I tried to search a little and came up with nothing.

What's the specs for the 5th gen entune? I just replaced the front, rear, and cargo speakers with cheap Kickers and started to get curious on how many watts is the radio capable of pumping.

Of course you can call Toyota to find out. However most stock radios usually put out about 20-ish watts of rms (that's true power) per channel. Not sure if you got 2 or 4 ohm impedance on your speakers when you bought them, but that won't make that much of a difference because even if it's off, having low wattage won't really affect it. You can also call Car Audio Stereo - Car Subwoofers - Car Amplifiers and Speakers they are a great online car audio dealer, with great prices-tou can haggle with them a little too. They'll be able to answer these questions, they've got great tech support.

For some reason it didn't show the website. It's Car Audio Stereo - Car Subwoofers - Car Amplifiers and Speakers to

16-20 watts is normal for an OEM stereo. Rear doors and tailgate are run in series off the rear channels of the stereo so cut that in half. There are only 2 rear channels driving 4 speakers. Hope you replaced the dash speakers also, that'll make more of a difference than anything else.

I think you mean series parallel, the front dash and doors are series parallel as well.

No, they are all series, not series parallel. Series parallel is when you have say 4 speakers. 2 sets of 2, you series 2 speakers with each other and they parallel the 2 pairs. Hope that makes sense lol. You can't run series parallel with only 2 speakers.

Right, that is what I'm saying. The front channels are the dash speakers and the door speakers, 4 total. The rear channels are the rear doors and lift gate, 4 total. There are only 4 pairs of speaker wire coming out of the head unit ie. LF (all +/-), RF, LR, RR. The 4R has 8 speakers total.

I know how it works. There is no series parallel though, just series for the total of 8 speakers as you stated. Rear doors and tailgate are series on the 2 rear channels, dash and doors are series on the 2 front channels.

Ok, not trying to be argumentative, just following your logic. How is the impedance of the speakers in series compensated for then?

What do you mean? Asking that seriously, I don't want to argue either, I have better things to do. I've been in the audio industry for 20 years and I'm sure I can explain anything you may want to know. Series turns a pair of 4 ohm speakers into a single 8 ohm load. Parallel turns a pair of 4 ohm speakers into a single 2 ohm load. You can do this is any speaker. Take a paid of 8 ohm speakers and run them in parallel for a single 4 ohm load, and pair of 8 ohm speakers in series for a 16 ohm load. The possibilities are literally endless. The higher the impedance (resistance), the cleaner and cooler the amp will run, it will pull less current also, however output power is compromised. The lower the impedance, the more power the amp will produce however it will run hotter, pull more current, clarity is compromised, and in some cases the integrity of the amp is compromised.

Fair enough, I will leave it with this. The head unit sees 8 Ohms due to the 4 Ohm speakers in series, which in turn, cuts the output power of the head unit. With this said, a simple (not really simple) re wire of the speakers so the head unit sees 4 Ohms instead of 8 Ohms would increase the output of the stock head unit for relatively cheap other than someone's time. Correct?

That is partly incorrect assuming the stock speakers are 4 ohms each. If the stock speakers are 4 ohms each, running them in series will give you 8 ohms, you're correct there. If you were to rewire them and run them in parallel, the stereo would see a 2 ohm load on each channel. This would cause the stereo to run much hotter than it was designed to run, possibly overheat the internal amp, possibly damage the internal amp. A pair of 4 ohm speakers in series provides an 8 ohm load, a pair of 4 ohm speakers in parallel provides a 2 ohm load.

The front dash and front door speakers are series-parallel, the the rear door and rear hatch speakers are series-only, just look at a wiring schematic, or unplug your rear door speaker and the hatch speaker will stop working.

I haven't ohmed the stock ones, but they are noticeably quieter than the fronts, so I assume they're 4 ohms, for a circuit total of 8 ohms.

The Entune headunit is definitely compensating with a built in equalizer tune. I've been waiting for TacoTunes or someone to post a youtube vid with a white sound analysis of what it's actually kicking out. The front is receiving most of the bass, and the stock speakers are pitiful. The bass response is very tapered as volume is increased, I assume to keep the stock speakers from clipping.

DSP amps, decent speakers, and a sub run from the front input are the cure, with each speaker output on its own channel (no series-parallel or series).

Thank you, we were both correct on one end. Makes sense now.

Kind of odd that all this is lumped into one area. Most sites break down by category like audio, suspension, lighting ect... op do you have party mode and does that make a difference with the aftermarket setup?
