I just saw a post from xspower and one of the questions answered was it's ability to be used as a starting battery. I want to pick up a shuriken to replace my starting battery and was just wonderin if anyone uses them as a starting batt or if they are able to be used as one. I've read they are similar to kinetiks and saw those being used as starting batts. thanks.

Just got my friend to pick up a audiopipe 1500 today, heard it is a decent budget amp. Notice it has no fuses, the guy tells me it needs external fuses. I understand what that means, but is there a distance from the amp these need to be? a certain amp rating they need to be? will the main fuse coming off the batt under the hood running to the amp be sufficient? just want to make sure i get this right before helping him install. thanks

ok so im looking for a head unit and really want a pioneer p800prs but cant find a used one. i was wondering what you guys think about the soundstream touch screens or the new clarion cz500 or the fz709 .because i can get new clarions cheap

Alright.. i ran into these things they call line drivers.. lol.. seem's pretty simple. rca's in then rca's out and bam.. higher voltage.. is it as straight forward as that? is there anything to watch out for? i see several brands including pheonix gold, rockford, hifonics and audiocontrol.. Do you guys use them? if so what are your thoughts? Just trying to get an idea of these things from all of you before i go out and buy one. cause so far its got my attention... thanks for any info you guys have.

Well, i just spent the last few days researchin this myth of Iraggi alts and kinetik batts dont go together... That sounds stupid, i know, but people have problems so i decided to try and find the answer. What i have found is interesting if you didn't know so hopefully this will help those that already have their batts and those planning on purchasing as well. A long time ago in China there was..... Oh oops, wrong story. Ok, here is the theoretical problem- Kinetik batts are only capable of accepting voltages up to 14.3v MAX Voltages above 14.3v can only be done in quick spurts. Kinetik told me that anything over 3-4hrs of constant voltage higher than 14.3v will lead to p…

I've seen on SSA before that you shouldn't mount an amp sideways because it will mess up how the heat dissipates. by sideways i mean one end of the amp facing the bottom of the vehicle, and the other facing the top. If it is true that this is a bad idea for overheating issues, why? and i need somewhat of a detailed answer; i'm arguing with an engineer and they don't accept "because the car audio professionals said so!!!" thanks and im asking because it would save a hell of a lot of space if i could mount it sideways

I'm runing two ia 21 dp's I am trying to figure out what amp to go with a incriminator audio 40.1 or a Memphis 4kw if any one can help with the pros and cons of both please and thank you

I was thinking about buying an mlx-100. I wanted to use it to take the subwoofer output on my 3sixty.2 and branch that signal into 4 outputs to power 4 of my saz1500s. (I know I could do this with y adapters as well). My question reguards sending the 4 output signals unbridged to the amps. In the video posted below they show you need to connect a and b, c and d but then stop. These are all positive polarity. Would I only be able to send identical outputs to 2 amplifiers this way? What is the deal with this? Please enlighten me. Also would it be a better idea just to get y adapters? I really don't know anything about the mlx-100 except for the fact that you could control …

Ive read several different things about this amplifier throughout this forum. Some people say its a good amp but only does its power at 2 Ohm.. i goto the actual website and it appears its stable at 1 ohm. let me cut to the chase. Friend needs a budget amp for his Fi Q 12" sub. Found a audiopipe 1500d on craigslist locally that is for sure in the budget. Guy says its hooked up so we can hear it work before purchasing. If this amp isnt 1 ohm stable then its pretty much worthless to us, since the fi Q is a dual 2 ohm sub and were planning on 1 ohm stable here. im going to attach a picture of the amp. If you guys know FOR SURE about these amp's please post, i appreciate it. …

Was looking around the pioneer site and I came across THIS man it looks sweet I cant wait to get it and replace my 880 PRS. Looks like it going to be a nice deck for SQ and wont need any external processing. The HIGHEST quality components, the best Ipod set up to date, ahhh you get it... just read about it

I have a guy that has a brand new in box Power Acoustik A1800DB amp, and he's wanting to trade it for my used Memphis 16-ST1000D. A 1800 watt for a 1000 watt.. I know PA isn't as quality of a brand as Memphis.. but it seems like a good amp. Any suggestions of whether or not I should follow through?

