Liberty) had their "premium" sound system installed. It wasn't amazing, but it was better than most cars stock. On top of that, one of the rear speakers in the Aveo sounds like it's blown so I definitely need to fix it soon.

First of all, I'll say that I'm not looking to deck this thing out. I don't really have the money or the need. So I'd like to stay away from adding anything extra like amps and subs. I'd like to try to do it all myself, which will probably be challenging but doable. But that means I'd like to stick to replacing stock items. So I was thinking of getting a new HU and front and rear speakers.

Anyway, the main question I want to ask is about the rear speakers. I've been reading the forums and I've found a lot about the front door speakers (get shallow 6.5", spacer, etc), but I've found relatively little about the ones in the hatch. Crutchfield says to put like 3.5" speakers in there, but I know the ones in there are 4x6. But will any 4x6 fit in there pretty easily? I'd like to stay away from anything more than very minor modifications because I don't want to screw anything up. And is there a guide somewhere about how to get to them? It seems like it would be pretty easy, but I didn't see any screws and I don't want to go prying at random pieces of plastic.

Oh, one other thing. Do most 2009 Aveos have tweeters? Mine does, but I've seen almost no topics about tweeters and I was curious. Are those pretty much one size? If I'm going to the trouble to replace the rest of the speakers, I figure I might as well get some nice replacements for those too.

Thanks for any help/advice you guys can offer! I'm totally new to car modifications, so please be patient with me

If you do a search you find how to get the pillar trims off. You can see how I add my Frt. tweeters then up graded them on my Cardomain Pg.9 You will have to buy speaker Connectors if you do not want to cut your speaker wiring. The 4x6 screws go on the under side . You will have to pop up the inner trim clips on the fuzz plastic trim to get to the screws, or pry it out of the way. Have fun. Oh just about any 4x6 will fit. I run cap on the 4x6's so all most no bass goes to them piggy back some 6-1/2's back there

I was told that the size of the Aveo speakers won't put out quality sound w/o a sub and amp, but I'm not entirely sure. I'm lookinf for a solution myself

Subs aren't for quality without bigger powered speakers all around. I'm running 6.5"s in the door and 6x9s in the rear hatch powered by a Kenwood 600w amp. No subs for me, take up too much space and weight

Thanks for the input! Do I need to buy connectors for the speakers in the hatch or just for the tweeters? I took a quick peek behind the felt and it looked like the speaker wires were connected to the car wires by something that clipped together.

Yea I believe they clip together

I cut the factory connectors and spliced on some spades... I'm still having an internal debate about whether or not I want a sub... the sound really could use some added bass with the powered speakers... but my amp is way too powerful for "a little bass"

[festersays]

600 watts will be plenty for a little bass! Even the littlest bit will do ya' good, Pickles.

As for adding sound quality, any aftermarket speaker could defiantly use some extra power. Luckily for the OP, he can get that from the aftermarket HU.

My advice: get some 2 or 3 way speakers for the front, absolutely as big as you can fit in the door. Do yourself a favor and upgrade from the 4x6's That size speaker could probably do nothing in terms of reproducing any kind of bass, which would be a nice touch since you're trying to bump up SQ a little bit.

^the 600w amp is for my speakers... I have a 500w rms amp laying around but it is too powerful and overpowers the speakers
