Possible Subwoofer Set-up - Opinions Welcome

[01 Suburban LS]

Well I'm thinking of adding some subs to my 2001 Suburban. I pretty much decided on four 12 inch subs and obviously an amp. What do you guys think of this set-up and how do you think it will sound. I've put systems in several cars, and they sounded great. But filling a small car with bass is quite a bit different that filling a Suburban will bass. The two 12's I had in my Lexus IS300 sounded awesome in the IS300, but it sounds like crap in the Suburban.

Just my .02....I would steer clear of the Xplod stuff. It just isn't that good.

 

Two twelves in a bandpass should rock your Burb pretty good. 4 would be overkill, but that might be what you want. I have two 10s in my Blazer in a bandpass, and they are pretty dang loud. Fosgate amp and subs in the Blazer are about 7 years old, and are awesome.

 

I have Fosgate amps and Stillwater (Kicker) subs in my 02, and they are waaaay loud...But so are the mids and highs, so it all works out between the ears.

 

Now, I don't build my systems in order to scare old ladies at 3 in the morning, or win SPL contests....I build them to sound right. No matter the music that I play.

 

If you just want LOUD BASS....Go with the Kicker Solo L7s....They will take a buttload of power, and cost is above average, but they go big.

 

Like I said, just my .02

well I guess it depends on your type of music and funds but I also would stay clear of the xplod stuff
