2007 tundra jbl 10 spkr system

Am looking for factory specs for this system. RMS to each speaker, etc Would like to put eclipse se8365 in rear door and boston acoustic sl60 in front door. Plan to leave the head unit and amp in place for now. Also in future would like to add an amplified sub in place of the vse sub there now. Problem I have is an installer measured back speaker @ 2ohms and wants to replace them with 4ohm. Would this make a difference?

I am not looking to spend thousands, just looking to improve on what i think are poor frequency range speakers in the doors

any help appreciated,thnx

Not sure about the specific factory specs on that year Tundra (not yet anyway). A good starting point is to look on the back of the speakers and see what the ratings are (ohms and power). The factory generally sticks somewhere close to that for reliability reasons.

The "eclipse se8365" and the "boston acoustics sl60" are rated for 40 watts RMS and 80 watts RMS respectively. Those speakers will more than handled the wattage from most any factory radio. (Nice speakers, by the way!)

As far as choosing an amp in the future, a 4 channel amp with even decent power rating will more than improve over the factory sound.
Unless you're building a system for a sound off competition, a high end amp might be overkill and over-budget. (Just something to think about.)

If that factory system is in fact output to 2 ohm speakers, your best bet would be to shop around for 2 ohm speaker for the best sound. You could otherwise run into impedance-matching problems (making sure your radio and speakers match). You can get around that with an impedance-matching transformer, but that can sometimes get pricey and the sound quality might not be the best.

Let me know how it turns out.

Later.
