Looking great man!!! What are the box specs? I think I missed them.

Find a CRX. :-) You can get real loud.

I am doing a 4th order in my GF's 1998 Mustang GT convertible. The box will be where the back seat should be since the trunk is sealed off. She has 2 db Drive K9 12"s and a db Drive A7 1,500. I want to do a 4th order bandpass with a woofers behind either seat facing into the ported wide which wiill port into thr middle. = I am thinking 1 cube each sealed with 2 each in the ported side. So 2 sealed 4 ported with 80-100^2 port tuned to 48Hz. Any thoughts?

I will read through for info, but she already has the woofers. And I'm 100% sure db Specs are right. They have their slightly lower series 12" with a higher VAS but a smaller recommended enclosure.

I was thinking of just doing a normal 4th. But sealed will never be built by my hands if I can help it. lol

This is all the information I have on the woofers This is their "recommendation" for a normal box. Ported Enclosure Box Volume 1.90cu ft. Box Tuning 38Hz Port Diameter 2 x 4in Port Length 24in T/S specs K9 12D4 FS...........27.52Hz Qts...........0.45 Qms..........4.38 VAS.........37.73L XMAX........0.98in Re............6.43Ω Pe........1000/2000 QES...........0.50 SENS.......83.85dB

Dude I've never fucking seen that before, some one just linked me to it and I posted results so you need to calm your ass down. Idk what I'm looking at on there, is the reason I made a thread for some help. I've always just taken the recommended sealed, shrunk it a little and then doubled it for the ported side, as per Scott Owens advice, and it's worked great so far.

No, not all head units have a built in amplifier. The most popular that comes to mind is the CD7200MKii. Sigh I am aware some do not, but I don't think he is looking to drop $500-$600 on a non screen radio. They are called "dead-heads".

It was about the same specs we used on a 8 12" bandpass in my friend's F-150 that worked exceedingly well. This is what I came up with.

I could EASILY build a vehicle in the mid 50's maybe even 60's for less then half that. :-/ My old Ram did a 147 at 28Hz with 2k and a shitty wall......

Get to the box man! That's a great looking truck!!

What do you mean "built in amp" all radios have one.....

ok its going to be a question but what kind of electrical do you think I would need to run it at .5? thnx for the help BASS! Smashed I was looking into stetsom I love the equip so thats def.. up there! I ran one at .33 with 3 batteries on a stock alternator (almost 200 amp) with little drop below 13.

RD D9 is very very sought amp, It can do well over 6k with the right electrical.

Only real option is like two 3k's strapped.

We did a 8 12"s 4th order in a F-150 and it does 156's 157's with a little over 4,000w. And plays music amazingly.

Do 8 or 12 12"s in a 4th order.

class D amps are a definate no no for someone like myself who likes to comunicate with whales..... the further away I go from class D the more impressive the low end becomes so far I have not found any amp that even comes remotely close to my Crown A3000gti for bottom end...not even close HAHAAHAHAHA

You paid $10 for a relay and some short wire?........

What you doing to it?

If I had a need for a cheap double din I would grab one up. Seems nice. But my radio needs are all covered........

It wouldn't make a change you could notice daily.

I've been trying to tell you for years now I think that you've been going about it all wrong. Are you ready to accept my help?

sigh dare I ask how much that cost to do total? (lie to me. 20k or more would make me feel better) Won't lie. lol Like a total of.... $2,200? You can see video's of it on DD's YouTube.

It took us 4 DD 3515"s on a single DD Amp with 4 extra batteries on a stock Alternator. It was in a 2006 Standard cab Ram with a 6th order blow though. It did 152's at 29Hz and 150 at 22Hz and 150 at 33Hz. :-)
