Posted March 28, 201213 yr I am currently getting ready to purchase equipment for my new setup. I have decided to utilize 3 SA8s and need to know what everyone would suggest for an amp. Not sure on whether Im going d2 or d4 yet so give suggestions based on both coils please. Edited March 28, 201213 yr by Venomized
March 28, 201213 yr The only limiting factor is your budget. There are so many amps available you can literally just pick whatever one fits your budget and power levels.
March 28, 201213 yr I can't. It depends on what power you want, what looks you want, what price you want, etc. . . I mean there are literally hundreds of options.
March 30, 201213 yr Author Ok plans changed and I think Im going back to 2 SA8 D4s with an SAX1000D and add another SAX1000D soon after
March 30, 201213 yr why what??Why are you using one less driver, and one more amp?Your asking for help, but haven't specified your goals, budget, or space restrictions either. Edited March 30, 201213 yr by stefanhinote
March 30, 201213 yr Author Well I decided 2 ought to be enough for me. My goal is to have something I can listen to on a daily basis yet still get loud with. I dont compete or anything (but would like to get back into it). The car I am using for this is a 1995 Mustang GT. I have the whole trunk (rear seat HAS to be kept and useable for the kids) Im planning the amp rack in the spare tire well and sub box will be rear or down firing and ported (still have yet to choose slot or normal port) I wont be using any rear speakers so its from floor to shelf for space.
March 30, 201213 yr I'd opt for cone area over power since it sounds like you have plenty of space, it would certainly be cheaper.
March 30, 201213 yr I find myself aggreeing with Stefan again. Cone area over power any day of the week. Actually I would go one step further and do two 12" SSA Dcons with that Sundown 1000d, especially if you can use the whole trunk.
March 30, 201213 yr Author Hmmm so 3 SA8s and a single SD SAX1000D? If theyre 400 rms then i dont think theres enough power out of that 1 amp for all of them.I have already started with the spare tire well. Cut the shape of the OEM cover out of 3/4 MDF and cut all the spare securing bracing out making room for the amp rack.Its a cell phone pic so dont mind please lol Edited March 30, 201213 yr by Venomized

March 30, 201213 yr Author Id like to stick to the 8s. I have 2 kappa perfect 12 VQ in the there now running off of a Rockford Fosgate Power 500a2 (black and grind series) and I like them but i wanna change it up a little and have heard great things about the SA8s and what they can actually do.

Can't go wrong either way.
March 30, 201213 yr Author What would you suggest for enclosure, slot or traditional round ports? Also rear firing or down firing? Edited March 30, 201213 yr by Venomized
March 30, 201213 yr What would you suggest for enclosure, slot or traditional round ports? Also rear firing or down firing?I've never played with trunks, so I'm not sure what firing orientation is best. Generally firing back seems to work well as a forum census.Slot or round, either way. Slot is cheaper, just cutting more wood, but psp aeros are simple (but somewhat costly).The flaring on the round aero ports reduces turbulence, so sometimes you can get away with less port area if your space restricted.
March 30, 201213 yr Author Ill worry about the ports once the box design is done. Right now I will get on getting the equipment to install. Thanks alot you helped immensely
March 30, 201213 yr Ill worry about the ports once the box design is done. Right now I will get on getting the equipment to install. Thanks alot you helped immenselyNo problem.Sundown recommends: "0.5-0.75 ft^3 @ 35hz" per sa8. Each driver has a displacement of 0.08 ft^3So 3x0.5 to 3x0.75 + 3x0.08 = 1.75 ft^3 to 2.5 ft^3So try to and shoot for the volume of the enclosure between 1.75 ft^3 and 2.5 ft^3 before the port displacement.*The larger enclosure will yield an increase in efficiency, but that doesn't necessarily mean the extra 0.75 ft^3 will make a huge difference either in this situation.Start a build log once you get the stuff in, and cutting away.

March 30, 201213 yr I just completed my trunk build with the same type of equipment. I did a SAX-1200d with two SA-10D4s. The box was designed by PWK. It is a slot ported enclosure tuned to 34Hz. It really shakes the pakage tray on the lows, but the bass response is real smooth throughout the entire bass range. I am very happy with the sound from my Jetta.
