Went Dash Diving today to install a new toy... Parametric Equalizer.. Low end brand Power Acoustic PMW-70.. Back in the late '70s a couple of buddies had these & their systems sounded great so I've always wanted to try one... I see all kinds of bulky high priced equipment that I'm sure would be better but for 25 bucks I recon the bang for the buck can't be matched.
Equalizers give you more control over the sound shape breaking the bands up more than the standard base treble control...this one controls the front & rear speakers separately as well as base volume..this only works if your running separate amps for each.
Determined that under the ashtray was the only feasible spot but the vent knobs are in the way.....
Made a bracket out of a scrap of stainless relocating the vent knobs out & back..also brought the equalizer flush with the bottom of the dash rather than hanging down...Used existing holes to mount the bracket.
