Q: QuestionWhat kind of amp would I need if I am running two of these in my car. .

Asked 6 years ago by Ccc0910.

• A:Answer Any decent 600 watt car amp should drive two of these easily. But if need more headroom, go with a 1000 watt car amp. There are plenty of either of those around for less than $100. Use a separate amp to drive your front speakers and/or tweeters.

Q: QuestionWhat amp can i use with one of these With of course the 250rms 1000peak 4OHM? I have the box i just need the amp but dont know how many watts i need the amp to be

Asked 5 years ago by Basshead.

• A:Answer Some ppl would tell u to go with a 250 rms Amp that's 1000 peak watts but u don't want to max out your Amp in order to drive the sub because you will have distortion after the gain gets set past around 85%. Go with one that's slightly over recommendations so to answer your question I'd personally would get a 300-350 rms Amp remember to allow time for the sub to get broke in properly otherwise u run risk of not getting the most outta your subs. Also don't pay attention to max/peak watts focus on the RMS.

Q: QuestionI have a single cab truck and need to put these in a slim truck box will they sound ok in that?

Asked 6 years ago by Anonymous.

• A:Answer I install at the Best Buy in Joliet, IL. I would rather see a client with these JBL subs rather than the Kicker series sold in the store. Best Buy sells a slim line enclosure for $80. The JBL's fit with no issues. Blows away the Kicker 10 inch truck box available in stores.

Q: QuestionFor this item, which amplifier I can use. and what are the other thing should I need to install fro my FORD FOCUS 2016.

Asked 7 years ago by Vamsi.

• A:Answer Go with the Kenwood concert series amp only sold at Best Buy. They are Kenwood Excelon amps, and they really blow the completion away in the same class of amplifiers. The JBL club amplifiers, alpine amplifiers, and pioneer amplifiers are also great amplifiers, but for the money and performance I always recommend the Kenwood amplifiers because they offer a lot more for the money, sound excellent (no noise), and are very dependable. I’ve even taken apart amps I own, compared the internals of the amplifier to my other amps, and I see much better quality components used in the Kenwood amps compared to some very reputable brands such as Pioneer. Don’t get 8 AWG as recommended in the previous answer, as that would leave absolutely no room for upgrades in the future in case you add a 4 channel amplifier in the future. I wouldn’t recommend anything smaller than 4 AWG COPPER WIRE. I personally run 1/0 AWG copper wire, as it only costs a few more $$$, and future proofs your ride for any upgrades without stressing your electrical system. I have to stress copper, because you will not get the performance you are looking for out of Copper Clad Aluminum wire. Get a ported enclosure and you will get much batter bass output when comparing to a sealed enclosure. Only time I would recommend a sealed enclosure is if you are constrained with space, or have multiple subwoofers running in a sealed enclosure as it takes much more power to get that thump you may be looking for.

Q: QuestionWhat amp can I use to run 2 of these?

Asked 6 years ago by Jake.

• A:Answer You can wire two of these to run at 2Ohm so really any amp that is 2Ohm stable bridged. Needs to be 500Watts rms @ 2Ohm minimal. I would recommend a monoblock amp. You might also want to get a capacitor.
