Right now I have Memphis Audio 6.5" M-class components in the front...M-class coaxials in the rear with memphis m-class MCD300.4 amp. According to memphis at 12v it does 75x4 and at 14.4 volts it does 90x4. Bottom line is that the interior screams and has roughly 350watts inside the car. Right now I have a Alpine Type S 12" Sub with old alpine v12 MRV-t707 amp(had from previous setup). This amp puts out 340x1 @4 ohms at 14.4volts. So really I have more wattage inside the car which makes the mids / highs overpower the bass. Now I know I could always turn down the interiors, but thats not what I want to do. I want the interiors to match the bass from the subwoofer without having to turn down the inside speakers (I like how loud it can get if I want it to). So my question to you guys is what size amp and with what sub would u reccomend getting to put with the inside combination so that it all sounds equally loud? This is in a new civic which has a regular trunk and not a hatchback. I would like to stay with 1 12" subwoofer. Not sure how many watts would be necessary to make the sound equal. Was possibly thinking about the memphis audio M-class MCD500 which is 500watts x 1 at 2 ohms with 12 volts.
What are your thoughts?? TIA
