as the title says crescendo audio ccx65 vs Rockford Fosgate Power T1652-S thanks

Kinda in a jam here guys. My Clarion HU has took a shit on me. I cant turn my volume up to test before it blinks, cuts off, and shuts everything down. After it resets it come right back on and it plays fine at a moderate to a quite loud level, but it's cutting off on me before I can get it to full volume. I need some opinions on a new one. What I want is a Pioneer 880PRS, but I don't have time to wait around on a used one to show up. I need one now even if that means finding one that does what I need and keeping my eyes peeled for something better. The options I need are unfortunately becoming obsolete and giving way to DVD, navigation, blue ticks and all that shit. I do…

Hello everyone! I have a question regarding my Eclipse. I have a CD5030 and also have a XM Onyx that I'd like to run thru the decks AUX. Does anyone know if I'd be able to use the same AUX plug with the CD5030 as the CD5425?

I have a strange problem with my hu...the remote and touch screen stop working but all the buttons on the hu itself is still working properly. what can be the problem?

Are there really any half decent HU's these days? Originally I was gonna go with a Kenwood eXcelon KVT-696. But I don't need a DVD player. I would have had this system done by now but I lost my job back in Jan and just found one. The rest of my system is: Subs: 2 IA Death Penalty 12" Dual 1 Ohm Amp: Sundown SAZ-3500D Speakers: Im still not sure. But leaning towards Polk speakers Speaker Amp: Kicker ZX350.2 Sub box: Probably something between 4.5-5.0 cuft net @ 33Hz My alt and battery will also be upgraded too. This will be going into a 06 Dakota Extended Cab.

Vehicle: 2003 Chevy Tahoe 5.3L Stock alt size is 130 I believe. What size alt would you guys recommend to successfully push my Fi BTL N2 with the AQ2200D? Is a HO alt even necessary for the system?

hey guys im putting a new system in my car and i pretty much have everything i need except for wires, amp kits and a box. my focus right now is to get wires that are the best suited for my system right now. Im not sure what type of wires or amp kits i should so any help would be awesome. I have a 2002 toyota camry Kenwood excelon headunit Image Dynamics 6.5" 2 ohm Component System (CXS62 V.2) (front door speakers) (1) 12" Alpine Type-R sub (SWR-1243D) sundown audio SAZ-1000D (1-channel mono amp) (for sub) sundown audio SAX-125.2 (2-channel amp) (for the front speakers) i think knukonceptz.com has some pretty good wires but i just dont know what type i should get, what ki…

ok so i bought some 0 gauge welding wire for my amp. can i just ground my batt. to the chassis and engine then ground my amp to the chassis? this probably sounds stupid but i dont wanna fuck up

what would be a good o-scope for a reasonable price, only want to use it for tuning amps, thanks

what is the advisable length of cable from battery to fuseholder for big three thank you

I drive a 08 mazda 6i sedan, non bose. I have a LOC with 2 pairs of rcas (front/rear). Right now I have a 2-channel amp for the front 2 speakers on the front rcas, and a monoblock for my sub on the back. Well I purchased a 4 channel amp, and 2 bass shakers (one for under eachseat up front). What I was planning on doing, is switching my 2 channel amp for the 4 channel, so all 4 speakers would be on the 4 channel amp, and the 2 channel with the bass shakers. The monoblock will be untouched, if it doesnt need to be. Do I need to just use rca splitters, or could I just run the 4 channel off the front RCA, and use the rca output of the monoblock to feed the 2 channel? Im afr…

ok i know there is a topic here somewhere on this but i have searched using keywords and didnt find what i was lookin for. i would like to know what are suggestions to correctly power a sundown 3500. it is not s competition vehicle jus a daily driver. the speakers will be 4 fi ssd's ( i already own them) run @1ohm. most likely this will go in my ford escape which already has 0ga upgrade, kinetic 2400, batcap800 for electrical. i know i need an alt so i will get probably one runnin at 14-15v 300-400a. i might only compete once or twice but this is just for me to blurr my vision when i'm feelin it. how many batts should i add after i get the alt?

Hi all, I will be using the Alpine Imprint Module with my Alpine iDA-x305S. My Question is, will I have to use the disc and mic tuning kit (KTX-H100) for tuning or when I plug the unit in; will it unlock all the tuning features of the imprint and I can tune it manually? because that's what I would prefer.. thanks.

I have an older 4 channel class AB amplifier that was made by Dragster Audio Art. Amplifier goes straight into protect. I asked Chris at dB-r a couple years ago and he said more than likely it was bad output fets. Chris does not work on older amplifiers like this anymore. I am looking for some feedback on Ampmedics more than anything as we know what kinda quality Mr. Mantz is known for. Here is a couple board shots of the amplifer. It is actually a great amplifier and was solidly built in the EU (European Union).

Hey all.Im going to be buying a 2001 Mitsubishi Galant and im needing to get a HO alt.Ive been searching the internet for over an hour now and all I found was a 180amp alt,but im wanting a bit more output than that.So I was wondering if someone could tell me where I could get a 200+ amp HO alt for the car.The engine is a 2.4L 4 cylinder.Thanks

When i turn on my amp, it makes a very high pitch sound, so what could it be or any suggestions Amp is a rf t1500-1bd, subs are 10 chaos, hu- jvc Ask what ever questions u need Thanks

Im thinking about getting a clarion eq., and I was Wondering if its worth the trouble? I've saw a lot of installs and I don't see to many running them.

im looking for a head unit for my gfs explorer she is wanting a dvd havnt decided if its gonna be double din or flip out single din i have found the alpine ktp445 which it was told was like a mini amp that i could use for my components maybe and was wondering if i could just match the the wires by colors from that to whatever headunit i wanted weather it be pioneer kenwood etc etc. and i was wanting to get some of ur guys input on different headunits and as to why u like them. the only thing we are looking for is if it plays dvds and an ipod can hook up too. price range isnt a big deal right now but wanted it under 800 if we can and be able to change songs on the screen …

I was driving around pushing the system in my tahoe no harder than i usually do and it shut off. i get home and check fusing and all externals are good but 2 of the internal 40a fuses blew.. one has a huge black spot on it and left a bunch of nasty residue on the amp.. I plan to go out and just buy some more 40a fuses tomorrow but im wondering how in the hell it happened? connections in this vehicle are solid, or i would have blown ANL fuses. Does this happen when pushing a system pretty hard? Its just never happened and it has me concerned why it happened and COULD i have damaged my amp? Had this system up and running with absolutely no problems for about a year now. any…

Is hifonics a good way to go for amps?

I was talking to guy at the local shop and he got me thinking about pre-amp voltage and line drivers. I have a Pioneer 3200DVD with 4v pre amp outputs. He told me that a line driver would boost that voltage and make a night and day difference to my system. If someone could tell me how they work, and what it would benefit to me if I got one. Head Unit is stated above and the amp is a saz-2500d. He exclaimed it was needed, I don't think it is. He may of been trying to make a sale. Thanks in Advance!
