Amplifiers / Head Units / Processors / Electrical

So I just had a Viper r350 put into my vehicle...I want to add additional sirens. I've seen some 120db ones online for as little as $6... Anyone know if there's a limit to how many I can run off this alarm? I'm thinking 1 in each corner of the vehicle would be nice...

I was wondering if I should get an outside crossover and eq or combination of them for my truck, I am using the active crossover on my H/U clarion dxz-785usb, it has Digital time alignment on it and 18 db slope 3 way crossover in the deck. I am running my front channel to my tweets @ 3500 hz then running my dual 5.25 in the door of the rear channel ran @ 90hz and up then sub channel @ 90hz and below Would I improve my SQ buy adding and eq/crossover to the mix or is the head unit alone good enough. It sounds good now, just wish I had a little more control over the freq.

MTX re-Q, Fosgate's 3.sixty, JL's Cleansweep...there's a metric crap-ton of these Factory stereo processing units out there. Anybody got any experience with any of them? Are they even worth it?

...a 4 channel amp w/ all 4 channels being used? http://www.kenwoodusa.com/Car_Entertainment/In-Dash_CD_n_DVD_Receivers/1-DIN_CD_Receiver/KDC-MP342U

So when trying to calculate your voltage, do you use ur ideal ohm load or the actual ohm load measured with a dmm? also say your amp does 1500 watts @ 1ohm, will it still be putting out that much or close to after impedance rises (say to 1.4ohm)?

now i know how to mod the MTX 81000D, but i was wondering if anyone knew, to mod the 1000D to run @ 1 ohm, is it the same as to mod the 81000D?

Ok I just got an audio pipe 1300 amp it's a 2 channel amp. If I wire it two the outside + and - and hook it up to a 4 ohm single coil sub will that show as a 2 ohm load bridged and give it 600 watts or read it as 1 ohm and 300 watts??

Like the title suggests, would it be practical to build a tube amplifier from scratch for a subwoofer? i need between 20-40w power @ 25hz 20w is acceptable but the more the better. Looks and size don't matter. Budget is $150

I need to find the right amplifier for the job and there are a few selections I'm not familiar with. I am planning on useing 2 Diamond audio D1 10' 200rms in a sealed downfiring box to go under the seat of an '02 GMC Sierra extended cab. My choices so far are RE XT 800.2----not to familiar with these amps Diamond Audio D400.1----these either, but I have heard them on the same set up in the same truck sounded great,(also most expensive of the amps) Hifonics BXi1201----had this one before, it was awesome, but it was for SPL, I want to lean a little more towards, SQ this time. Any other suggestions would be helpful, I am trying to stay around $300, and I need at least 400 …

Right now I'm powering my 12" Treo SX with a RD 1750.1 wired to .5 ohms. Not sure exactly how many watts I'm getting taking effieciency, ohm rise and other things into consideration but overall I'm happy with its output. Was just curious though...given everything is the same other than switching out the RD with a Sundown 2500 wired to .5 ohms (sub is dual 1 so I'm looking at .5 or 2 ohm options) how much of a difference could I be looking at? The pre sale for the sundowns looks like an amazing price and honestly I'm considering picking one up.

at the moment i have a hifonics brutus bxi-1210D. I recently saw on the ssa store front page the saz-1000D and also heard the sundown amps are rated at 12v which is awesome for me because I still have not upgraded my electrical, i will be just havent yet. My question is, will it be worth it to sell my amp for another that does around the same power? Isnt the sundown just a better all around amp? I just think its a little flashy and funny lookin haha.. Good amp dont get me wrong but I want an amp with 0gauge inputs kinda. I am running one fully loaded bl 15" and i think the saz would just be a better match.. does anyone know if the saz1000D has a bass knob? you know like t…

when i hook up my sub to the terminal i take the 2 wires from the black and twist them together and put them in the black terminal right? then the same for red?

lets say i get this amp: http://shop.vendio.com/inetdistributors/it...7115/index.html and run 2 coaxes off 2 channels for 60-70w @ 4 ohms each and run 2 subs off the other two channels for 150w @ 2 ohms each run rca's from the rear channel jacks in the amp to the sub control jacks in the HU, will i be able to control the subs from the HU?

How many in-line fuse holders do I need? 1/0 from front to a Stinger T splitter (http://www.woofersetc.com/p8033/SPD512--Stinger-1-0-Gauge-Tee-Distribution-Block.htm) and 1/0 going to SAZ-1500, and 4ga going to a Alpine PDX 4.150. I am going to order a Stinger 150 to go between the SAZ amp and the T and a 60amp to go between the Alpine amp and the T Do I also need a 250 amp inline up front under hood or is that overkill? Thanks

Currently my setup is as follows: Acura RSX HU: Alpine IVA-W200 Front: Focal Utopia 6.5" and tweets Rear: Focal Polyglass 6.5" Highs Amp: JL 450/4 Subs: 2 Fi Q12" Sub Amp: RF T20001BD I've never tried hooking up 3 sets of components in a vehicle before as I normally have enough with two sets. I was thinking of putting some kick panels in and using the Focal K2 5.25" components I have sitting in my closet. Is there any way I could hook this up without another amp? If not possible, think I would be ok just removing my rear fill and using that channel on the amp for the K2's? Or would that be like too much just coming from the front and only bass in the back...I don't kn…

does anyone have an idea why my amp stays on when my pioneer avh 3200 hu is off..it just started doing this ive only had it for a few months..

My friend has an 07 GTI and is thinking of running an AQ 2200D to two Fi Q's. My question is, will this amp be happy powered by the stock alt (120 amp). He doesn't really want to run an extra battery unless absolutely necessary. All suggestions and advice is appreciated.

Ok so i got a 3sixty.1 It was free and brandnew versus the cost of a 3sixty.2 I know theres a big difference but i figure free can negate those differences for you. Anyway. My radio has some alternator whine/engine noise. Its an AVIC-F90BT. I was wondering if the 3sixty would negate the engine noise because its grounded or would it just simply amplify it. Thanks guys.

Is it ok to mount the amps on the sub enclosure?

I have a 220A H/o alt for a 01 lincoln LS and I am current running just a stock battery. If I get two other batteries, even though Ive not got my amp yet, and install the alt in my car would there be any damage? Or if I hooked it up now to a stock battery would there be any damage? and second question, I flubbed up and read the ebay post wrong and ordered 2 S3400 from XS power, I wanted D3400s, whats the difference and would I regret using the S over the D series?

With a pretty significant build on the horizon now steering towards higher end equipment, i still am not ready to part with my factory head unit unless it becomes an absolute must. I prefer the OE look and like the fact that my navi and bluetooth are integrated in the setup now, although i know that with a little tweaking i could likely make them work with something different, if needs be. On the G35 w/ the Bose system, all the processing is done at the actual factory amp. The leads running from the factory receiver are low level already and many people prefer the results with the RCA cables spliced/soldered into those leads over using an LOC. I myself initially had used…

Hi guys. As the topic states. below is what I have considdered so far pls give advice .. feel free to add and give a reason. preffer not to get processor just yet. system will be used for 2-way active. eclipse 7200 MK II (this is what i wanted to get but now people say its not all that) Price around s$1050 alpine 9887 around $800 singapore dollar clarion D2 (price not sure and the ugliest of the bunch) Pioneer DEX-P90RS (looks promising but way over budget and no-one here have it, so that i can audit it. s$1500)

Might be old news, but I just caught this today. http://12volt.com/12voltonline2/index.php?...Itemid=88888907 Looks pretty awesome, pretty smart amp. http://www.focal-power.com/products/dual_monitor.htm
