Here's my alpine 9857. Very nice and the display is sweet.

someone please help me out...i just bought a system but completely forgot that i had to buy a wire harness. and now that i'm looking for one, i cant find it. i got a 2005 Pontiac Grand Am, 3.4L 4 Dr Sedan

Although I'm not worried about buying an amp with enough power (bc I buy quality gear) I'm still unsure how efficient an amp really is. My really old PPI PC 2150 A/B class says in the manual something like 70% efficient which is better than many class d amps now (I read something about the JL 500/1 being about 50% effiencent.) Anyone really know how efficient their amp is or how I can find out without buying one? PS I have a 06 Toyota Highbrid and I'm thinking that the normal 12v system is going to get taxed pretty hard with a moderate system in there. My system will be pair of 6.5's up front (likely XR's or Mpyre's) powered by my PPI PC2150 Single SS RLP 12 in a port…

ok well i dont know if this is exactly where im supposed to put this topic, so correct me if i'm wrong. I'm looking to start making some stuff for my dorm room next year, and i was wondering, what some good brands of amplifiers that are out today in the home audio spectrum. i mean power amplifiers, for subs and such, and also some other good 4-8 channel amplifiers for speakers. I assume i can just use a home theater receiver for the speakers and such, but as for the power amplifiers, im lost thus far. What are some brands that you all like, that y'all recommend. ive been looking at some Crown, but i dont know. My dad has meridian, but thats out of my price range for s…

Has anyone else had the whining noise from the RCAs with the 880? I was switching around some wiring today, accidently touched a speaker wire to the ground wire on the amp and all of a sudden I hear a whining when I turn the vehicle back on. When I grounded a single RCA on the front pre-out the sound nearly went away, still there just barely audible So a couple quick questions about this.... When grounding the RCA would I have to do it to every pre-out being used? (white and red of all 3 pre-outs if all were being used?) Is there a nicer looking way of doing this? Should the deck just be sent to pioneer to be fixed instead?

Any opinions/experience with Eclipse's XA series amplifiers??? http://www.eclipse-web.com/amp/xa1000.html

Pioneer Premier P880 PRS, easily the highest end deck i've ever bought. 24bit dac's, l/r seperate eq's, 5v outputs, a ton of xvoer points. here are some pics.... http://www.sonicelectronix.com/pictures.php?id=6822

Gonna be using this for my sub amp, probably on a new eclipse sw8000 10" until my Diyma 12" comes in.

Which amps (beside JL's Slash series) have auto turn-on feature???

HOW MANY RMS DOES 2 T20001 bd??

What's this? OOO, just peeking This is going to be unused Business end Diddle Note my roommate's ugly feet. Gross. Thanks JoeHemi... great doing business with ya

http://www.jvc.ca/en/consumer/product-deta...model=KW-AVX706 Buddy of mine gave me a price of $775CDN. What do you guys think? Going to have to do a little modifying to my dash to fit the 2din in the 1.5din opening, no biggy. Dremel, fibreglass, and elbow grease are my friend

HI! My name is Bosco Ruiz, Iam from Nicaragua and I bought 2 TEAM RF 12" 2000 RMS Each sub.... I have a questions. Can I put 1 T20001 For each sub.?? I can not to put 2 T30001, Cause it is too expensive....I have only 1 T20001 but i could to buy another one for those subs. What do u suggest??

i was looking around at profile's site and looking thru their refurbished amps. are these amps worth buying? not looking at buying one right now, but i had thought about getting a few two chaneel amps, bridging both, and hooking them up to my sub. thought about getting a third and powering my front speakers. that would be like $100 ish for 3 amps....can't beat that. Are there any other manufacturer's website's that sell refurbs?? anyone had any experience with them?

ok i just got a new 9855 with 4 volt preouts and a used merlin m41 from flakko, and i go the 9855 to work, but when i hook up the amplifier, nothing, not even the power or protect light came on, but then today outta nowhere when i turn on the car, i hear this semi loud click noise, and the amp turned on and i could listen to music, but wasn't very loud, even at 20 volume. it then proceeded to shut off again, and now has no music coming from the speakers, and the amp's lights (power/protect) are off as well. i had this same problem with the last amp i had, before. and im sure when i put that one in it will have the same problem. anyone have any ideas? and i have speaker…

Do they stll make those small, cheap amplifiers??? You know: like the Sherwood 25 x 4 (max wattage) type deal (for use with a factory radio).

What type of sealant should I use on my rubber gasket (firewall) that is "temporary" (can be taken off in a couple of years)?

Doesn anyone have any expeience with these amps? I am currently shopping around for new amps for the possibly near future and was reading a little bit about treo. I know their subs are of good quality but what about their amps?

ok i just got a alpine cda9855, and the preouts say 4 volts. i am going to be using a us amps ax1000de and a us amps merlin md41, and the input gain on the ax1000de is 150mV to 3 volts. and the md41 i dont have the manual on. so my question is. will a 4 volt preout work with this amp, and if anybody knows if it will work with the merlin as well. also what exactly will the difference be between 2 volt preouts and 4 volt preouts. becuase im pretty sure 4 volt is better. thanks

anyone know the deal on the new Punch amps, other than boring heat sink and more power?

whass up guys! I am new to this forum.So pretty much i'll get right down to the point.To me Us amps,are always a good investment.So,how do these amps compare to US amps;Digital Designs,Zapco,American Bass,and autotek amps?I'll be using one of these amps to push 3 12's or 2 15's.Thanx for any help you can offer.

Whew... Got my new head unit installed as well as the steering control module, thanks to the help of Electrodynamic. Looks good but the installation of the steering control module (PAC SWI-ALP) was a little more involved than I anticipated. Still very happy will post pics soon!! PS- Sounds really good.

I bought a usa-425 from Ryan, the amp looks great and everything, but when hooked up...... nothing. Im thinking its the preouts on my headunit. What is the best way to test this theory out? Besides hooking the amp up to another headunit? Also, if it is the preouts anyone know how these are fixed, if at all? Thanks

Alpine, Eclipse, Clarion, or Panasonic... ...in the $150-$250 range.

I'm having a small problem with my system. I can really use some feedback from you guys. I have 2 soundstream eg-15's(400 rms ea.) hooked up to my SS tarantula tr880/2 (880 rms). everything is great ,they hit hard, but when I turn up the gain and volume for higher spl the amp will shut off. but only on certain hard hitting songs. I'm pretty sure the amp can handle these volumes, being an old school tarantula. I'm thinking it may be the voltage drop it causes at these volumes. But the voltage drop doesn't seem to bad going by the headlights. I do only have a stock alt., and I haven't done the big 3. I'm wondering if voltage drop would cause the amp protection to turn off.…
