so i put two cvr 12' sub last week in my is250 still left the oem high and mids speakers on the door and rear but i gotta say i hate how its sounds by starters my bass dose not hit hard like i want it too the guys who put it on sed it had to do with the oem stock radio not having a amplifier to make it sound good i want ppl to hear me coiming and im not getting none of that at all any help?

 

SMH. they lied to you the OEM stereo has and amp. How many watts/what kind of amp are you using for the subs? i recommend tuning the amp to how you like it i am assuming a lot of bass. i'm no pro but when i had systems with stock radios the amp is always what made the difference IMO.

 

I'm at a loss for words right now on so many levels.

 

you need to post up what your running for anyone to help. whats the amp? how your obtaining signal? whats your enclosure? sealed or ported? is your enclosure facing the seats or towards the back? if your using a signal processor or LOC you should use the stock sub outputs instead of mid range speakers for the right signal freq. to get more low end output. you might also have your low pass and hi pass filters on your amp set wrong. need more info to help
