Looking for a parametric half din eq that has adjustable q. I've seen a couple that allow you to adjust the q for the subwoofer center freq, but I have yet to find one that will for your other freq's. Is this an option only available in a full size trunk mount type eq?

Alright so im not going to buy the crimpers for one time use... i was at homedepot and picked up plumbers solder... ik everyone says use electrical solder... whats the difference? And will the plumbers solder be good enough?... im using 1 guage to a 1300rms amp.

Hey all. The topic pretty much states it all. I've got a 225 amp EA alt and 13.6 idle voltage isn't cutting it. If anyone knows of a VCM or way to simply increase voltage I'd really appreciate it. Thanks!

I'm planning to upgrade my electrical. My battery is in the back of the car (Magnum). Couldn't I just run new wire from the alt to a pair of separate batteries? Rather than wire all three together? I'd be running a pair of 105 AH marine deep cycle batts, dry cells, separate from a regular dry cell car battery. I've never seen it done, although i'm sure it has been. Thanks.

I saw a discussion about this a long while ago on some audio site and can't find it again. I just wanted to know if there are any substancial advantages to running power wire directly from the alt to the back battery bank. For example: I have 4 runs of 1/0 running from front to back, 2+ and 2-. Right now, both + are running back from the + on my front battery. Would it be advantagous to run one run back from the + on the front battery, and the other from the + on the alt to the back battery bank? Advantages, disadvantages, not matter? My electrical will consist of 2+ and 2- runs of 1/0 from front to back, big 3 in 1/0, one 290 amd DC alt (2 in the future), g34 YellowTop u…

So I was just about to buy the AudioControl lc2i and I saw that it has "2 speaker-level inputs with 400 watts RMS power handling". I have 2 crescendo bc2000s and going to have 1 crescendo c1100.4. I won't be using them all at full output, but somewhere around 3.2k rms all together. Does that mean it can be hooked up to speakers that are getting up to 400 rms or does it mean that it can only support amps up to 400 rms. I looked at reviews to see if others have used with more power and they were all under 600 rms. I didn't see any other LOCs that support more power. Will the lc2i work? If it is that I can't use this one, are there any other LOCs I can? Thanks. http://www.cr…

My friend has a audiobaun htc1300 amp. He will sell me for 20 bucks. Only thing the inputs are ripped out. So I was going to get it refurbished. Good idea bad?

Does this amp work at 4 ohms?... There is no rating i could find for it at 4 ohms and id need it at that if i get it untill igot a new sub. At 2 ohms it puts out 1100 rms so at 4 would it be like 550?

I had one question and maybe a manufacturer can answer this, why is it that eq's have boost circuits instead of just reducing the overpowering frequencies? If your boost the frequency voltage, doesn't that create an undesireable risk of clipping in the system?

Help if you can, PG is ignoring my emails. I am running my PG M44 bridged to 155@4ohms x 2 to power my front stage; however, the only way I could figure out how to do this is to use RCA Y splitters and run the left RCA to both inputs on one side of the amp and the right to both inputs on the other side. Isn't there a better way to turn the M44 into a 2 channel amp? If/when I go active it will be just running my mids...

Hi everybody. I recently had my starter set up installed (2 sa-12s dvc 1 sax-1200 wired to one ohm). It was not hitting hard and then it just went completely inaudible, although bass was still slightly there. I realize the not hitting hard part was most likely a wiring issue. I took it into a car audio shop, we opened it up and the guy told me that i blew it, still very puzzling. The gain wasn't set beyond half way and I blew it, but have no idea how. Anyways, I put a picture below (downloaded from the net) and circled the place where the seal broke, and the guy who installed my stereo said it was faulty. Now the problem is bigger because I live in Taiwan, so i was …

Having a small issue with the 9884. The H/U automatically decreases the treble (noticeably) above 25 on the volume setting. Same problem when using the tuner/xm unit to which I have the gain at maximum on the xm or else it's too low. How can I turn this automatic function off? My old Cda-9827 used to crank the volume way higher with NO problem. Now I can only reach 90% of its limits before it starts changing the balance and sounds like chit. Pisssing me off

I have two sundown Sa-12s on a saz-1500d v.3 and a stock alt and battery. I'm probably in my car for an hour a day and i don't always have it turned up. Someone told me i can wire it at 1 ohm but to set the gain down. I have the big three so would this even be safe and if so what would i set the gain too?

i need 2 batterys that will replace 4 hc2000's any help plz

Has anyone used Odyssey brand batteries in their setups, and if so, how do they compare to other brands as far as disharge and keeping voltage up?

Does the SPL FX1-4000D amp do rated power? Or does anyone have experience with it?

Lately its been real hot here...over 100 several times. I park my Tahoe outside in the heat and usualy only drive it on the weekends. I have an SAZ1500D. After its been sitting for a few days ill hop in there and the bass seems to be all the way up.(As if the gain knob is all the way up). Ill unplug the cable at the knob and nothing changes, I'll go to the back and disconnect it at the amp and it lowers itself back down allowing me to control it again. Real strange to me and it has only started happening since this damn heat has hit. Any idea's? I would like to think its something wrong with the knob/wire but who knows. Edit: it is a very random thing, it doesn't do this …

im running 0 gauge, from redtop, to a kicker 1500. which the battery terminals are 2 i believe. more or less, am i gonna be using power if i use gauge reducers?

So i have 2 Earthquake PH5000/d1 amps running 4 FI SSD 15s. I have found a low popping noise in the speakers from 1 of the amps. When i unplug the RCA cables from it it gets louder. I tried switching the 2 amps and it stays on that one amp. I also have an audiocontrol in dash epicenter that can measure dbs. One night after i built the box i went for a test drive i was hitting 158 on it. the next day and since then i have not been able to hit above 155. Today i was outside messing with it and I unhooked the speaker wires from the amp that is popping and the subs on the other amp got louder. That was while the truck was running and music playing. So i hooked all 4 to the on…

Well yesterday i bought a Eclipse avn5500 for 25 bucks. Well after a quick call to eclipse to make sure it wasnt stolen i got bored and decided to hook it up in my truck. Well after I booted it up it said insert map disk.. well that's where i am stuck I am finding them on ebay for about 100 bucks any body have a spare floating around? Also what is the opinions of this H/u?

So as of now, I plan on getting 4 alpine type s component speakers, tweeters and cross overs, *I may also add two 6x9 kicker coaxial speakers* Anyways I was wondering, out of these head units, which would be the best for sq to power the speakers and which one is the most reliable. http://www.dealercostcaraudio.com/fh-p8000bt.aspx http://www.dealercostcaraudio.com/ptid-8940nt.aspx http://www.dealercostcaraudio.com/kenwooddpx503.aspx http://www.dealercostcaraudio.com/adb340mp.aspx http://www.dealercostcaraudio.com/vm9311.aspx

Again am using a US amp MD.3D. I have a HO alternator from Nations and a kenetik HC 2000. Would this be enough to supply this amp with the needed power. Am wanting to run 2 15" subs, 1000 watts a piece. Thanks in advance for the response.

Does the SAZ-3000 accept a hifonics remote gain knob cord? If not then where can I get one? any place like Fry's or radio shack have them? or adapters?

If I run 0 guage fron front batt to rear batt, then connect two amps to rear batt whats the best way....1} run single power wire to distro block fron rear batt 2} run an individual wire from each amp to the batt? Second part whats the best for grounding rear batt? run a ground back to front batt or ground to chassis or both? Also same question on grounding my amps ,to the rear batt or on the frame?
