tmitchell162630 Posted October 3, 2022 Report Share Posted October 3, 2022 So I've been planning up a build for a 98 Monte Carlo. I want it to be two 12 inch subs and the port facing forward through the folded down rear seats. The main thing I've been trying to figure out is how powerful I can get before the roof flexing starts to become a concern with damaging the windshield or back glass, or separating from the glass. So if anyone has a similar setup and can share their experience that would be great. I was thinking about doing 2 base power PSI platform 5 subs on a crossfire 8k amp, but I want to know if I can step up to the high power 4500 watt subs on the Star Power 10,000 (11k rms) without any big concerns. I'm going to put 120 mil sound deadener all over the roof and the rest of the car to strengthen it (the car doesn't have a sunroof). But I don't want to put in a roof brace, I want my car to look very stock inside. Link to comment Share on other sites More sharing options...
jmanjr82 Posted October 3, 2022 Report Share Posted October 3, 2022 Huge factor is going to be what kind of freq your going to play often? I ran 2 12in Audioque HD12s at the time now it's soundqubed. On a pair of RD5750s I believe RD audio is no more, in a Chrysler Sebring 2 door coupe with no issues for 14months. It looked like the windshield was breathing, but never had the seal leak or anything and I didn't deaden the roof just used spectrum spay on the trunk.

Mostly going to be normal rap songs, occasionally some bass boosted music in the low to mid 30s. Thinking of getting the box tuned to 32-34 in that range.

jmanjr82 Posted October 3, 2022 Report Share Posted October 3, 2022 Honestly it's going to be more trial an error. Some people glue wood to the roof to help might be am option since you don't want the pole support. Link to comment Share on other sites More sharing options...
tmitchell162630 Posted October 3, 2022 Author Report Share Posted October 3, 2022 Guess I'll just get the bigger amp and turn it down if it flexes too much. Definitely don't want to be missing out on any power Link to comment Share on other sites More sharing options...
jmanjr82 Posted October 3, 2022 Report Share Posted October 3, 2022 I ran 11k and had mo issues. If your windshield moves to much you will know pretty much immediately. Take some Vids when you get it going. Link to comment Share on other sites More sharing options...
