[Best way to finish a sub box]

If it's built right you won't even need silicone. just glue that fucker together and let it rip!

Wood glue is not a sealant, no reason other than being lazy not to silicon or use Liquid nails.

It's one less thing you have to buy lol. If you make your cuts right and use enough glue., the box will seal its self.

ditch the 15's lol. get some SA 12's and put em in the trunk. call it good.

[4 l7 12s]

Big box, tune mid 30's, about 14-15 sq inches per cube of port area. 8 cubes net depending on power, of course. subs facing up, port facing the hatch.

I never trust anyone with stuff like this lol.

[Breaking in subwoofers?]

This is from audioque, for the hdc315 We recommend to allow at least several weeks of playing time to break in SQ Woofers, full break in may take many months. DO NOT play subwoofers at max amplifier power in the first couple of days, give the suspensions a chance to loosen up. As the suspension breaks in, the subs will play lower and louder. Also the paper that came with my sundown sa-12 said something about break in period as well.. either way they musta had dirty power to it!

HDC3's have a very stiff suspension. Movement plays a huge role in cooling. aaand i don't feel like explaining further.

[Breaking in subwoofers?]

hahaha "golden ear" would be in your best interests to stay away from that shop in the future. O-scope or DD1.

[Long time reader, first time box builder]

Good luck fitting those back there in anything more than a sealed box. Your best bet is to sell those and get a pair of decent 12s or 10s depending on your trunk space.

Bet they'd sound a hell of a lot better than those 15's.

edit: just saw your dims. from the looks of your trunk, you're gonna have to build the box inside the trunk. you won't be able to get it out of the trunk that way.

pair of 12's will sound better than the 15's you have once you build a proper box.

[What amp for 2 sa 12s under 200 bucks?]

Never played with it but i like the looks of that soundstream

Exo runs 4 of the 2500 watt model.

It does it's power at .5 ohms. I'm not sure I personally would trust an amp that has to go down to .5 to do rated power.

audiopipe and clean are not words you put in the same sentence.

audiopipe is NOT clean.

one sentence

[What amp for 2 sa 12s under 200 bucks?]

Stay clear from the audiopipe, as for the mbquart you won't see rated power though, 300-400w short, and that's clipped power (from Ray's clamp results) you'll be better off with something like the mbquart 2000.1 or hifonics brz1700.1 (same amp roughly)

I got my 1k DD1'd and from where i had it comfortably set to my listening preferences, the DD1 said i was clipping at less than half that output.

[HELP ON BUILDING A BURP BOX]

build a sealed box and find your peak. tune around there.

i'm not too experienced with burp boxes, that's just what i've heard.

[trunk rattles like a mothafu**er]

Sure hope that's not a prefab box lol.

[I need your opinion about my sound system plan]

only a pair of 12's?

you'll want to shrink that box to about 3.5-3 cubes

and no to the yellow tops. XS power is a better way to go.

[What amp for 2 sa 12s under 200 bucks?]

hifonics brutus 1700 you can get for less than 200 i think.

i wish they would've had the deal on the MB quart 1500 when i was in the market i only got the 1k for that price.

[NEED NEW SUB/BOX CONFIGURATION]

In my experience, a proper size ported box will usually do better than a small bandpass. 4th or 6th

[What is wrong with my sub?]

Do you have a DMM around? what does it read at the amp terminals?

[i have 2 btl 18s and have a question]

I'd say mid 160's start to really fuck you up.

[i have 2 btl 18s and have a question]

I sat inside yuey's (Irpirate) car multiple times, and once in his box. I'm healthier than i've ever been lol.

[i have 2 btl 18s and have a question]

Maybe I did misread, but I still doubt it will happen. If you feel like it's going to happen again, just turn it down. No sense in spending money to downsize when you have a volume knob.

[i have 2 btl 18s and have a question]

I seriously doubt you had that problem because of your 2 18" BTL's

[Cheap 300-500w home audio amp?]

In plate amps they do. Just have a little fan dedicated to one. they got hot QUICK. i got a 250 watt dayton plate amp, got pretty toasty after like 2 minutes of playtime.

[Cheap 300-500w home audio amp?]

they probably have a car battery hooked up to a trickle charger. or they bypass the amps alltogether. i've never tried messing with the gains on them before... i might try that tomorrow.

or just a bunch of 12v power supplys made for that exact application. I seriously doubt it best buy would use a battery on a charger. OP you bestbet for clean power would be a plate amp or 2

It's possible, but I have a feeling they have an amp to power the subs behind the wall, rather than the ones displayed. They allow you to switch between amps, yet output from the subs seems to remain the same. I'll have to test this theory though.

but yeah one or two plate amps depending on what your VC config is. most plate amps are 4 ohm stable, one set of leads.
