How many dB SPL?

[username taken]

How many dB are your subs pushing, and what is your setup?

Reason I ask is I am looking to build a subwoofer setup to augment the stock system, and I am trying to determine what setup will deliver the results I am looking for.

Loud and low is my priority, clean is secondary but still fairly important.

I am considering some of the following:

Anyone have experience with the above? Let me know good or bad.

if you want SPL nothing you have linked is going to do that. You need air to make your subs loud. what cab do you have first. where do you want to mount your subs. my old truck was in the 140s with 2 18" juggernauts. if you wan a bad ass deal on some amps let me know im selling my amps out of this truck.

Remove your back seat and build a sealed wall box with no less than 6 15" subs. Throw enough power at them and seal all the leaks you can in the cab and stand back. If you tune your box right, you will be in the high 140's easily.

Okay I should have been more specific. NBS Crew Cab. Looking at under rear seat options with available airspace.

Need to keep the cab/ bed functional. No cutting or boxing into the bed, all seats intact. What can I fit under seats/ behind seats that will hit? 15's, 18's are wayyyyy overkill for what I want to do. This is a daily driver, tow pig for the 5th wheel, hauls the family and work supplies

I just need to know basics - like will a single audiobahn 2000W 10 hit harder and louder than the JL box I linked? Is that my loudest underseat option? What direction should the sub fire? Floor firing? How far away from the nearest surface for decent loading? Is there enough airspace for a ported box, or is sealed my best bet b/c of the limited space? Are the amps I linked worth a damn? They seem inexpensive for the wattage they produce.

TIA for the help and feedback

Take a look at this thread. Wes (whitetrash21) built his own box (for a Crew Cab) with a single, down-firing Audiobahn 2000w sub. This may give you some ideas.
