hi guys i'm brand new to the site and looking for some insight. i have a 01 ZR2 with 2 coustic 12" in a sealed box powered by a DEI300 amp. nothing crazy but it's been losing it's quality and volume. i dont want to spend a pile of money to update. i have a couple different boxes that i could use one that holds 2 12" and one that holds one (both sealed). i am looking to get the most bang for my buck basically. lets say i have a budget of about $400cdn. should i go with 2 lower quality subs or one higher? keeping in mind my amp is about 300watts. i had this setup in my 88camaro when it was brand new and hit 142db. i know putting it in the truck i'm losing alot of sound but it's quite alot and hard to beleive. i tried useing a different amp of about the same quality and nothing improved. so time to update the subs i'm thinking. anyway any input would be apreshiated.
