PAC TRUNK-LOC

I've used several of these in the past few years and they always worked great. No turn-on/turn-off pop with the remote trigger output. I have even used these run off the outputs from factory mid/sub amps with no problems. This unit does have a 'rolloff at 20 Hz for subsonic' but I couldn't find any info online or at the manf. website. IME it's probably only -6dB. I will definitely try the newer PAC SNI-45T on future installs.

If you want to keep the factory head unit this is a must o and dont forget RCA's

I attempted to install some extra speakers in my truck along with an amplifier to give these new speakers a boost. For some reason the radio head would work for about 10 minutes and then shut down. Even though the amp was made for "speaker input". This product fixed that problem and actually made my system sound better! It was much easier to install that I thought, taking only about 30 mins. I'm slow at this kind of stuff though.

This product is fantastic. It does exactly what it says. It's best feature is the ability to isolate alternator and other static producing noises on the high voltage side from the RCA output. the result is completely static free sound coming out the amplifier. I also bought a spare for future use in other vehicles.

I would definitely recommend this product. I hooked it up on a 2004 grand am SE1 with a monsoon system 2 wires and I was done basically worked like a charm.
