http://cgi.ebay.com/SONY-ELECTRONIC-CROSSO...1QQcmdZViewItem Anyone know where I can find more specs on it?

ok my brother is doing an spl build (one sound stream xxx-15 quad 1.2ohm coils) and we have a bugit of $600-$800 for amps and we want around 7k-8k in wattage and we were thinking 4 of these http://www.amazon.com/Hifonics-Hfi2000d-Amplifier-Designed-Dissipation/dp/B003PSAQXA/ref=pd_sim_sbs_e_1 or 2 of these http://infiniteelectronix.com/soundstreamdtr13400dd-tower3400wattrms5ohmclassdmonosubwooferamplifier.aspx or this http://www.amazon.com/Lanzar-OPTI8000D-Optidrive-Competition-Amplifier/dp/B0037YZLMS/ref=sr_1_1?ie=UTF8&qid=1311341969&sr=8-1 what do yall think for price and rms watts which one

its wierd. when my aunt found out that i was into car stereo, she told me her brother bought out and now owns USamps. how are they?? what is the reputation of usamps? from the looks of it they look mighty fine! http://www.digitalcaraudio.com/id59.htm

Quick Question, I'm looking for a new front stage amp since the 3522 isn't really cutting it anymore. I'm searching ebay for used 2 channel amps and I came onto this "Cadence Ultra Drive Z1200" as well as many others. Before i start considering the Cadence I tried to look it up for RMS wattage and other specifications. Upon research, I've found different information from different reliable resources. However, i found nothing specifically on "Cadence Ultra Drive Z1200". I found stuff on a Cadence Z1200 being a mono bock, and stuff on a Cadence Z1200c being a 2 channel. I don't suppose anyone out there has any useful information for me on the Cadence Ultra Drive Z1200? Th…

alpine's site doesn't say anything nor does the manual, but do you think the MRP-M850 would operate at anything below 2 ohm? i have a dual 4ohm 10" RL-i and i have decided i want a little more bass, so i'm wanting to get another RL-i. thing is my options are 4ohm or 1ohm if i do so. at 4ohm i'm not going to get more wattage than i'm running now at 2 because i'm only running it at about 500ish. i'd really like to not have to buy another amp though along with another sub. so you think it could handle 1ohm even though it says nothing about 1ohm? ratings RMS Power (at 14.4V THD+N, 20Hz-200Hz) Per channel into 4 ohms: 500W x 1 (0.08% THD) Per channel into 2 ohms: 800W x 1

Ok I was told the Sundown 4500D is a bad amp because the 86% eff @ 4ohms at 100Hz, so I was told to look into the HellFire 2500.1, the MTX TA92001, and the T1500-1bd. I am going to be getting 2 12" BTLs, fully loaded daily drivers. Anyone have any words of wisdom?

I have this amp and it says 600 watts @ 4 ohms.I know it has more power than this I just dont know how much. If anyone knows the specs on this amp it would be helpful. What ohms is it stable to? What should I fuse this amp at since it has no fuse on it? Does it have an unregulated power supply? Class ? It is an oldschool amp but I would like to run it, just need some info. It was made by ZED audio . I have searched the internet but found limited info. Any help would be appreciated.

I still have my 15" sundowns and I've recently been offered a pretty good deal on this amp. I was wondering if it's better than my current amp found here.

Sears has a nice battery sale going on right now. 25% off til August 23 (while supplies last).

i was wondering if the audiopipe ap30001d can run at 1 ohm stable??

I'm thinking about purchasing an Fi bl 15 or 12, and was wondering of anybody knows anything about the hifonics Brutus 1700, is it a good amp?

Just ordered an Alpine 9887, i still need to use my onstar daily. i know PAC makes an intergration for this but its like 90 bucks. dose anybody know of anoyher company that dosent rape the consumer? that price is an outrage!

