I'm personally skeptical that there is any useful response in these regions, at least not in the front door speakers on my LX. They rolloff well before 40.![]()
Toyota JBL System Specs
Well I've been installing Rattletrap by Fatmat (anti-vibration material, similar to dynamat) in all my doors and tailgate (another story in itself) and decided to finally get a bead on the system specs for the JBL system using my multimeter. I've been thinking about replacing the stock speakers...www.toyotanation.com
This is specs for a Highlander JBL system. Different but you can extrapolate. Like i wrote above, JBL wattage is PEAK. RMS/continuous rating is probably around half.
The 6x9s can go down to around 28 Hz…but probably only useful to about 30-40 Hz. The cargo subwoofer and front door 6x9 speakers represent the BASS of the system.
Still think the stock ML stereo sounded good, if a bit bass light. And I didn't know it was bass light until I added the bass, if that makes any sense.
I'll go look at the DSP software and see if it'll output a xover report.
