Help understanding ohm for speaker replacement

[lashlee]

I hate to break it to you, but the head unit with 100% certainty will over heat if played at near full volume for approximately 35-40 minutes. I have the exact Kicker replacement speakers the author is speaking about and the head unit will come up with a prompt at that time that states “Amplifier too hot. Adjusting volume.” At that point it’s done for about 5-6 minutes before the sound will turn back on. This is for the reason of the 4ohm producing more power, in turn heating up the unit; further exacerbated in the winter with the heat on or when it’s hot with top off.

I solved the issue by buying and installing the Alpine WRA-i509. It now sounds way better than before and never over heats. If you’re wanting to keep the original head unit, you may be able to find 8ohm coaxial speakers. I like my Kicker bundle, however the front 3.5” dash speakers are not worth the money in the bundle. While louder, they are extremely sharp. I am going to swap out my dash speakers with Terra Acoustics 8ohm setup and will do a write up when done.

Unless you have rear passengers, I wouldn’t splurge for the soundbar replacements either if I had to do it over again.

If you are playing a H/U at nearly full volume, you are outside of the expected "normal" volume levels of the average listener. That is what I would consider as a result of improper usage and less of an equipment issue. Even though you "fixed" the issue by replacing the H/U, you really need a more powerful amp if you want that sort of volume for an extended listening session.

My statement of being excessive was referring to the statement Nukem made that it may catch fire. Most electronics will have protections built into them, which you proved, that will reduce volume to keep them from burning up. Heat is the enemy of all electronics, like you mentioned, and the cooler you can keep components, the longer they will last.

“Fixed”…as a former MECP First-class installer and current Journeyman Electrician, the issue was fixed by installing a head unit designed for a 4 ohm speaker load. I deal with making circuits daily. When I say it’s fixed, there’s an actual level of professional experience to back it up. Thanks for your opinion though.

As a fellow past MECP installer, SQ competitor from '96 -'08, and current IBEW member, I'm sorry if you were upset by my statement. I agree that the H/U designed for a 4 ohm load is one way to fix it, an amplifier would do the same, and may be a better option in the long run.
