Amplifiers / Head Units / Processors / Electrical

So earlyer this summer my kicker 650.4 got a little hot and burnt up. I was a Electrical Engineering student for 2 years so I know a little about the specific components in an amp. I took it apart and saw that it was a piece I haven't worked with before and about 10 of the same one fried. This is a picture from ROE(the amp guts section). I had my friend take close ups that I'll try to post tomorrow but he is having problems with his camera so not sure. Hopefully one of you guys can tell me what these are and if i'd be able to replace them. They are the first 4 black pieces under the metal on top and bottom and maybe 3 on the next sets of 3. Thanks, Austin

The amp in question is a Linear Power 4.1HVS taken from another forum.. in the highlighted section above, i know there is a flaw in the maths.. can anyone please point it out for me??

Ive heard good things about their amps, and I love the volt meter on the air models. Are the specs accurate on these, and are they good quality? They are dirt cheap, 134$ for the t700 with shipping to AK added on amazon. I was thinking of getting the t700 to put on the Dcons if it would be better then the soundstream rubicon 2.600 that I currently have. Couldn't find any actual reviews on them though. Thought I'd ask for your opinions, lot of smart people here. Thanks guys.

Anyone know?

i want blue tooth/ipod/changeable backround pic, the ipod is most important and SQ. what i have is in sig. i have good stuff and want the best deck for SQ. they both have the options i want. i think the p980 has a better screen and i think the ipod on the x991 is better. no one around me has this on display so I'm buying blind. please help me

Its been awhile since I posted. But I'm back in the stereo business now. And the shop here sold someone a Power Acoustic "CAPCELL" 800-amp. 2 months ago. She came in today and her woofers basically sounded like they were crying. She thought they were blown. I crawled in and looked and the Capcell was displaying 8.24v and when it would hit would drop as low as 6.96v some time. Basically I don't have any experience with capacitors because I dislike them. But this is a hybrid so I wonder how can I recharge it. Just hook it on a battery charger for a few hours? The system is a SPL GRLA5500.1 on CVX154ohm x 2 http://www.poweracoustik.com/pa2006/product_AUDIO_addon_CAP…

Long story short, I'm keeping the factory Nav/HDD/BLUETOOTH/IOD/DVD/MP3 head unit in my '11 Ram. I installed a PAC OEM-1 (OEM-CHR3) for the plug and play ease plus remote turn on from the can bus system. My question is on setting the output levels of the OEM-1. I installed the OEM-1 and just turned all four outputs on the LOC all the way up. Is this correct? Is there any reason I wouldn't want them all the way up to feed the amplifiers the highest signal level?

Ok I have a dual brand double din trying to hookup to the pac rp5 gm31 to retain chimes steering wheel controls etc on my 08 silverado....the harness off the pac unit for SWc has the option for a 3.5mm jack and a blue wire yellow stripe..the 3.5 mm jack won't work because the dual double din doesn't have a plug for it....the dual stereo has a swg(ground) and sw1 and sw2....what needs hooked up I can't find answers anywhere on this any help would be appreciated

hey... i was wondering... if you paint an amp, will it hinder the cooling process of the heatsink? i wanna paint a Profile CA400 black to match the dual EU box.

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 got this HU recently from soneone. The Radio creates music through my RCA's but when I try and play a cd it read the cd and says its playign the cd but viola no signal......And if there is signal its not audable........can someone help here??? J

What are ya'lls opinion on Panasonic head units??? I can get this model for free from work through reward points.

