Some found it to work, some found that it made it sound like crud. All say it got "louder", but some say that the factory EQing got messed up.....however, that could have been on later versions.

Do a serch for "nitro amp" and you will find posts on it.

panthermark You can change speakers, but you are still limited by the amp on the premium system.

The front speakers are at least full channel speakers, so if you are going to change one pair, change those. BUT, the amp is 2 ohms, so you won't be doing yourself any favors by putting in good 4 ohm aftermarket speakers without adding a new amp.

The soundbar speakers are quieter (compared to the front speakers), and are also crossed over. It just sucks that you can't adjust the rear gain or crossover frequencies on the factory amp.

When I was swapping an polyfilling my speakers, I left the sub unhooked to I could listed to each of the front speakers by themselves (without bass from the sub).

The sound bar speakers sound like the have a low pass filter on them at a very low slope (maybe 120hz at 3db?) and are quite a bit quieter than the front speakers at the same volume level.

It is one of the reasons why so many people were trying the amps out of Nitro's. The rear speakers outputs were not capped.

I don't think it limits the volume to fix issues with vibrations, it limits volume by virtue of the amp being an anaemic waste of space.

I don't see that it makes a difference; again, the amp is the limiting factor, not the speakers. The stock speakers aren't the greatest units and you will see an improvement in sound quality when you replace them, but new speakers won't really sing until they're being driven properly.

I would like to do this in stages (for example, replace the speakers in the roll bar or front dash, etc.) but wasn't sure what would be the biggest bang for my buck. I called crutchfield and they recommended that I replace the roll bar speakers with a pair of Polk Audio db651s first along with the dash. I questioned them about some of the posts I have read concerning the rear speakers being limited in the amount of volume\power that is being supplied to them and they were unaware of this and found nothing in their documents. They still insisted this would be the first thing to replace given that I want to do it in stages. I tried changing the fader from front to back on the factory unit and did notice the volume difference. I guess my question is what would you guys replace first to get the most noticeable difference? Keep in mind that I am on a budget and want to replace a few things at a time with the end goal of replacing it all at some point. Would you start out with replacing the speakers in the roll bar? Or do the front dash? Or would you replace the head unit altogether first? Any suggestion?
Changing speakers first will improve sound quality, but it won't give you any more volume - the amp is the limiting factor there. I went head unit, then speakers, then amp and sub, but that's mainly because I had the crappiest 130 without the connectivity option; I don't think there's a "right" order in which to do it. Soundbar speakers, dash speakers, amp and sub, head unit would probably be the most logical order.

Motorjock603 I added an Alpine PDX-5 amp, line out converter and 10 inch Image Dynamics sub in a box to mine. I already had both from a previous vehicle. The amp runs the front and rear speakers as well as the sub and the factory speakers sound so much better. I'm keeping the factory head unit because I don't want to have to worry about theft. I'll probably replace the sound bar speakers with the Kicker ones. The reviews seem to be really good. I'd like to do some Focal components in the front but they're so doggone expensive. You should get out to some local shops and listen to some speakers before you buy. Good luck!
