Posted October 12, 201113 yr Hi everyone I have a couple of questions regarding a build that I will be helping a friend with. He has a 96 ford f150 ext cab and wants sub(s) underneath the back seats, front firing. We're thinking something along the lines of a 8" woofer or woofers. we've measured the area and there's enough height for a 8" sub (there's about 12in of space) and depth there's about 16-18in of space. And width there's about 30in of space. He doesn't want the sub to stick out he wants it either flush with the seat or a little bit less. He wants to buy a sundown 100.2 which is most likely going to happen. (thanks ohjay) and run it bridged 4 ohms @ 400watts. Now, what sub(s) should we choose? This would be a SQ build, solely for listening and everyday. He listens to rap, hip hop, dubstep, music with good bass, and he also listens to country (he has seleniums outside of his truck lol)Budget is no more than $200 at the very most. We were thinkin 2 sundown e8s but been hearing they aren't very good sealed, which is what we want to do. Or maybe 1 sundown sa8 but then that would have to be ported, and we are not box builders lol. He wants it all sundown (we're running a sundown team at my school lol) but are there any other good 8" subs out there?Would you guys recommend instead of front firing, have the subs face up? We don't know what would sound the greatest.. Sorry haven't done much research, we're researching as I type lol. Thanks guys.

This not an "SQ" build. Your asking for trouble stating it is an "SQ" build. Your basically looking for a good all around daily setup. If wanting an all Sundown system then the E8v.2 is what you will be wanting. They can go as small as .6ft^3 per sub ported tuned to 35hz. With your listening tastes and amplifier power I think this will be a great start.
October 12, 201113 yr Author Oh sorry lol. This is NOT an SQ build. Do you not recommend sealed for these subs?
October 12, 201113 yr Oh sorry lol. This is NOT an SQ build. Do you not recommend sealed for these subs?Imo they sound fine sealed but I think you would be better off running ported. You youngins like da' bass lol.
October 12, 201113 yr Ive always found in a truck that downfiring the sub works best under the rear seat. Building a ported enclosure is as easy as building a sealed enclosure, its just the design that will throw off a novice builder.
October 12, 201113 yr What about a single sa 10 or 12, either down or up firing, with an external pvc port?
October 12, 201113 yr What about a single sa 10 or 12, either down or up firing, with an external pvc port?More than likely too deep. SD10 or 12 might also be an option though.
October 12, 201113 yr Author We don't want down firing, we want to be able to see the Subs lol. I guess the e8s ported is our plan... We aren't good at designing ported boxes, especially something like this, and tuning...... AAAAH. We've heard subs facing up and front firing in a ext cab truck and there wasn't much difference (identical setups)
October 12, 201113 yr How good is sound splinter orhan sealed?SounSplinter are (were) great built drivers. Double check the SoundSplinter section.
October 12, 201113 yr Author K. Alot researching tonight. So far two e8s is most likely since we want all sundown. Still debating on ported or sealed though lol Thanks everyone
October 12, 201113 yr Not SQ and IMO not an 8" build either. Completely bass ackwards.As always start by explaining/measuring EXACTLY how much space you have. It is just plain asinine to shop for drivers in a limited space build until you do.
October 12, 201113 yr I wouldn't use an 8". Especially sealed. It won't have enough output for your goals. The box for a 10" will be similar in net volume to what you would need for an 8" and you'll have the cone area advantage.

We've heard subs facing up and front firing in a ext cab truck and there wasn't much difference (identical setups)given the type of music your friend will be listening to i dont think he will be satified with 2 8s sealed.its very simple to build a ported box. you dont need to design the box, we can help you with that. did you already buy the amp? really you dont have the budget to get picky with brands and shit.

Cause either way would work. I just purchased a sa10 and I could sell to him, we just didnt think a 10 would fit the way we wanted to or at least sound good the way we want it to.

We wanted sealed cause we thought it would be easier compared to ported and sealed supposely has a better "tight" bass and as the guys stated at my local audio shop "cleaner bass" than ported. I believed them, sorta made sense in my head lol. We are actually hoping to buy the amp next week. Not too shabby price. He had to buy big battery and thick wires for amp wiring and big 3. He's being budget-minded.

He's being budget-minded.The guys at the store are idiots. Either way your friend doesn't care about clean or tight. For god sakes he listens to Selenium's so that is obviously the case.
October 12, 201113 yr Author Lol....... I agree with you on that though. Seleniums suck lol. He has them outside his truck though, underneath his front bumper. He uses it at TCR and when we're simply hangin out at the park or sonethin.

Get that figured out first as stated. I wouldn't go sealed if you have the room to port. I was speaking in generalities. Usually a 10" will work with a similar net volume as an 8" in a ported enclosure. Especially a low tuned one.
