2 18's or 4 15's?

[stephens30228 10+ year member]

I have an explorer with the third row laid down, I am wondering if it would be better to push 2 1500 watt 18's or 4 600watt 15" subs. I am on a budget of $1000 used or subs and amp so go gentle please. I'm on stock electrical too so 1500 is pretty much my limit with a 130amp alternator and stock battery. I also have to build the box so probably more like $900 shipped for it all. But I have the opportunity to get the 18's with a box for $550, they are DC Level 4's, the 15's are OA's, for $515, but I will have to build the box. Thanks. Sorry about the same topic type, I couldn't find out how to delete my old post.

really depends on your air space stephan .if you can fit the 18's in at least 12 ^3 box i'd go 18's ,4 15's will need at least 14 ^3 ,they may get louder but wont get deeper and may not push as much air

Well that answers one of my questions, thanks, but what about the excursion of those dc's? I mean I don't know what size the box is, and even then I can build one still if I don't like it, but if I am only pushing them with 1500 of that 3500.1 will they push enough air for me to realize? I am still learning.

I don't know about that the 4-15's is a lot of come area compared to the 18's and I can say the oa15's will be just fine in 3 cubes per

I have the the little brother to this, the BXI 1205D and it does rated without a sweat, runs cool at 1 ohm mounted under the seat. Hardly any voltage loss and nothing but a big 3 in 2 ga and a Yellowtop up front ...

these are good amps for the $ and they do rated as well.

if the box for the LVL4's is spot on for what you need, then go for it...the OA's are good too, but you have to get in line for them and the web site says it is a 70 day wait.

The OAs are from a guy in my area, well about 2 hours away lol but I wasn't sure how the BRZ would like my electrical, someone is selling one for $250 near me.

Id go with the 18's. I havent heard many setups in my day but i have heard 2 18'' lvl 4's one time at a comp and they sounded amazing.

I'd go 4 15's if you have the space for'em

Man you guys are making this tough lol.

Not that hard of a choice. Figured out your available airspace then figure out what subs/combo will work the best.

 

[stephens30228 10+ year member]

Well I am assuming that airspace isn't the only factor here. Or else I assume that you would have 4 15's instead of your 2 18's? Just sayin.

The BRZ is 2 steps lower in the HiFonics line than the Brutus Elites I posted earlier. The BRZ has been clamped to do just a hair under rated, and the Elite (BRE) is underrated...good amps and very efficient at 1ohm. The BRZ's are silver and the BRE's are black.

It a major factor.

My setup is temp. I had 4 18's b4 in a different vehicle, newer vehicle I put just 2 18's in. My new setup will be 4 15's walled, most likely a 4th order.

Just do what I said if you don't have any subs just yet.

Well if you go to sell your 18's let me know, maybe i will come pick them up from ya. Anyways, it will be about a month before I get my money, just narrowing down my choices.

I am selling them. 2 Are going to someone for a trade offer and the 2 that are currently in my ride are for sale. I'm currently deployed right now and have about 1 month left. PM me if you are still interested.
