## Questions & Answers

**Q: why are they non returnable?**
A: Metra 72-8104 Speaker Connector for Select Toyota Vehicles
This connector does not fit Toyota Venza. Why I cannot return?

**Q: what is the average life span of these speakers?**
A: 7+ YEARS STRONG! I purchased these back in December of 2013 in college. Speakers have moved around over 10 times, but I kept the original box for moving purposes. Finally purchased a home and these still remain as my main TV speakers. I recommend this set of speakers for anyone who wants that movie theater and thrilling music experience in their own home!

**Q: How does one extend the cable of the control speaker with the 15 pin vga cable? a regular vga cable extension didn't work.**
A: The problem with most all VGA Extension cables is that they tie pins 6,7,8 and 10 to the casing (GND). This is fine for a VGA Cable, but is not desired for an extension cable. It does not work in extending the right control speaker.

Instead, go with the Amphenol Cable Extension that wires the pins straight through. 
Lengths are available in 5', 10', 15' and 25'. Just change the last two digits when looking for your desired length.
CS-DSDHD15MF0-005 Length: 5'
CS-DSDHD15MF0-010 Length: 10'
CS-DSDHD15MF0-015 Length: 15'
CS-DSDHD15MF0-025 Length: 25'

Be sure to get a Male to Female connectors.

**Q: what are the speaker and sub dimensions**
A: The sub woofer is 10" deep, 12" wide and 11" high. The speakers are 5"  wide, 5 " deep and 8" high. Meas. are aprox. Hope that helps.

## Customer Reviews

### ⭐⭐ Z623 Subs Amp is garbage
*by K***R on 10 June 2020*

Bought my Logitech Z623 last year albeit 2nd hand. Excellent when it works fine, very loud and ace for mixing etc. Trouble was a few months later the sound would flicker badly then the bass stopped altogether. I opened up the sub box and the sub is fine but the subs amp is not. Cheap shoddy circuit board within the sub box so be warned. Small speakers still work but nil bass. Bought another used sub box from europe but this has different inputs on the back of it. The uk model has dvi female on the back and german model has dvi male. Speakers i have are male so male to male will not go unless their homosexual which they arent. So had to mess around and find a female to female (lesbian) adapter. These subs are supposed to be 120w and the whole system 200w rms but the amp in it doesnt last if you have it loud.

### ⭐ So expensive!
*by M***K on 4 August 2011*

No one in their right mind would buy this at this price. There are dozens at half the price and even if they only last half the time you can get a new one at half the cost.
