So tonite I set my gain and ssf according to the thread on here. Only questions are, when getting rms for 2 zcon's, do I add both together, or just what amp says. Amp is a saz2500d. 1 ohm says 2500 rms. square root is 50. Set amp output to 50 vac. Then took 50*.707=35.35. Turned ssf up till voltage dropped to 35vac. Questions are, is that correct? Or do I then readjust gain back up to 50?

Just curious what all of you guys are running as far as engine belts with your HO alt? I'm running a new stock GM one now, thinking of getting a gates belt...

Just want to wire a friends two under-dash neon's and one under the back seat to a single toggle switch mounted on the dash. Battery ---> power wire (16ga) ---> inline fuse (5amp) ---> more power wire ---> 12v power on switch Acc on on switch ---> neon x3 (splicing all together to run off the single switch) Ground switch and tube. Right? Wrong? Your feet smell? Perhaps just using the cigarette lighter in the car. Cut the wires off the back of the lighter in the dash, cut the DC adapter off of the neon, wires from lighter into switch ... ? Probably the easiest way if it works ... Thoughts and opinions. Going for simplicity. - Steve

I have a 2005 4runner Limited with the JBL package. I am about to install my headunit and have already gotten my wiring harness and dash kit, but need to know if there is anything else specific I will need. Seen a few modules that are said to be needed to bypass items in the 4Runner. Not really sure what it meant or if needed. Anyone who has done an install on a 4th Gen 4runner (03-09) please help. Thank you.

I tried to look up past forums on this and had no luck. How much will a zx2500 draw at 2 ohms? Im gonna run 4 for a daily setup and im trying to figure out how many alts and what amperage alts i should run to properly supply these amps with enough amperage. thanks

anyone try any of the newer ppi phantom amps? im looking @ the 900.4 and seems like its inexpensive under 200 shipped for 145 x4 and active capable . wondering if they do rated and are clean sounding amps ... i know the oldschool ppi were great would like to try the newer stuff if its still decent quality . any info is appreciated

Alright dont have much cash but what are some of the best headunits out there that are around $200. Please tell me why it would be a good choice.

Will a aq750 be able to run at .5 ohms?

I plan on running my sq 3500 @ 17 volts...has anybody had any problems with the amp at Tht voltage

So I have a delima. I have a Chevy Sonic and the stock alternator is only 100 amps. I cannot find an upgrade for it nor can I find anyone that can rebuild it to have higher output. My question is, what can I do to upgrade it? I have already done the big 3 and upgraded the stock battery. Any suggestions would be appreciated.

i do not know if this is the right section for this, i was wondering if you would see any voltage increase in creating a heatshield or putting sound deadening around it to keep it a few degrees cooler

I've narrowed my choice down to these choices. Mechman 270 DC Power 270 XP I was wondering if the extra 35-40 amps at idle is worth the extra $150. I'm only running one AQ2200D, and I don't have an endless pile of money. I'm almost certain what the responses will be, so I think I'm leaning towards the Mechman. Let me know!

I have an aftermarket Pioneer HU (AVIC F900BT) and it has a sub control level (from 0 to 6) and bass boost (0 to 6). Would having a bass knob make any difference or is it the same thing as the bass boost on the HU?

ok, im going to be running a 15" FI BTL Ported at 33hz By a Hifonics Bxi-2608D(rated 2600W RMS) going into a 2000 Hyundai Sonata. Right now, im planning on upgrading the Big 3 Do i fuse that Batt to the Alternator or not? Doing the upgrade with 1/0 And running a 1/0 power wire fused at 300A to the amp, and Grounding it with 1/0... What is the MOST Logical and Cost Effective Mothod to Kepp it all in good standings...? Knowing that any of these methods could be inefficient for what im running, here we go... Capacitor? Second Batt? Higher Amp Alternator? Turn the Gain Down On the Amp? or anything else? please tell me what you think will be best and why the other suck balls …

Does anybody have any idea where Sundown Audio amps are made ?? t Thanks.

The Big Oki and his Zapco 9.0's Still laugh at it since it is soooo true.

I have 2 sets of re xxx 6.5 components ... i was thinking about going active but i do not know what the benefits would be and if it would be worth me spending the extra money for another amp ... would these speakers do well with an active setup? they are rated at 150 rms each (mid+twwet combined) ... how much power should i put to each mid and each tweeter? the ohm rating on the set is 2 ohm but will that change each speakers impedence?

so when i put my latest head unit into my car, i left a cd in my old unit, and i have been trying to get it out. i have a power supply that i plan to hook up to it, but i can't figure out where to hook my wires up to, so i need a diagram to find out where to hook my positive and negative leads....any one know where i can get a diagram? the unit is a Clarion ProAudio DRX6375. i googled and eBay'd and all i found was a picture of the diagram but the seller on eBay made it microscopic because he only wanted buyers looking at it.

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

I cant stand this chit anymore! OOppss can I swear in here? LOL Anyways Ive done everykind of search for the PPI car amps on all models. High and low through Google searches with rephrasing the words and the whole bit! For makin some bomb ass amps they suck with tellin you how to use the Dang Things!!! Well yeah I know they sold out and ya da ya da but CHHEEZZZ can I get a lil help people! Startin to get frustrated,mad,tired and ready 4 a new amp! Only had these PPI's for a lil over 4 months together but now I think I want a 1500W to 2000W Mono Amp or 2 channel. But I put in some time and efforts pickin up these PC 2150's and they are tight as hell. But I have this one …

Which sounds like a better idea to you. I am in need of a new double din gps radio and i also plan on going active. Here are the choices I can either get the new kenwood dnx9140 sax 100.4 for mids sax 100.4 for highs (will be mostly tuned down since the tweeters will not be able to take 160+ watts of power as they are 2 ohm) i would need to use the crossovers on the amp or the new kenwood dnx7140 rockford fosgate 3sixty.2 (used as the crossover) sax 100.4 for mids sax 50.4 for highs both cost the same or if you feel that there is something better that i should get please let me know

Ok I'm not that good at this but have a newer amp with 6 chips on the PS sink. Seems to be two transformers and 3 fets each, the output is on other side of chassis. Well the 3rd and 6th one are shorted pos to neg and blew the +12v trace. If shorted then they must be bad, the rest are near same ohms and not on/shorted at rest and all same # chips. Anyway, can I just replace them....what would cause this to happen? Would something else be shot too? They are $15 each so far I've found. Yes this is a junk explode amp, but might as well see what I can do its like new otherwise and 500wx1rms so not bad. I've been told not to substitute parts on new amps, have no idea what was d…

This seems like such a simple question, but I can't find the answer. What are the advantages and disadvantages between two different amps that put out the same out of power but at different resistances? Mainly looking for answers on a more technical level, like which will put less strain on my electrical system or which is thermally/mechanically better for the subwoofer. I have a Fi SSD 10, D2 and copper coil, and I'm looking for a 1000w amp to power it.

Anyone know how or who to talk to?
