Looking for recommendations for an amp and subwoofer. I own a 2022 LT, and while the stock speakers do a fine job, I really want to feel the bass. Are there any guides out there for doing the install myself, and for anyone that has done it, how would you rate the difficulty as opposed to having it professionally installed? Also, for anyone that has installed an amp/sub, would you recommend new speakers as well? If so, which ones? As a reference, I mostly listen to technical death metal, so I want to be able to hear the nuances without the sound being muddied by the double bass drums common to this style of music. Thanks.
