Line-Out Converter Specifications

Number of Channels
Each channel on an amplifier will power one speaker using a positive and negative cable. There are various types of amplifiers, each designed to power a certain number of speakers. Monoblock amplifiers, also known as single channel, are designed to power one or more subwoofers. These amplifiers often have very high power ratings. On the other hand, multi-channel amplifiers power multiple speakers, usually at lower power ratings. 2-Channel and 4-Channel amplifiers can power car speakers or low powered subwoofers. Occasionally you might see a 5 or 6-channel amplifier that can power speakers and subwoofers at the same time. The most common setup is a monoblock amp to run subwoofers and a 4-channel amp to run door speakers. Check out our Knowledge Base for more information.
Maximum Power Input
This is the maximum amount of power (measured in watts) that the unit is designed to handle. Exceeding this amount can void warranties and damage the unit.
55 watts

how would I get my remote turn on for the amp?
john v on Aug 3, 2014
Best Answer: Couple ways to do that: 1. Just run the remote wire directly to your radio; 2. Splice into the cigarette lighter; 3. Take your remote wire and wrap it around a fuse that is an "accessory turn on" and plug it back into the fuse box; 4. Soniceletronix sells some of the PAC Line out Converter that have the remote wire built in, so when the speaker turns on, it turns the amp on. Only draw back is they sometimes get stuck on and can drain batter. I used the fuse box option because mine is in the trunk so less work.

Installed a Sony XAV-601BT using the C2R-AUDI harness into my 2008 Audi A4 that had the Symphony head unit. I now have very low output from the factory rear speakers/subwoofer. From what I gather the Symphony head unit puts out 10v for the RCA outs and the Sony only 3-4v. What is the max Vout on this unit? Thanks
Steve B on Sep 8, 2014
Best Answer: Hello Steve,

The XAV-601BT provides a 5v output. Obviously this is still less than the 10v you suggested [which we cannot confirm, but assume to be accurate]. Traditional LOCs, like the PAC LP5-2, will give you a nominal ~4v .
It sounds like you seek a Line Driver. The Rockford Fosgate RF-BLD, for example, will take the signal, via RCAs, that you provide it and will boost the Vrms up to 11Vrms.
