i have few units Blaupunkt 4 channel amplifier BQA-160 , item is new , never open . asking RM120 for 1 unit , good for component and 6X9 speaker , not suitable for sub .
I have heard alot of comment on the usefulness (or "uselessness") of the device on a N/A car. But i personally felt some improvement on acceleration when fitted one on my car.
i do have something to share buy would like to make a collection of comments and review. Technical explaination and experience are mostly welcomed
What you guys think? ;)
