Did a thorough job of sound deadening my car, which was long, but well worth it.
Replaced the stock 80A alt with a 170A HO alt from Ace Alternators. Stock battery out, Kinetik HC1800 in. Added a Kinetik HC600 as a secondary battery in the rear hatch. Upgraded stock power/ground wires to 1/0 Kicker HyperFlex, and 4 gauge Kolussus Cable.
Recently jumped on the PG RSd bandwagon lol and have to say I'm quite pleased with them. Tested different placement options before finally deciding to use the factory door locations for the mids, and having the tweets up in the dash. For the mids I simply made some custom MDF brackets. To install the tweeters I had to remove the dash, then used a drill and hole saw to get them flush mounted. Crossovers installed and mounted inside the passenger glove compartment.
