Id go listen to as many brands as you can, let your ears, and wallet decide.

 

Some have changed out their factory speakers for aftermarket with mild success. The issue you will run into is the better the speaker the more demand you will have for greater amplification. Being somewhat dramatic you could throw more power to your stock speakers with an aftermarket amp and achieve better sound than throwing "way" better speakers on stock amplification. Great speakers with low amplification with distort quick. Stock speakers on more power wouldn't last however. But yes you can find better speakers to run on stock amplification, just not much better due to power constraints as I mentioned. Honestly, grab some $250 6.5 components and some coaxials for the rear and throw on a couple hundred dollar 4 channel amp and rock out. I'd eventually if not at the same time find a subwoofer and amp to balance the system out.

Hertz/Morel/JL Audio are good but so many on the market..all depends on your budget.

 

I’ve been down this road so many times. Over and over I convince myself that better speakers will be good enough and then I’ll add an aftermarket amp and sub “later”. 20 years ago that worked-not anymore. Now I only want a “little better” but it’s $2000 or nothing just to get started.
Shane803 is giving you really good advice. Bruce with HushCarAudio can give you great pricing and won’t steer you wrong either. They are both spot on.

FWIW, I’m replacing door speakers and adding two 10” subs. I’ll have a 6 channel amp powering the front and rear speakers and a mono amp for the subs. I’ll have an entry level dsp and the zen audio a2b to integrate into my B&O 8-speaker system. That’s a little over $3k and none of the individual items are worth bragging about. They’re simply the best bank for the buck and will drastically improve the sound once all installed and I’ll have to do the install myself.

Last weekend I had time to apply the sound deadener and replace the door speakers. Still on the stock amp and stock sub. It’s disheartening how it currently sounds. If anything, it’s more “muddy” because of the stock equalizer settings within the system and the lower sensitivity of the speakers. If you’re going to upgrade slowly, be prepared for disappointment until you’re able to follow the advice from this thread.

 

Coming in a little hot there, don't you think? Nobody said anything about anyone being unable to follow advice, lol. Keep in mind, you might have different expectations and priorities too. Your input is appreciated though.

 

I don't think he was trying to come in hot. I think he was speaking of the disappointment of upgrading to better, but more power-hungry speakers without being able to add an amp. I don't think it would be great to add ~$500 worth of better speakers that didn't sound much better (if at all) being powered by the stock amp.

However, one can find some pretty decent speakers with lower impedance that should sound better than stock. If you have a reputable car audio shop in your town, they would be worth a visit. The guys who do it for a living are always good to hit up for advice, as they have most likely done a few 150's.

 

Apologies for any offense. Only meant to express empathy for being at exactly the same place many times in my past and regretting some of my own decisions. And to add support to some of the advice here. YMMV. Only best wishes for your project.

 

Eh, one of those days here in upstate NY, the air temp started out at -10 this morning and the people throughout the day made it seem colder, lol. Maybe I was ready for your intentions to be negative when it appears that wasn't the case. My apologies for overreacting, thanks for helping. I will look into adding more power before dumping too much into speakers with unrealistic expectations.

 

Im planning to upgrade mine when it comes in which speakers for the front and back and how are you installing the sub enclosure along with what subs did you use along with amp/dsp. I'm already set on getting the Zena2b

 

I emailed Bruce at HushCarAudio. (Forum member) I gave him my budget and goals…and then changed my mind twice. He answered every question and helped me work through it. His pricing is also excellent. 100% recommend.

I needed to keep my under seat rear storage. Huge limiting factor. I built a sealed box for behind the seat similar to MTIs design. Already had two shallow JL 10”s for it from a previous build. (Neighbor has the JL stealth box with the one 13.5” under the seat and it’s incredible.)

Morel 6.5 coaxials for the rear fill, Morel 6.5 components for the front. Audio Control LC 6.1200 amp driving all of those. Audio Control LC 1.800 driving the two shallow subs. Dayton 408 DSP. And the NavTV a2b.

Once I had the door speakers installed I hooked up the subs to test and it was exactly what I wanted. Taking the subs and both amps out to build a new amp rack leaves me with new door speakers and the stock amp and sub. Ugh.

Serious audio guys would call my new set up an entry-level system and they’d be right. It’s so much better than the 8-speaker BO system though. Absolutely worth the price of admission.

 

The system you mentioned is anything but entry level. Your sound if tuned properly with the DSP should be amazing. Where the systems change the most is when we pick how much bass we want. Do I want the space under the seat? Do I want to want an under seat enclosure? Do I want to remove the rear 40/60/100? Do I want to replace my alternator, Big 3 upgrade, run a Lithium battery? Do I want to keep my seat and do a blow-through and put the box in the bed. How much do I want to spend? I've done all them at one point or another. I've currently got a Gately enclosure with four 8" Gately Relentless subs. I'd put these against anything else on the market in terms of an under seat box. Would have never thought 8's could move air like this. I however want more...so I'm pulling the seats for a custom enclosure with two Sundown Audio Zv5 12's. I may get tired of it and revert back one day, who knows. The biggest problem I have had is throwing money in different directions instead of knowing what I wanted and going there in a straight path.
