Sundown audio sa-8 v2

[lose_money]

I recently bought one sa-8 v2 2ohm and had a custom box built to spec. I also bought a sae-600d amp from sundown and went ahead and installed everything. My one issue is i don't think is performing to what it's supposed to from watching videos and hearing reviews. It doesnt get to loud and doesn't push THAT much air as I've seen. I have a kenwood excelon deck and used a 4 gauge wiring kit although my speaker wire is only 14 gauge. Set all my gains accordingly and have my low pass, high pass filet, subsonic filter set. All my eq is at 0. I have subwoofer level set at max now and when I sent gain because on my kenwood deck turning the sub level up is how i get the max 4v of preamp out put. Gain is set a lil beofre half. The sub just doesn't seem to live up to its expectation. Any idea what could be the problem?

where do you have the box facing? where the box is located and facing makes a huge difference in output. Whats the measurement dimensions of the box and port length of the box?

With the gains setting, are you just guessing? or are you actually setting it via DMM method?

Most of those videos are putting 1-1.5k watts per sub you my friend have 600 unless u wired it to 1ohm

you are losing almost all sound pressure because it has nothing to load off of. Happed to a buddy of mine, had crazy subs but he just threw it on the back seat and thought WTF where's all the output? Barely getting any type of respectable bass. threw it in my trunk on the same amp and bam! Car flexing everywhere. Thats why I said loading makes a huge fking difference and yours is completely faced wrong. you might need to have sub facing towards you and port loading onto the side or build a downfire box because upfire is horrible in trucks unless its reallly close to the roof blocking out almost of the back seat to prevent cancellation.

try getting 4-6 bricks, put two-three on each side(dont block the port) and have the box fire down and see if it makes a difference.

A lil confused about the bricks. My sub is mounted on top of box also with the port being on top. I'll upload a pic a lil later

okay man, subs make bass waves and bass waves need something to bounce/reflect off of. Having the port fire up like that makes you lose a lot of pressure, doesnt matter if its in the right box, you'll not get any bass out of it if you run into cancellation.

What I suggested would be turning the box down with the sub and port facing downwards towards the floor and have something/anything to lift it a several inches off the floor so the bass will reflect(load) off the floor.

Thanks man for the info, what i did was lay the sub down and face the port and sub towards the back of my drivers seat now. I also got my 10 gauge wire in the mail. When I swapped out the speaker wire I realized the old wire was 16 gauge. It made a big difference after swapping out the wire. Repositioning the sub and changing the wire made a differnce for sure

usually the back seat's cloth is not the best place to face it either but its better then nothing lol. Cloth absorbs some bass, if you can get it under your seat, that'll be cool.

Haha thanks for the help man it sounds miles better now. Pushing way more air I don't know if it's from repositioning it or the wire change but it's better. I would try and put it under the seat or something but the box is way too big I don't got any other opinions besides on the seat. The only other place I could is on ground between back seat and front seat

yeah man, just play around with all the positioning you can, its the easiest technique to get loud for free lol. Try left side, right side, downfire etc..
