This is Pearl. No real mods yet just the rims from my 93 STS and XM . I plan on keeping her as simple as possible. Maybe a set of Vogues, definitely a light tint, E&G even though its like $600, a small system... You know change everything in factory location and maybe a small box, 10" max and go for sound quality as opposed to SPL. Leave the noise for the kids. I had planned on dropping a 10 in the rear deck running free air, but my research has told me not to do that. I won't get the tight bass that I want due to the trunk. A Free air system will use the trunk as an enclosure and I will end up with a BOOM... I don't need that. When I am on the NJ turnpike or 84 West I want a clean sound that will enhance my drive, and not a BOOM that will have my head pounding... Plus Wifey can't take the noise. At the same time when I get to a light and one of these kids in an Acura or Honda pull up playing this new "HipHop influenced" (yeah I said it your music isn't HipHop its HipHop influenced) music, I want to kick it in and WOW them with the sound of a grown man. Any suggestions on Sound Quality components are appreciated! I've always had boxes or tubes, I want to keep it clean and don't want a bunch of stuff in the trunk on this car. No need to front, I like the 18's. I drive... really I drive and I need meat on my rims... Plus you don't get a Cadillac for anything but the ride. Gotta keep it mean, but with a fresh swagger. theres a few folks out there that think I'm hatin on Lacs with 22' and up... Lets keep it official, I don't hate. I speak my piece and move on. Factory warranty on Cadillacs are still valid up to an 18 inch rim. If you have a brand new Lac, you throw 22's, 24's, 26's on it.... Change the suspension to fit the rims, cut the inner wheel wells so you get no scrub, have a transmission problem and the dealer tells you he won't fix it because you voided the warranty all in an effort to be the Hot Boy on the block, don't complain. Plus, you are now out of $50 - $60k based on the car and the upgrades. Don't get mad at me homeboy... I'm grown, I keep it tight and my swagger is always fresh LOL!I do have to say though, you cats with the big rims flossin it... Your rides really look good... But at what price? Hit me up!
