Yeah these doors on the one amp will keep up PLENTY with the two 15's. And I'm sure would hold up just fine to another two with two more amps once I put another Q4.90 on em. And thank you! I quite proud with how they came out. Especially for my first time doing doors, and my first time wrapping anything with vinyl. Just hope my door hinge pins and bushings hold up to the weight. Lol.
And yeah. Fingers are crossed on the amp. I'm a little scared to test it. lol.