i just went out and purchased a multimeter so i could set the gains properly on my amp. i unhooked my subs, put on a 50hz test tone and turned my stereo up to 24/35. i put the multimeter plugs into the -/+ terminals to test voltage and all i got was 3 volts. I turned the amp up 3/4 of the way and it only gave me 9. any ideas as to what could be the problem?

we installed my single din headunit yesterday and im getting the movie playing through the speakers but not the actual video showing,could we have just missed a connection in the back?thanks for any information...

well i was driving all of a sudden the bass stopped i looked back to see all 4 subs "sucked" in so i shut down the power. (switched) remote The amp stayed on with subs still sucked in so i ripped out the speaker leads and the subs released, i then disconnected all power after i let the amp cool down reconnected power and tested with a dmm. results show 0 ac voltage and so i tried dc and got -93 volts wtf! any thoughts as to whats going on as the protection hasn't even tripped yet the fan doesn't fully engage now either. and there is definitely power coming from speaker terminals as it arced when testing(high power).

I bought a P800PRs from a online store, but they managed to send me the old version P880PRS. And since I live in Norway it's a big hassle to send it back to the US. Except from the black frontplate on the newer model and the copper plated chassis, are there any other differences between those two models?

Do I fit the power and negative cables in and take my voltage meter to the speaker out lets? I cant remember I want to test it with the stock alt wire and ground and see if I can get more power from doing the Big 3. Im sure you will suggest to use it but I want to know how much a difference it made on my truck and post up the results. Mine is a 2500hd duramax so I know I have a higher amp Alt. Plus 2 batteries already

planning on putting a head unit in a jeep wrangler 2004 just curious i did some research and its looking like i use the u pieces like on ford to pull the radio out can anyone confirm or point me in the right direction for this please.

I was all set to buy an Alpine PDX-4.100 for the front stage and a Rockford Fosgate Punch P1000-bd for my sub. Then I read some more about amps and i really like the feaetures on the JL audio stuff, specifically, that their amps put out consistent power at any impedance between 1.5 and 4 ohms and at any voltage between 11 and 14.4 volts. This seems to be worht the extra cash outlay. Also, I am well aware of the quality of JL products. My question: Is JL the only company that makes amps that will put out a consistent power across ohms and with different voltages? In my research, I was unable to find any other amps that did this. Thanks for your help. In case it …

Would anyone on the forum have suggestions regarding fair market value for the following US Amps USA 2000x? I recently purchased a new set of Definitive home audio speakers and am looking to possibly trade rid my old set to a friend for the US Amps USA 2000x pictured below. I've been out of the car audio loop for quite some time and appreciate your feedback. Thanks-Chris

I'm about to order a 25ft. roll of 1/0 gauge wire to do the Big 3. I watched the video from Maxxsonics on it too see exactly what I needed to do, and it shows him pointing out 2 separate grounds that were stock on the vehicle before he added any wire. One from the battery to the chassis, and one from the engine block to chassis. When I opened the hood on my Altima I saw that there was only one wire coming off of the negative terminal on the battery, it grounded straight to the engine block. Is this a sufficient ground, or do I still need to find another bolt somewhere on the block to make a new connection to the chassis?

I have the 9813 model head unit it has a time delay feature , easy to set by plugging in your speaker to listening position. Alpine`s web site can give you the settings for your TD . The Bass Focus is a separate feature but when adjusted it affects the time delay. I would like to use the Bass Focus but I do not understand the instructions completely. Is any one else here using this feature and how is it set?

Apparently Phoenix Gold is coming out with a High Current Amplifier Performance Auto and Sound - The Girls - The Cars - The Life - Phoenix Gold �THE ONE�

I've been reading and reading and I guess I haven't really seen it explained in a way that I understand 100% so I must ask. Let's say I have a dual 1 ohm sub, If I wire it in series to a pair of strapped amps each amp will be seeing a 1 ohm load right? When I wire it I simply sire in series to the 1st amp and just run the RCA to the slave amp?
