Truck Subs

[GFezz]

Just finishing up the install in my '86 Silverado, cd player, and a Concept cc-754 behind the seat. Got 2 3.5's in dash,
2 4.5's at bottom of dash, 2 6x9's in the cab corners, and the problem is the 10" sub on the hump. Needing to get it outa the way, and it's not sounding too good anyway, it's in a 13 x 16 x 6 box w/ 2 2.25" ports. What's the good setup for sub's?

[camel]

i don't quite getwhat your saying, u mean the back of the cab about 15 inches up? did u build or buy your box? what sub do u have. i would toss the 6x9's cause there isn't alot of space behind the seat, and put some 6.5"'s in the bottom of the doors. and a sub or 2 behind the seat.

If you want subs always put them behind the seat. Also get a sealed box sealed hits harder than open. 10's and 12's always work good. Find a box about as long as the seat and as tall if you dont need the room. If you need room get two separate smaller boxes but still have enough air for your speakers or the sound will distort. And dont buy a cheape amp because they will always mess up and dont buy cheap speakers because they will always somehow blow.

don't buy cheap boxes either, like the ones at future shop or circuit city. just build one out of 3/4" mdf, or go to home depot and they will cut the panels for u. then u just need to screw and seal them together. don't use plywood, it sucks for boxes, and make sure it is anchored to the cab. and don't cheap out on the amp. expect to pay 1$ a watt. don't use 12's behind the seat, they won't have enough room to breath or u will hurt the subs. i have free plans for a custom box to fit behind the seat and it is perfect in everyway, its loud and tight.

[ChevyGuy]

I have 12's and they thump and they dont distort either but the box is huge but still gives enough room to move the seat all the way back. And i have my amp under the seat and out the way... If yall want i will give you the demensions of my box when i take it out in a few days. Its as big as a stock seat and holds 2 12's.

I also have (2) 500 watt 12's behind the seat. They are in seperate sealed boxes and sound great. But they do rub on the back of the seat because I have the seat back all the way. I would recommend seperate boxes with speaker guards to prevent the rubbing. If you do build one big box, I recommend that you have two seperate chambers inside (1 for each speaker). If the box is open inside (speakers share the air) they usually dont sound very good. I would also put the amps under the seat. I have one amp 500w 4 channel (bridged to the 2 12's) under passenger seat, and one 300w 4 channel under the driver. The reason I did this is because on some songs I want to change the sound level on the 6X9's and tweets, I can reach under my seat and turn the knob. Also be sure to screw the amps down to prevent them from sliding and being stolen. I would also have a through bolt in the box behind the seat going towards the bed. this will also slow a thief down. 6 x 9s in the door sound good and some tweets under the shoulder seat belt is a good location (sounds good and most people dont see them). Also when you wire the amps under the seat NEVER run the RCA cable near a power of remote wire (this creates a humming or motor sound, very common mistake). Since i run 2 amps I have 2 toggle switches on my dash under the sterio. I use these switches to control the remote wires to the amps. this allow me to run only one amp if I would like. this is good for determining how some speakers are working or for adjusting sound options on amp. hope this helps

hey chevy guy i want to see the demisions for your box. with 2 12's i wouldn;'t have thought u that u could get the internal volume that 12" subs need, but if u guys say u can do it then i guess it does work. but 2 10's in a truck that size would always be louded, the volume of the cab is to small for 12s. the speakers will move, but the sound just won't be asload, the cabin gain won't be as great.

[ChevyGuy]

Im outa town for the moment but i will give you the deminsions when i get back. I have 2 12's Orion's and a 655 Boss amp and a Pioneer DEH 1000 but with a different stereo they still hit hard.

[PHOENIX]

I used to have 2 Fosgate 10's behind my seat. They did sound loud but the hard hitting bass wasn't there. When I installed the 12's I had much more bass, overall the system sounded much better with the 12's.

[camel]

how much leg room do u guys have with this set up? i am 6'2" so i have it al the way back and the subs still fit. whats the amount of internal box volume?

[ChevyGuy]

heres my box deminsions....top is 15.5in by 57in... the bottom is 57in by 8 in.... top is 57in by 5in....the side is 5in by 15.5in by 8in by 15.25in.

[PHOENIX]

Camel, my friend sits in my truck and hes probly about 6'-2" he never complains about leg space. But I do think its probly a little to small for someone of your height. Im about 5'-9" and its just right for me. I dont have the seat all the way back because of the 12's but its pretty close. I would have to say its probly about 1 or 2 notches away from all the way back. I also have a Grant steering wheel which makes sitting closer more comfortable.

[camel]

yea my seat is all the way back, or at the second last notch, i am not too sure. decent set of 10 sure do sound good. i don't think i would ever put 12's in my truck unless i made a hole right through to the bed. then had all the room for the big box that it would need. the subs mmats pro 12's, with an mmats amp? or maybe a phoenix gold xs 2500. prolly have to stick with the d series amp tho. the infinitys under the dash will stay, but the cheaper pioneers in the doors might be goin soon for a set of infinitys, then i need another amp. well too many dreams, not enough cash for the system, we need a potent 350 first. then drop it, and rims, and alternator, and i need to win the lotto.

[GFezz]

I'm seeing a lot of good ideas and also a pattern here, my 10"
Pioneer sub on the trans hump has got to go! And yes, built the box myself using some formulas d/l'd from some seemingly knowledgable sites. Two subs behind the seats sounds like the way to go, I'll have to opt for the 10's I think, I like the seat all the way back..Yup, and my amp was exactly discounted to $1 a watt. I don't pay msrp for anything..
But now, I kinda like my 6x9's and the amp behind the seat,
but in veiw of all of your veiws, I'll be rearranging, subs getting priority...thanks fellas

[camel]

i have my amp behind my seat, and i just have the box off set to the drivers side. make sure u have both subs mounted next to eachother and then a brace on the opposite site. this way it hits the hardest and feels liek u have a bigger sub, the sound waves go throught the seat easier too. i have some plans if u like?
