The reQ-5 by MTX makes adding amps to your factory radio easy. I have a 09 F-150 and an aftermarket radio and installation kit would be
out of my price range. The reQ-5 solved that problem at a fraction of the cost. Now I have super clear sound , tremendous bass and my dash is still factory. Well worth it.

It allowed me to integrate aftermarket amps to my new car! No more plain factory sound!

Works very well but has a couple of problems and the manual could use some attention. Installed in '07 Tundra driving Sony 4-channel and a sub amp. I'm not using the supplied aux input (yet).

One major issue is the 15-second off time on the auto-sensing trigger (to turn amps on/off). This is too short and will cause amps to turn off between songs when one song ends or starts quietly. Once level increases enough, ampt turn on but you miss part of the song. I ended up using accessory B+ and bypassing sensing circuit. This timer should be closer to a minute or two.

The supplied fuse holder is subject to poor connection (e.g. hitting road bumps) causing pops and amp shutdown - replace it with a better one.

Each channel has two inputs to the unit (8 total + a sub). With a "normal" factory HU, half of these are unused and clutter up the installation. I bridged the sub input as the manual suggested and clipped the unused wires at the connector.

There are two surface-mount red LEDs near the power-on LEDs. There is no explanation in the manual but they appear to be clipping indicators.

The "front/rear sub level" switches are poorly documented. I can't really tell what they do. Are they high-pass x-overs? Controlled by the sub x-over frequency? What frequency is the -3dB, -6dB at? Is it volume sensitive?

There's no info on MTX's web site and MTX has not responded to an email query about these issues. Since this is a new product, hopefully we'll see answers soon.
