i gotta guy wanting me to a build for him in his 73' caprice convertible and i need some suggestions! he wants to go big but he doesn't like ported boxes for some odd reason. now he's seen my other builds and he expects it to be as loud as those. i might be able to convince him to go ported but it really has to slam. here's the catch, it all has to be in the trunk! but the good news is he has an open wallet. im thinkin 8-12" sa's and about 12000 watts rms. any suggestions out there?

I dont know how it will sound with a convertible but I would think you will lose a lot of sound. Why would he want the system to slam hella hard but not want ported enclosures? That sounds like a lot of shit to go in a trunk also. I think you can pound with a lot less. 2k-5k watts and a couple of 18's would slump pretty good in the right circumstances. But if you love to build and he loves to spend...get out the grinder and start stuffin.

There ya go.

You will loose ALOT of sound and possibly tear the top itself. You need to talk to him and find out his goals, and why he doesn't like ported enclosures. I see NO logical reason why he would want 8 12"s and WANT to be sealed. Beyond the fact that he could say " I got 8 12"s in my truck and it's rattles like King Kong and Godzilla back there thumpin." Which would sound like absolute trash.

I have a stern passion for hating trunk rattle.

i agree i hate trunk rattle, but this is what he wants. he wants the trunk to rattle. i think i am just gonna have to convince him to go ported and do 8- 12" in 12cu.ft. @ about 34 hz giving them right around 16000 watts. hey he wants to spend the money and im not gonna tell him no. thanks guys

I saw someone with 2 boxes in his trunk, so he could play with only one box, or with the 2 boxes when he wants to be louder.

The boxes were both the same dimensions, with the same number of subs.

Maybe you can try that?

It's a lot of 12's for a convertible!!! Those will kill his car quickly !!!!!!!!!!!!

just my 2cts!

I worked in the industry in Florida many years ago and many people seemed to feel that trunk rattle was the primary objective!!!

They'd install 6 subs (keeping stock mids and highs....some of the real coniseurs would buy tweeters as well) They'd come to pick it up, turn it up all the way stand outside and watch the trunk rattle and be very happy if the trunk had a nice buzzing qualtiy. OF course these guys would get 100 yards down the street pull over, crank the gains on their amps all the way (because of course that's a volume knob) then come back later that day needing new amps.

Keep in mind moving enough air to do a hair-trick would definitely destroy a soft top. I'd do a dozen Bass-Shakers attatched to his seats to give the feeling of low freq and just a couple subs.

How about you start with some space limitations and budget?

12kw is a bit much for someone who is not an experienced SPL competitor to use on 8 of the SA-12s

If you go sealed you only need 8 cubes for 8 of the SA-12s... 12 cubes is enough room to port them.

well the guy had 2 of the soundstream 4000 amps on 4-15's in his avalache and i metered it on the termlab and he was hittin 152.1, so he knows what loud is and i already told him that he wasn't gonna get the same performance because of the the car being a converible, but i was gonna try to get him as loud i as i can. i can make his trunk rattle thats easy but i want to get it loud in the cab as well, and i don't care about the roof tearing. he's already aware of what may happen, now it my job to get them to happen. also how are those sa's musicly? can they get loud and still sound good?

That sounds like your problem..."can they sound good?" You want loud and quality? Maybe that's why he wants sealed? It's usually the most accurate and blends better with mid-bass when installed properly but so can a port or band pass that's designed right. I don't know if I'd try to be too technical with your customer. He sounds like a lot of talk without knowledge to back it up. Build him something nice and see what happens? Make it flashy and "bump". You're gonna be frustrated if you're trying to do an SPL rig with that vehicle tho.

Convertibles = Not sound quality or SPL friendly

well its not going to be a spl or sq car at all, i just want it loud and sound good. and your right he he thinks he knows everything and don't know shit, but i gotta make him happy. he's a friend of the families and he's a repeat customer that isn't affraid to go big! my next project will be to re-do his avalanche now thats gonna be fun! stay tuned for that one!
