Opinions on which to use?

I have a 96/Bose and am replacing it with a headunit that has 2v pre-outs.

From what I've gathered in threads on this forum, the 2v pre-outs (as opposed to 4v+) are going to result in low volume levels.

The only solution i've seen is to use one of these two units to increase the gain.

For those who have used either one (or both) what is your opinion? Any problems with either one?

Thanks.

 

They are the same thing.

 

Get the Scosche. The Metra 70-7221 [correction*** 70-7551] harness with RCA connectors is what you need to stay away from due to the low pre-output voltage on your headunit.

 

70-7551.

 

Thanks for the correction Nismos14.
