What People Are Saying

Rated 5 out of 5 by from Most bang for the buck. This thing rocks. No distortion at any level. Will shake pictures off the walls with ease. If you have old windows like I do, they will rattle to the point you will worry about breaking them. I dare anyone to try to compare against this system dollar for dollar. Give it a little time to break in from new and it will sound much louder with low hitting bass tones.

Rated 5 out of 5 by from Fantastic! Bought this about two months ago absolutely no regrets bass hits hard mids and highs very clear as well and nothing is muffled out at any volume on this. Talk of the party and all my friends are looking into getting one of these or a similar lg speaker system. Bluetooth connects very easily and does not need to be powered on when connecting to it.

Rated 5 out of 5 by from Exponetial Audio System I have reviewed everything in this manual from beginning to end. I have never seen an audio system with so many options. It's definitely got everything you could possibly wish for in an audio system. C'mon 3500 watts max output. You'll definitely be in the professional arena. The LG name behind it your talking lasting quality.Remote control offers every option. I've had two different model LG phones. Both phones were of excellent quality. I know anything else they make would be of this professional quality!

Could this system be compatible to hook up to a car? Like would there be enough power coming from the battery? Would you need a power inverter?? Plz help lol. I think it'd work but don't wanna get it and it not :)

Asked by: Mike 247
A car battery outputs 12 V DC and the LG 3500W Hi-Fi Entertainment System with Bluetooth® Connectivity, Model # CJ98 has to be plugged into an AC voltage outlet rated at 110 V / 15 A or 230 V / 15 A. You can visit a Consumer Electronic Retailer that sells car accessories to inquire about an inverter...^IFV

How many can you party link?

Asked by: Jaydies
The Wireless Party Link Connection feature on the LG 3500W Hi-Fi Entertainment System with Bluetooth® Connectivity, Model # CJ98 is compatible with LG products that support that feature. It establishes one unit as the master unit and the other as the slave unit. When the units are successfully connected, “Slave Device Name CONNECTED” appears in the MASTER unit, and “CONNECTED TO Master Device Name” appears in the SLAVE unit and changes to SLAVE soon...^IFV
