Affiliate disclosure

As an Amazon Associate, CarAudioCalc earns from qualifying purchases. Product links on this site are affiliate links. If you follow one and buy something, we receive a small commission from Amazon at no extra cost to you.

What that does not change

It does not change the price you pay. It does not change which products get recommended: every product here was selected by reading its published specifications against what the page claims, and a long list of products that matched a search and were the wrong item is recorded in the site repository with the reason each was rejected.

It also does not change the arithmetic. The calculators and reference tables on this site are computed from published relations and would produce the same numbers if nobody ever bought anything.

Prices

Prices shown come from the Amazon catalog at the time the page was built and change often. Treat every figure here as a guide and check the listing for the current price. Some products return no price at all, usually because the listing restricts price display, and those cards say so rather than showing a number we made up.

Other relationships

We do not accept payment for placement or for a specific rating. If that ever changes it will be stated on the page in question, not buried here.