How do you turn off the demonstration mode???

i know this sounds like a newbie question but i wanted to get the right answer. okay, so i have a rf t1000-1bd. it says that the amp is wired in parallel inside the amp. does this mean i can put a wire from each terminal on my woofer to each one of the 4 outputs and it will automatically take my dual 2 down to a 1 ohm load internally?. basically i wanna bump up the wire size going to my woofer because im used to the jumper and twist technique, but if i can get a fatter 10 gauge wire i'd like to do that. so basically instead of me doing the parallel wiring and only 2 wires coming from my sub, i'll have 2 wires from each voice coil, 4 wires going to my amp and the amp will …

OK I have made the decision to go with a custom dual alt set up in the Taurus...yada yada ya mount it, longer, belt, etc.. done. BUT I got to thinking about a few things I learned in school and I was wondering if anybody else on here with a dual alt set up has run a equalization connection between the two to prevent the alt that has the stronger field excitation from taking all the load and turning the other weaker one into a motor? And how do you know that both are in phase as not to double voltage when they are 180 degrees out of phase, 28 volts will fry my car. anybody with knowledge of electron physics that could help would be GREATLY appreciated

I have an alpine cda-9855 and i has the option to use a 7 band graphic or a 5 band parametric.. what is the difference between the graphic and parametric??

What kind of Parametric EQ do you guy's recommend? I have a clarion deck, it only has 2 volt pre-outs but its loaded with options such as you can rip someones cd directly on the deck, SD card mp3s, Ipod etc etc. Anyway it only has Bass and Treble for EQ therefore I want to either get a Parametric EQ or maybe one of those high speed 30 band eq's with the clipping light on each band, What kind do you guys recommend? money is a concern and its gotta be black Also where should the eq on my deck be set at when i get one 0 for bass and treble or -6 for bass and treble? I would also like it to be a min of 7 bands

I finally installed my Eclise CD-8445 and I'm loving it. However, I don't quite understand how the parametric equalizer works. It's a 7 band eq, I can change the gain of each frequency range...I get that much. How do I know what frequency to set each "section" of the eq to? Each section has three frequencies to choose from and I don't know what to select. On a side note...anyone know how to fade the sound to the front? Can't seem to find a way with the Advanced/Pro mode on. Thanks in advance

While looking around at H/U's Saw this on Chrutchfield. Looks pretty interesting. Opinions? http://www.crutchfield.com/p_333ASTRDSM/Parrot-ASTEROID-Smart.html

just thought id share this they have 35 ah batteries for a decent price sealed lead acid agm batts http://www.parts-express.com/brand/power-sonic/509?utm_source=Retail&utm_medium=Email_Newsletter&utm_content=PowerSonic&utm_campaign=email111512

Which is better Passive or Active? After askin on other threads i figured out the difference, but not sure which one is best. All i can figure is Passive would be better because you can use one channel of amplification and get 2 or 3 way crossover, and have that one channel power 2 or 3 speakers. So = better use of power. For Active you need one channel for one speaker. so more power is required by needing more channels, but that give you more control, right? Will one sound better than the other?

hi, a freind has given me his set of alpine type r componots but one has a blown midbass driver. now i am wondering is there anyway that i can find out what the highpass and lowpass is set at? they are the newer ones that have an 110 rms rating

Ordered my amp! It's an old school Soundstream Tarantula monoblock. Specs are as follows: Continuously Variable Low-Pass Crossover Three Stage Level Input Indicators Output Clipping Indicators Phase Inversion Switch (0 - 180ﾺ) Selectable Differentially Balanced Line Inputs Fully Balanced PS-2 Input Line Output Gold-Plated 1/ ? Power Connectors Discrete Balanced Class A Drive Boards maximize linearity on low impedance loads Drive Delay 2? eliminates "turn-on" and "turn-off" pops and noises Chassisink? Semiconductors are situated between the circuit board and heat sink for optimal thermal transfer Power Grid? design optimizes current delivery to and from the power supply T…

Looking around for a new head unit I've found that the majority of units from reputable companies (save alpine) dont have pause in their mid level units. Kenwood, Pioneer, Eclipse...none of them have pause in the $2-$300 range. My CD3434 doesnt have pause. Even sony units lack pause. Pioneer and Kenwood's lower units have pause and all of their highest units have pause...but in between it seems to be the companies think we dont like to pause our music or compeat... /rant

will i saw a car with a pc in it over the weekend and i want to do it but don't know it it is going to work better the a head unit so if have done this or if you know if i can do a sq build with it