How's it going guys, I'm looking into a little upgrade on my door speakers and I really need some help. Currently, I run Orion XTRs off of head unit power (herp derp). Obviously they don't get loud as they are not amplified, but I have a feeling that if amplified, they will sound like complete shit when cranked. I'd like to run something a bit more capable, but I just don't quite understand how it all works. Here's what I'm considering going with: 4 Selenium 6W4Ps 4 Crescendo SuperTweets First question: Will this be enough speakers to cover all frequencies produced in music? I've got my BTL covering the lower end, but am I missing a section of frequencies that would be lo…

I was dinkin with my stereo today. i usually run my kenwood 900/1 to my 2 12 inch kicker L5s. they hit pretty dang good. i got curious and daisy linked my alpine 350/1 ( I know its probably a bad idea to link mis matched amps like that but i was bored ) and hooked up my 2 10 inch rockford fosgates. it was VERY loud. i had it all the way up and looked at my alt gauge and it had dropped from over 14 to nearly 9 volts. just for future reference since i plan on buying a matching kenwood amp to what i have and running both, should i use a capacitor or just get a second battery? my alternator is pretty new and i have a brand spankin new 800 cca battery. my amp is wired with #2 …

i will be running 2 sa-12 d4s need help on what amp i should get both seem realy good !! i can get a refurb sundown for 320 shipped or i can get a crescendo bc2000 new for 339 i like the fact that the cresendo is new and i love the color scheme but on the other hand i think the sundown will put out a little more please help !!! i no i have been a pain lol keep changing my mind over and over and have been talking about doing a system for a while but i have one sundown already the other will be here thursday and like i said im ordering my amp tomorrow just want to make sure theres not something im missing i think i would be happy either way its going to be an upgrade…

Just finished some power testing on the Arc Audio amps that I did a review of, there posting on my site n2caraudio.com. If anyone is interested.

i havnt bought the subs so it can be either for a dual 1 or dual 2? they rms 2000 each so something around that was looking to spend about $1000 for amp would be better if its like $750 but dont think thats possible for a good new amp. thank you in advance

I'm considering the option of adding a small battery to the back to help with voltage. From searching around I seem to find one style of wiring it up. I was under the impression that I would need to a whole new run of wire from the front battery to the back. Which would result in 2 runs of power wire going front to back. This is something I don't want to do. On the other hand, like the picture below, it seems I can wire it as such: A single run of power wire from the front battery to the positive terminal of the battery in the trunk. From that positive terminal another run of wire goes to the amp. Then the rear battery and the amp are both grounded in separate locations.…

I recently installed a new amp. I had a Sundown saz 1500 on my btl n2 12", and now I run a Sundown saz 3000. The box is 2.1 ft3 net, slot ported to 32 Hz. I am a little ...worried ! I thought the change would be HUGE, but no, it is not ! I think it's louder, but I've never mesured it. Do you think I expected too much from the new amp ? My electrical seems to handle that power fine, I did not expect that !!! Only 2 batteries on a (solid) stock alt. I have a diesel engine.

Found out today that Pep Boys has 25% off online orders plus Optima has a $20 mail in rebate right now. That puts these in the $140 price range. I already have a Diehard Platinum Group 31M for the rear. Just wondering which of these 2 are best for my usage. There are mixed reviews on Google search regarding this in an audio application. I really don't plan on playing a lot with the car off, which makes it seem the Red Top would be best. Am I correct?

I was happily enjoying my new (old) amp, when it turned off. I assumed the remote wire came loose again, end of story. The terminals are screws but with no plate so it slides out easily. (Before you ask, no short, it was in line of sight the whole time). I re-connected the remote wire, and nothing. Simply will not turn back on. No blown fuse, no smell, heck, not even warm. I have no idea where to begin looking for the culprit. I'd post pictures of the damage but there is none that is visible... Any ideas on how to fix this situation? I love this amp, and would hate to retire it to paperweight status.

Would it be easyer running a 2 way active front stage by getting an active capable head unit or crossover/ processer? My amps will probley not have crossovers on them

Hi, I'm looking for your experienced recommendations, for a good efficient 3000+ RMS bass amp, it's to power 1 15'' 3000rms Fi SP4 D2 sub and keeping in mind I have a low budget(hope to spend a lot less than $600), car has already all the electrical upgrades. Thank you.

Most of this is not from first hand experince so please correct me where I am wrong. I'm just trying to save people the time they use asking this question. Memphis mc-1000d aka 16st-1000d - So the amp I would most recomend in this price would be this. VERY efficent amp at about 85-90%. Costs about $360 shipped on ebay. Puts out 1100 real rms watts at 1ohm at 13.X volts. VERY small also. I often recomend this to people with Brahma's and subs like it. A large step above JBL and Hifonics. mc is black pearl in color, st is silver/chrome. This amp gets my vote. Great SQ with low distortion also. JBL BP1200.1 - This is probably the most used amp in this range. I'm not a HUGE fa…

has anyone used these? nothing pulls up in the search.
