It really depends on which particular woofer you are talking about. 6.5s can have some really thick bass if installed properly. A pair of Exodus Audio Anarchy 6.5" woofers in a proper enclosure will pump out some serious bass. Its not often you have a 6.5 with 14mm of one way linear excursion, AND its XBL^2 so it'll be distortion free right up to Xmax. Another high output 6.5 is the Elemental Designs 7kv.2 subwoofer or their e3.6 sub.

You've got options for bass in a small space, just a matter of picking a project and some goals and getting to it.

 

Once again thanks for the idea's !
Trying to keep it on the cheaps too... I know you get what you pay for...but
Wondering a couple things which might sway me

So if I do a compact box I will be able to hook it into my boat which has a punch 60ix and four polk db65's which would clean it up which is a plus. This option gives me versatility.

My F150 setup is the punch 150a2 with Pioneer premier d720's. If i was to hook a sub to this amp/speakers would it be ok? What about the higher frequencies making it to the sub, can I block it?

 

Good idea on the compact subwoofer! The only thing I would be careful with is theft, if it's not bolted down or well hidden, it can be easily stolen. I'm sure you can get a nicely designed box to fit one 8" woofer inder the seat, hopefully you have some room there.

As for the amp blocking higher frequencies, your amplifier should have a switch that allows for low pass, or only low frequencies to pass through to the speaker.

 

Thanks Phatta. The amp is already hooked to a set of pioneer d720's and is running I think in "full". So neither the HP or LP filter is being used currently because of my full range speakers. Now if I hook the sub up to the same amp I don't want the full range for the sub I will want the LP on but that will mess up the sound on my speakers.

I realize most people will say just get another amp, yes that is probably a simple solution.

Is there anyway to run the sub and my speakers off the same 2 channel amp and have my speakers perform "full range" and have the sub perform the "low range"?

 

Yes there is a way! Its called Passive 3 way corssover. This is a cheap alternative, and for sound quality, isnt the best choice compared to crossing over actively.

+2 on the crossover. That would realistically be the only way to run your doors and subwoofer from a 2 channel amp while still maintaining a proper filtration of frequencies into the sub and full ranges. Personally, I would run your doors off the headunit and run the subwoofer off the amplifier mainly because the amplifier does not put out a chunk of power greater than your headunit. I would run your headunit to the amplifier via subwoofer RCAs, properly tune the EQ on the headunit to your likings, and tune the amp to LP with proper gain setting. To me, this will be your best way of achieving an even level of bass, mids, and highs. Again, this is what I would do if I were in your shoes. Other people might do it differently.

 

hey i'm looking for the same thing, i was thinking about a sub under the passenger back seat since i don't have a jack under that seat. what would be best?

 

Ok, now I am looking at 8 inch subs...thanks a lot guys.

 

Thats what i was thinking if itwould fit. an 8 under the back passenger side seat since i don't have a jack there (person who had the truck before me decided it wasnt needed)
