General Audio

I have a Sirius satellite radio, that the plug/transformer end of the powercord for it, no longer works. I want to wire it directly into the car. However, the transformer steps the current down to 5.2v/1.5a. My question....based on a system that puts out 14+ volts, what size resister would I need in order to correctly stepdown the power going to the radio? My biggest concern here is frying the radio itself.

What about this one??? http://www.extech.com/instrument/products/...450/407732.html

i have a 15" xcon and there is gonna be pvc pipe ports behind the magnet how much clearance does there have to be for proper airflow, it is only getting 300rms in this enclosure.

What would be a good audio system... i had a set up in mind but i think im going to scratch what i had in mind cuz it was out of my price range i want somethin that has good SQ and is a good daily driver but when im with my friends and want to show off i can turn it up and make it hard for them to breath... also im kinda tight with money so i can work with up to $1000 going into the trink of my car im lookin for 2 15's i listen to everything but mostly rap & r&b and bass tracks... anyone has a good Sub/Amp combo for $1000 if its 1100 or 1200 thats fine too

Anyone have any eperience with these? I want a cheap DVD player/monitor for my son in my car, but I don't want something that's going to crap out in a few weeks. Sonic has what appears to be a decent one for $150.

Well guys i jus have a simple ? I have two american bass hd 15s i have a small trunk and i want to go aero port the guy i got the subs from wants to sell me two 8in ports i fogot the hz but im woundering will i b able to go with aeros or classic slot (04 grandprix) thanks guys

So my cousin just got a boat, he doesn't want big system, he wants something would just give him good sound, so my questions were that boats operate on 12v so i wouldn't need all those of marine audio or do I? Can I use like a regular car deck and speakers and amp? He just wants 4 speakers, 2 off the amp and other 2 off the Hu's power and leave the rear channel on the amp for a sub. But do you really need a sub for marine use would you be able to hear it? He just wants some thing little not go all out just for chillin...

I was wondering whether or not I needed it. Im getting a Q 15' and I wanted to know if it would rattle enough for me to need dyna-mat. I have a little truck,chevy s10 ex.-cab, so it wouldnt be too expensive to do jw if its necesary.

The JL 8W1V2's are 4-ohm, and rated at 150w according to JL's site. The 125.2 is rated at ... 125 x 2 RMS @ 4 ohm. I think a 125.2 would be sufficient for a pair, but wanted to ask before buying incase someone knows of a reason why this is not a good idea. Thanks!

ok so i have 2 dc level 4 15" with the level 5 dual 1 ohm coils and they are rated 1500 a piece and im only pushing one hifonics bxi2010d (its max is 2000 at 1 ohm) to them so i know its not nearly enough power that they can handle and i know that the amp prob isn't putting out 2000 at 1 ohm. My question is should i get another hifonics bxi2010d and run one amp to each sub or should i look into something like sundown? like their 3500d or something like that??? thanks in advance for the help??

I'm thinking of a pair of W6v2 13.5's sealed. Would a Sundown SAE-1000D be proper to power a pair of those? It's going in a 2006 Corolla Type S. Right now I have a ported Icon 15 powered by a JBL GTO 1201.1 II amp that puts out 1100 watts at 2 ohms and a Batcap 800. I want to switch my system up to a sealed setup and think the W6v2s sound awesome. So I'm going sell my amp in favor of the SAE-1000D and do the big 3 and replace the Batcap 800 with the one of the bigger Odyssey drycell batteries and a solenoid. However, I'm contemplating on what to do for my front stage. Which would be better out of these 3 choices. Choice 1: A good componant system in the front door…

I have researched and researched but I cant seem to figure it out Cadillac CTS, stock Bose system, stock amp/10 inch subwoofer that has a bump that's not bad However I would like a tiny bit more bump I'm wondering if I can just replace the stock sub with an aftermarket one Any help will be appreciated Thanks

I have a JL 450/4 that was quite a good amp, but the other day two channels burned up and now only two work. I'm not sure if I should run with this amp again or try something different and possibly better. I was thinking of putting in a single FI Q 12" in a ported box with a Sundown SAE-1000D. I've never used their amps before, but they seem to be well respected. My setup currently is as follows: HU: Alpine IVA-W200 Front: Focal Utopia 6.5" (older model) Rear: Focal 690 CA1 (6x9) I looked at the Sundown 100.4, but I'm not so sure the output will be enough. The JL put out more and the speakers handled it fine and sounded good. I'm just looking for a possible alternat…

i have an s10 and it has bags with 2 viar 380 comps and im getting a fosgate 1500x1 and wondering if i should get a 200 amp or a 160 amp alt for the truck. i belive the fosgate is like 140 and the comps pull like 30 amps. ive done the big 3 with 1/0 and got a yellow top this is the last thing to order.

I want to use the line out from an Alpine MRP F300 amp to temporarily (1-2mos.) power a mono amp for subs until I get a head w/sub pre-outs. Any suggestions for a good reasonably priced one. This is very temporary. Also, will doing this affect the 4-channel speaker outs of the amp?

New guy here. Looking for help on a potential audio setup for my 2010 Dodge Charger. I'm looking to get 2 12" subs, amp, and enclosure first. ( <<<looking to spend about $800. is that feasible?) Then looking to get an aftermarket head unit down the line. I honestly have no idea about car audio so I need some suggestions. I want something that sounds good but hits hard. I mostly listen to hip/hop n rap so I like bass but not to the point that's all I hear. Any suggestions or opinions would be great. I know you guys probably get these questions all the time (sorry) but I figured I'd ask people who know something about car audio.

Hey guys im in the process of taking out my system in my truck. Well i took out the three batteries and all my amps and subs i have in my cab and when i went to start the car it wouldnt turn on. My volt meter was reading like 8. something volts and to turn it on i have to have it jumped. Any suggestions on what it could be. My fuses by the battery under the hood looked fine. The alt is fine as well it idles at like 13.7 volts. thanks.

I need the specs on this Amp or someone to help me know proper way to install!!!! Thanks

Okay guys I need some help. I wanna order some speaker box carpet for my box but I have no idea how much I need... My box is 30"wide, 24"deep, 13"high. How many yards will I need? What kind of adhesive should I use?

I need 4 yards of the silver comfort suede that select product sells. SP actually calls it gray but looks silver to me. Part # CSUEDEGREY Now that SP is dealer only, I'm kind of screwed. I can't find what I need anywhere else so my headliner remains unfinished! Thanks!

I looked at both company's products and was a little baffled as to why AA would want all of their subs to have a 1.85 ohm(3.7 since all of their subs are dvc) whereas FI's products are 2 ohm/vc respectfully unless FI's are the same but just secretly rounded. I used the calculator on http://www.the12volt.com but couldn't get the AA's to come out to an even ohm no matter how many woofers are added to the mix.

My friend just bought an SA 15 with a SAZ 1500D v2(used) I told him that amp is too much for that sub but he said nah he knows what he's doing. Now he's calling me and asking me how can he power the sub without blowing it. Lol. I don't know what to tell him as I've never overpowered a sub and wanted good results before lol. Any tips on how to do so? Thanks in advance.
