If you feed a 300W speaker 150W RMS, you're not going to damage it. The damage comes when you try to make that 150W RMS amp push 300W by turning up the gain all the way, in which clipping will happen. Coaxial speakers are usually rated for "Recommended amplifier size of: # - #W RMS"

I don't know jack about car speakers but I have been doing audio work for over 20 years. A speaker is damaged thermally or mechanically meaning the speaker coil is melting because of too much heat or the speaker itself is physically traveling past what it's designed, going past it's excursion limit, because of too much power and also because of the enclosure it's built in. This can happen if you are trying to push a frequency the speaker can not handle such as feeding a tweeter a signal that is intended for a subwoofer. Although you can "clip" a signal with a lower powered amp, I have never personally seen it do any damage to a speaker and is debated among audiophiles. So while you may be able to damage some components with a power under the rating, the likelihood is very small. You would almost have to "try" to do it. I haven't heard any components do this in the last 15 or so years but then again, I don't tinker with cheap stuff for giggles anymore either.
To me, if a tweeter sounds like it is getting blown regardless of the power present, you turn it down. Any speaker for that matter. It's usually pretty obvious when you hear a speaker bottom out or distort and common sense usually kicks in to help you out. I don't think I am going to have a problem with my speakers or the amp I am intending to use as far as being under powered in my situation. I have used the amp before and the stock power is plenty for me with hardly any volume.

Car audio is not any different than general audio, including home theater surround. If you know everything there is to know about home theater audio and setting up the audio, you pretty much have the knowledge about car audio. If you're wanting to get into reflex boxes and tuning the frequency of the box, that can take some skill and knowledge. My personal taste for car audio is component speakers rather than 2way or 3 way speakers. They have a broader spectrum to render more accurate sound(s) than 2way/3way systems. The speakers put out the same frequencies as general audio do. In fact, if you wanted, you can even take the car audio and use it for home theater, and will sound just as good. Getting into your car and taking apart the stuff within your car (e.g. door panels, carpet, etc.) that can take alot of time, though.

CDT makes some really nice affordable 5.25 coax sets that last forever. Had a pair in my s10. Things took a beating and never died on me. The classic series is what i had.
Car audio once you get to a certain level is completly different then home audio. Once you get into competition style audio its a whole different world. Tuning frequency, Resonant frequency and all come into play. If going for sound quality alignment and all comes into play also. Most is vehicle specific.

False. The second you turn the volume down technically the speaker is "under powered". The speaker will not see full power at all times. Power to the speaker continues to fluctuate with volume and tones. It does not see a constant power at all times. Throw a clamp meter on an amplifier while playing any given song. Power is never constant.

Well, when you put it that way, yeah..., car audio has a huge difference, especially with the bass. What I stated above, car audio is doable for home audio (mostly for those that are on a budget or doing some physical/audio tests) and the majority of consumers won't even tell a difference and/or even care about it. But it does work.

158.6db sealed legal @37hz Yeah, no... I won't be getting anywhere close to that. At all. Reference level (85db) in my home is plenty. I can get down to 16hz but that's for movies. I just want this jeep to sound decent. I don't need to bump and the only person intended to hear my music is me so I don't need the crazy power.

Yeah, agreed. That kind of sound is to prove to the world that you have sound while not getting stopped by the cops.

That is a myth. Here is some info on what actually causes damage to speakers. http://www.bcae1.com/2ltlpwr.htm It mentions clipping at lower power as one of the main culprits to damaging a driver... The best way to avoid that is to tune your system with something like this: I had one of those for my last set-up. It was really nice to get the maximum output of my system, knowing it wasn't damaging my drivers at full volume. My Pioneer unit didn't clip until 61/62 volume. I tuned my system at 60/62 with the SMD DD-1 and I used the sound quality tracks, rather than the power for loudness. It's definitely worth getting if you are going to run amplifiers.

really alot of people do not mess with 6th orders due to the tuning factors. It is tricky to tune a 6th order properly. 4th orders and flat walls are more popular with ported boxes being the most popular. If you are newer to tunings i would do a ported box first, if walled do a slot port. the tuning is easier. 4th order can be trickier to tune but way easier then a 6th order. My current build will be a 4th order bandpass build with 6 or 8 15's. Concrete enclosure floor, 2x4 subframe with 1.5" thick birch plys over top of that. Enclosure is all about being as rigid as possible. Flex in the box is a bad thing. I still have a lot ways to go on the enclosure. i have another 20 2x4's i will be cutting up tomorrow. ill have over 60 in this box

I look forward to seeing your build, if you share it on here. But man... nearly 160db's is just crazy. Even the enthusiast that I follow on the car audio forums barely break 150db, while only a handful break 160db. The OP is looking for tuning on an entry level system and you are over here trying to show him how to get close to world records lol

I agree with RainStryke that you should keep us informed about this build. I've done just one 6th this year. It plays well with one 12", but somewhy im not impressed. Double bass goes little bit porridge, but you can feel it coming. Also in the other end 20hz is coming out with nice wind. Main peak is around 50's. Capacity 1:2 and ports 1:5. Going to get another sub for it and turn the power on. Now this builds been disassembled and we'll see about it next year when electricity is done well. This is just my shopping cart. We'll starting friends build somewhere near this day. 4x 18" Sundown Teams with 4x Hertz MP15k's @ 18volts. Walled 6th.

Just an update, those NVX speakers came and they sound pretty good. I was a little bummed to find that someone already did some mod work and the speakers that came out were actually 6.5" Pioneers. I also found out that the one speaker was not blown but was just shorting out due to a bad wire job. The Nvx speakers sound better side by side. I checked them in and out and the nvx just sounded cleaner. I was actually surprised how much bass they had too. After checking polarity and doing some minor rewiring, I ended up pulling the stock speakers in the rear and putting the pioneers in there. I had to drill into the fiberglass panel and they only have 2 screws holding each speaker in but I just want to see how I like them for now.
I also scored a roof rack so I can get my spare tire out of the back and I think I am going to build a small ported sub box for the 10" I have. After everything is kinda in, the system sounds leaps and bounds better than it did. Thanks guys!
