I only used 2 speakers to connect and will use the other 2 as spares. The system is good value for money. Installation is ok if you have little experience with mechanics (never dealt with a T-faucet). My actual problem was installing an amp under the roll bar on my 1994 Roadking. I had to make my own mount to give it a standard look. Plugged the power into the ignition and used the pocket on the windshield to hold the iPhone. No problem listening to music with 70. 4 stars for instructions. I would recommend this item
